Definitions
- a number of objects are provided with said marking means, where the objects 20 are monitored for uncontrolled displacement.
- False markers can eventually appear if there are many bright objects in an image, which 10 the camera apprehends as a reflex mark. False markers can be filtrated in most of the cases by means of that the measuring system contains information concerning the shape of each mark. The false markers, which eventually remain after the filtration, are no problem since they are in fact stationary. Varying strong sunlight may cause problem through dazzling the system, but by means of appropriate camera location, such problems can be eliminated. 15
