Abstract

A method for optically detecting objects includes emitting light rays that are projected as a light line onto an object structure to be detected. The light rays are imaged on a matrix of receiving elements of a receiver to produce receiving element signals. The receiving element signals are evaluated by a triangulation principle to generate a distance profile. The evaluating includes: generating at least one evaluation window which encompasses a local range extending in a direction along the light line, generating a number of object points representing outputs of the respective receiving element that correspond to respective distances extending in a second direction, and generating a binary state information as a function of the number object points that fall within the evaluation window.
