摘要： An optoelectronic sensor (10) for monitoring a working area (42) is provided, the working area (42) being located within a detection area (20) of the sensor (10) and in a first distance from the sensor (10), wherein the sensor (10) comprises an illumination unit (22) with a light source (24) for at least partially illuminating the working area (42), and an object detection unit (30) for detecting forbidden objects in the working area (42), wherein an illumination control (28) of the illumination unit (22) is configured to, during a startup period, initially activate the illumination unit (28) with a lower power such that a provisional working area (40, 40a-c) in a second distance from the sensor (10) less than the first distance is illuminated at most with a predetermined maximum light output; test whether there is a forbidden object intrusion into the provisional working area (40, 40a-c); and if no forbidden object intrusion is detected, activate the illumination unit (28) with a higher power such that the working area (42) is illuminated at most with the predetermined maximum light output. The illumination control (28) comprises a short range object detection unit (39) configured to test the provisional working area (40, 40a-c) in a different way than the object detection unit (30) tests the working area (42).

摘要： A distance-measuring optoelectronic sensor for the monitoring of a working zone is provided which is located within a detection zone of the sensor and at a first distance from the sensor, wherein the sensor has a lighting unit having a light source to illuminate the working zone at least partly as well as an object detection unit by means of which unauthorized objects in the working zone can be detected. In this respect, an illumination control is designed, in a switching-on phase, first to activate the lighting unit with a lower power so that a provisional working zone at a second distance from the sensor less than the first distance is illuminated with at most a preset maximum power; to check by means of the object detection unit whether an unauthorized object intrusion is taking place into the provisional working zone; and if no unauthorized object intrusion is recognized, to activate the lighting unit at a higher power so that the working zone is illuminated with at most the preset maximum power.

摘要： A 3D sensor (10) having at least one image sensor (14) for the generation of image data of a monitored region (12) as well as a 3D evaluation unit (28) are provided, the evaluation unit (28) is adapted for the calculation of a depth map having distance pixels from the image data and for the determination of reliability values for the distance pixels. In this respect a gap evaluation unit (28) is provided which is adapted to recognize regions of the depth map with distance pixels whose reliability value does not satisfy a reliability criteria as gaps (42) in the depth map and to evaluate whether the depth map has gaps (42) larger than an uncritical maximum size.
