Description

State of the art

The present invention relates to a method for transmitting data between at least one mobile data acquisition device and a server device connected to a telecommunications network based on visually detectable and at least one object class having image information.

Furthermore, the present invention relates to a system for transmitting data between at least one mobile data acquisition device and a server device connected to a telecommunications network based on visually detectable and at least one object class having image information.

Furthermore, the subject of the present invention is a data acquisition device for the transmission of data between the data acquisition device and a server device connected to a telecommunication network based on visually detectable and at least one object class having image information.

Furthermore, the present invention relates to a computer program and a computer program product.

In today's information systems installed in vehicles, it is possible that traffic signs are automatically detected. Furthermore, it is known to use this information for the functionality of navigation systems. For this purpose, in particular camera devices, for example, mounted on the windshield, are provided, which are in particular permanently installed in the vehicle. In such systems, the functionality of pattern recognition is typically implemented so that the meaning content of traffic signs that are visually detectable by the camera device can be used by the information system or the navigation system. In such systems, however, there is normally no connection to a server device by which a communication link in the uplink direction (i.e., "uplink" from the terminal within the vehicle towards the telecommunications network). This means that the information visually detected by the camera device is only available within the vehicle, and in particular not in a centralized server device.

Furthermore, from the document WO 2010/046193 A1 a device or a method is known in which by means of a vehicle-mounted sensor system in particular information relating to detour signage are collected and transmitted to a traffic information center. However, this system is intended only for processing certain characters, namely traffic signs, so that extending functionality to recognition of other characters requires updating the vehicle-mounted system components.

There are also known visually detectable, in particular two-dimensional codes, for example the so-called QR code (quick response code), which are used in connection with various applications. Such codes, especially two-dimensional codes, are relatively easy to generate, display and print. Normally, the use of such two-dimensional codes or the use of QR codes presupposes an active user action, for example the triggering of a camera application.

Previously known systems which use image recognition to collect relevant information for their respective applications - for example traffic sign recognition - are usually based on the processing of visual information, which is also recognizable to humans, such as traffic signs, pictograms or written texts. Other specific applications, such as those incorporated into devices such as cameras, are so equipped or have the functionality that objects - such as a person's faces or closed eyes - can be automatically identified and influence the behavior or functionality of the device accordingly (For example - for the example of a camera - the focus control (focus or autofocus) or the control of the shutter release). Previously known applications that are capable of identifying and processing information that is not human-readable (for example, bar codes or QR codes) typically require interaction with a human, such as in the form that a stripe code reader is used or that the camera of a mobile phone is directed to a QR code that has attracted the attention of a user of the mobile phone.

This two-stage identification process (or pattern recognition process) can greatly reduce the processing required for pattern recognition. During the continuous scanning (or the continuous search) of the field of view of the camera device (in the first step) only relatively large (ie having a large solid angle or to be detected with a low resolution) and strictly defined patterns must be detected (for example, rectangular green Borders with the icon of the letter "i" in the upper left corner of the border are defined as an information posting (or posting of information) comprising a QR code). The specific information content (ie the content data of the second kind) of the concrete (lower resolution) recognized object (content data of the first kind) from the object class need only be analyzed or recognized when the data acquisition device is operating in such an operating mode that objects of that object class actually need to be evaluated. Other objects or objects of other object classes (for example, bar codes in a blue circular border, which are defined for traffic control purposes, for example) can then be ignored in such a situation or operating mode of the data acquisition device when performing the second step, i. Such objects of another object class are indeed recognized in the first processing step (with a lower resolution), but recognized as not being considered further and thus ignored in the second step.

According to the invention, it is particularly advantageously possible for digitally readable information, for example signs or posters (posters) or digital posters (postings) (postings or digital postings), to be displayed or suspended in a manner and in places that are digital readable information from passing user or their data acquisition devices 20 can be read or recorded. According to the invention, it is provided that the image information that can be detected by the data acquisition device comprises at least one object class 300 exhibit. From the picture information 200 become content data by processing the image information 220 generated on the at least one object class 300 are related. According to the invention, at least a part of the at least one object class 300 related content data 220 from the at least one data acquisition device 20 to the server device 130 transfer. Furthermore, it is provided that the at least one object class 300 related control data 240 either from the server device 130 or by the user to the at least one data acquisition device 20 be transmitted.

According to the invention, the data acquisition device 20 a pattern recognition system and is connected to the server device 130 via a telecommunications network 100 or in particular a mobile network 100 connected. By means of the data acquisition device 20 (or in particular by means of a plurality of data acquisition devices 20 provided in the manner of a fleet), it is possible according to the invention that image acquisition operations can be performed which are flexibly usable in a large number of applications.

The digitally readable information, for example signs or postings (postings or digital postings), are according to the invention in particular in the form of at least one object class 300 such information. An object class 300 is inventively preferred in a simple manner recognizable. The information of an object class 300 may have a specific shape and / or a specific color and / or a specific border and / or additional markings and therefore represent meta-symbols. The additional markings may be, for example, indications in the form of individual characters such as an exclamation mark, a question mark, a letter "i" (standing for "information"), a letter "P" (standing for parking) or the like. In particular, by the specific shape and / or the specific color and / or the specific border - but possibly also by the additional marking - are the respective visually detectable information in each object class 300 relatively easily detected in pattern recognition process, ie recognizable. According to the present invention, such a posting becomes part of a data acquisition device 20 Visible visually detectable information recognized as soon as they are in the field of view of the camera device 21 the data acquisition device 20 appears. Subsequently, a pattern recognition process is performed and as one to the object class 300 associated information detected (content data of the first kind 221 ). Provided the recognized object class 300 as a (for the user or the data acquisition device 20 ) relevant object class 300 is understood, the digital content (content data of the second kind 222 ) of the respective information (or postings) read and fed to a further processing.

Thus, according to the present invention, there is provided a method of generating graphical representations as meta-symbols for various classes of postings relating to different standardized use cases, such meta-symbols being readily accessible by pattern recognition systems due to their shape, their outline, their color or any other graphical characteristic are identifiable and wherein the meta-symbols are created or designed in such a way that in the same area of the metasymbol (or in the same area or at the same place of the display area) a variable Information - typically a variable binary or digital information - as information content (or content data of the second kind 222 ), wherein the information content is provided, recognized and transmitted, wherein the information content is provided or shown in particular in the form of a QR code.

According to the invention, the method for transmitting data is preferably carried out in two stages: After the detection or detection and identification of relevant information or of a "postings" of interest (content data of the first kind) 221 ) is done in a second and subsequent step the - in particular machine readable, in particular present in binary form - information (content data of the second kind 222 ) read and processed.

In the event that the information (content data of the second kind 222 ) represents a uniform identifier for resources (URI, uniform resource identifier, or URL, uniform resource locator) - that is, for example, a link to an Internet address - as information content, is the data collection device 20 configured such that the link is automatically activated by accessing the resource via a mobile communication link using the telecommunications network 100 is accessed. Below is a via this link to the respective Internet address retrievable information to the data acquisition device 20 transmitted and made available to the requesting application. Additional method steps may be provided for those cases in which an interactive communication with an application on a remote network node (eg, in the server device 130 ), which is represented by the common identifier for resources or by linking to an Internet address, is required. In this context, it is provided according to the invention in particular that authentication methods are used, that an exchange of information regarding the respective functionalities of the devices involved in the communication takes place (exchange of device capabilities), that information relating to billing operations is transmitted or exchanged, and / or that a transmission and / or exchange of geoposition data and / or geolocation data, in particular the data acquisition device 20 , he follows.

In the event that the information read (content data of the second kind 222 ) is textual information only and does not represent a common identifier for resources or any link to an Internet address as information content - for example, in the form of a code encoded as a QR code or in numbers or numbers as a bar code - will not access a remote system or a remote network node or the server device 130 carried out; the text information is provided merely as plain text information to the requesting application.

According to the present invention, it is preferably provided that the inventive method is carried out in an optimized form such that a scan (or a search) of the entire field of view of the camera device 21 is performed in a first step with a comparatively low resolution of the image processing system, the resolution of the image processing system being chosen such that the resolution is just large enough to produce the meta-symbols (ie the content data of the first kind) 221 ) recognize or identify. Only after such an identification or recognition of the metasymbols is the full resolution of the camera device in a second step 21 used in the data processing or the evaluation of the image information to the digital content (content data of the second kind 222 ) which is present within or embedded in the area of the metasymbols or "postings". Due to continuously changing distances between on the one hand a moving data acquisition device 20 (or the camera device 21 such a data acquisition device 20 ) and on the other hand the representation of the metasymbol or "posting", the second step may need to be repeated several times until an error-free identification is done. As already stated, in order to reduce the data processing effort for image processing or image recognition, it is preferably provided that this processing of specific metasymbols or postings provided in the second step is limited to those metasymbols that are relevant in a usage situation, in particular relevant for a user the data acquisition device 20 or due to a default of the data acquisition device 20 , in particular one by the server device 130 default setting of the data acquisition device 20 , According to the invention, it is further preferred that a meaningful use and / or implementation of the image recognition according to the invention taking into account the situation or the context takes place, in particular with regard to processing cycles or repetition rates of the image processing; for example, the corresponding repetition rates or processing cycles will differ considerably, depending on whether the situation is that of a comparatively fast-moving vehicle for which meta-symbols or postings are relevant for route guidance, or whether it is the situation of a wheelchair user Navigating a mall to find the fastest access to an accessible coffee shop. In both cases, the data collection device 20 Metasymbols that are in the image field of the camera setup 21 locate, filter and filter, using a situation-adjusted refresh rate or image processing rate, for relevant object classes (such as metasymbols that serve traffic guidance vs. metasymbols that support mobility impaired people). The rate of appearance and the duration of visibility of certain metasymbols or postings can advantageously be used according to the invention to determine a meaningful sampling rate or repetition rate whose frequency is at least twice as high should be like the shortest time period previously observed for the visibility of a meta-symbol for the camera setup 21 was.

Specific examples of the information content (content data of the second kind 222 ) of a meta-symbol or post could be: "Take the next exit for John F Kennedy Airport" or link to a website to access additional information: " www.hotelfinder-berlin.info ". According to the invention, it is further preferably provided that the processing of received data or information from metasymbols or postings can also be combined with the results of other methods of pattern recognition of existing systems, such as those which automatically recognize traffic signs or other human-readable textual information or even pictograms or identify. All of these process steps require a similar configuration of the hardware and can be integrated into a single system.

An example scenario for the use case or the user mode "User Guidance" is shown below:
Based on current user preferences and logical filters (such as "Find the nearest pizzeria and associated parking space"), the system will look for relevant postings or metasymbols in the field of view of the camera setup 21 search, read or read their contents (such as the GPS coordinates of restaurants, recommendations for urban traffic guidance) and, in the case of found relevant information, output specific user information or navigation information to the user, for example via a display device or via an acoustically transmitted Message (audio message), whereby the output message could, for example, be as follows, depending on the information detected by the recorded post or recorded postings: "Take the second left to park near the restaurant 'Paste e Pizze'; then walk 50 m in the direction of the metro station and find the restaurant on the right side of the street ".

According to the invention, it is preferably provided that the logic of the respective user guidance does not only include information of the metasymbols, but also information from other sources, such as navigation systems, traffic information systems and a geopositioning system. In any case, however, the user guidance can be supplemented or supplemented by the information available on the basis of the postings in relation to such other sources. In particular, according to the present invention, it is advantageously possible for the functionality of conventional navigation systems (so-called turn-by-turn navigation systems) or comparable devices to be provided by the user guidance information that is made available locally by means of the postings (as physical-sign posts). is extended, whereby it is advantageously possible in particular according to the invention that the user interface is without access to a central database and the use of interfaces for changing data is not required.

These postings may be prepared or provided by public authorities and / or by companies and / or individuals. They can also be permanently integrated in masts - for street lighting, for example - or in advertising signs. Furthermore, the postings can also have a flexible content, such as an electronic display for specific applications or also - but not limited to - for traffic management and / or for public safety. Other examples include advertising, in particular combined with customer guidance about special offers or shops.

Another example includes postings for improved traffic guidance or control, particularly in higher-end vehicle classes already equipped with on-board camera facilities and image processing functionalities, such as the automotive industry or public safety initiatives. Other exemplary implementations include digital postings (eg, citywide within a city) to assist persons with reduced mobility. In the event that QR codes (as content data of the second kind 222 ) are used within these postings, it is preferably possible in accordance with the invention that the information content of these postings is also accessible to the general public, for example by merely creating an image using a mobile phone equipped with a camera device and accessing the associated Internet link. This makes it advantageously possible according to the invention to provide comparatively low-threshold access to the use of the postings according to the invention - without the necessity of having a system for automatic scanning and pattern recognition available with a camera device.

While visual signs that are omnipresent in today's public space always require the conscious attention of a user or person, it is advantageously possible according to the invention for the environment to be automatically identified in specific and user-defined postings by means of the image recognition system Users are of interest, is searched.

An exemplary scenario for another use case or mode of use, namely "automatic information capture", is shown below:
A mobile image recognition system (data acquisition device 20 ), for example on board a motor vehicle, according to a preferred embodiment of the present invention is used to be remotely controlled by a central information acquisition system (or server device) 130 ) providing authorized access to the mobile image recognition system (s) 20 Has. Specific commands or commands of the central system or the server device 130 are provided for collecting information tasks on the mobile system or the data acquisition device 20 to activate based on their image acquisition functionalities and their image processing functionalities. According to the invention, it is provided in this case that a plurality of data acquisition devices 20 or a whole group of data acquisition devices 20 or a fleet is used for one (or more) information gathering task. In this case, the mobile system or the data acquisition device works 20 in the manner of an agent system for the central information collection system or the server device 130 in that certain information-gathering tasks are processed, as will be described in more detail below, for example, wherein in the case of a permanently installed on-board system, in particular in a vehicle, the data acquisition device 20 For example, is designed such that parts of the built-in system by the data acquisition device 20 can be shared, so in a time-sharing mode, these parts of the built-in system for data collection device tasks 20 but also for fixed-system tasks.

According to one application example, for example, advertising spaces for a specific advertising campaign are provided with the postings according to the invention, the postings having, for example, QR codes. The information gathering task sent to a mobile agent system or to a plurality of mobile agent systems (or to one or more data collection devices 20 For example, transferring the data generated by, for example, the vehicles of a taxi fleet or the devices incorporated or carried therein), is to register all the situations or events in which the particular posting (as part of the advertising campaign's ad space) is recognized was (ie the posting came in the field of view of the camera setup 21 the data acquisition device 20 and was recognized due to the image processing performed). In the event that, for example, the information content of the posting (ie the content data of the second kind 222 ) is such that the QR code representing the character string " www.t-mobile.at/XmasSale "- possibly with an indication that it is an Internet connection - has, it is advantageously possible according to the invention that the previously - in particular in connection with the user mode" user interface "- described methods and principles are applied to meta-symbols recognize and read the digital content of postings or capture and perform the corresponding further processing steps or measures.

Subsequent to such identification of such posting (ie posting with, for example, a QR code containing the string " www.t-mobile.at/XmasSale Information regarding the successful identification, for example in the uplink direction (ie a connection with the data flow direction, which is from the point of view of a terminal in the direction of the telecommunications network) to the requesting information system (ie usually to the server device 130 ), in particular the current GPS coordinates (or generally coordinates of a satellite-based positioning system) and possibly other related information - such as the instantaneous speed of movement of the data acquisition device 20 (ie the vehicle with which the data acquisition device 20 is carried) or the residence time of the posting in the detection range of the camera device 21 the data acquisition device 20 - also be transmitted. The transmission of this information or information (ie the information regarding the successful identification and possibly other related information) from the agent system (or the data acquisition device 20 ) to the central information system (or the server device 130 ) can be done either individually for each situation of recognizing or identifying a posting (ie, in particular in real time (comparatively short term) after the detection has been performed) or as a transmission (over a certain period of time) of such information collected. This results in the requesting central system (ie the server device 130 ) provide a good statistical basis for the visibility of the display campaign's display area within a particular region (which, of course, is due to the typical driving patterns of the vehicles in the fleet or, more generally, the plurality of data collection devices 20 is defined).

Thus, according to the invention, it is advantageously possible that schemes for collecting information can be implemented in an efficient manner beyond that are usable in a flexible manner. In this case, according to the invention, it is advantageously possible for all combinations of, on the one hand, different possibilities for the realization of data acquisition devices 20 (Participating front-end users or user groups as agent systems) with on the other hand different server devices 130 (or backend systems or information systems) can be realized, since the devices or data acquisition devices according to the invention 20 several tasks simultaneously or in a multitasking approach are able to, at least up to a certain processing capacity or depending on the prioritization of the various tasks or communication capacities or available bandwidths of the devices or systems involved.
