Abstract:
1. A method for the detection of an object moving in the monitored region of a camera, wherein an actual image of the monitored region is recorded by the camera; at least one actual measured value is derived from the actually recorded image which provides information on differences between at least two different image regions and which is invariant with respect to image displacements, image rotations and/or image size changes; this actual measured value is compared with a corresponding reference value derived from a stored reference image recorded by the camera; an object recognition reaction is triggered on a pre-set deviation of the actual measured value from the reference value; a structure, which is a component of the image, is superimposed on the reference image and the actually recorded image, the reference value and a measured value being gained from the corresponding structure information; and a check is made whether the camera is in working order by recording images regularly with and without a structure generated in the monitored region and by checking whether the structure information is found with a generated structure and is not found with no structure generated.
