Abstract:
1. An optoelectronic sensor for detecting an object in a three-dimensional monitored region comprising a plurality of video sensors having a multiplicity of light-receiving elements and configured to take a pixel picture of the monitored region, and a control unit adapted to identify an object from video data of the pixel picture, each video sensor including at least one pixel line formed by light-receiving elements, the video sensors being spaced from each other so that each video sensor monitors an associated plane of the monitored region, the video sensors being arranged so that the planes are one of non-overlapping and substantially parallel to each other and angularly diverging from each other in a fan-like manner beginning at the video sensors, the video sensors being further arranged so that any two planes are spaced from each other by a predetermined distance in at least a portion of the monitored region, the predetermined distance comprising 7-10 mm for the detection of fingers, 10-20 mm for the detection of extremities, and 30-80 mm for the detection of lower extremities of a human body.
