3d safety sensor and method for testing a 3d security sensor

摘要

The sensor (10) has an image evaluation unit (2) including two inputs that are selectively connected with an output of cameras (11, 12) or an output of a storage for a test pattern (7) via switches (21, 22). An output of the evaluation unit is selectively connected with an input of a comparator (3) or an input of an error detector (8) via a switch (23). An output of the comparator is selectively connected with an input of a protection area intrusion-output unit (5) or the input of the detector via a switch (25). An independent claim is also included for a method for testing a three-dimensional safety sensor.
