Device and method for in particular three-dimensional optical scanning and measuring of objects and for object recognition by means of light transit time measurement and object-dependent spatial resolution of several different individual scanners

摘要

The invention relates to a device and a method for the three-dimensional scanning of objects and for object recognition by means of light transit time measurement and preferably line by line deflection of the measuring beam by means of a micromechanical mirror. In this case, the scanner has a device for optically measuring the light transit time to an object in space by means of a transmitting and receiving lobe. One of the transmitting and / or receiving lobes is temporarily deflected by micromirrors. The measuring points are distributed according to a resolution function in the measured solid angle ranges. The resolution function depends temporally and / or spatially on the recognized object classes of one or more objects and other object parameters such as size, surface curvatures, velocity and spectral reflectivity, as well as other external parameters such as the speed of the sensor system itself in space. The scanner consists of several, typically two individual scanners.
