Abstract:
A method for optically monitoring an object within a monitoring area includes transmitting light rays with a light transmitting unit that form a line of light on the object. The line of light reflected from the object is imaged on an array of receiving elements that detects the reflected line of light and produces receiving element signals that correspond to measuring points on the object. The receiving element signals are evaluated to structure a distance profile of the object using a triangulation principle. The evaluating includes generating at least one evaluation window which covers in a first direction a local region extending along the line of light and in a second direction a distance range, and using the measuring points located farthest outside within the evaluation window for a left limit point and a right limit point for determining object data.
