Abstract

For quality control, volume determination, process monitoring and other tasks in industry, the application of 3-D measurement techniques is required. Out of the available 3-D methods, the optical radar shows special advantages. In this context, a system based on the method of optical radar as well as first results is described in more detail. The new system provides data for 3-D scene analysis with the spatial coordinates of a surface to be determined in a pre- defined volume. A complete 3-D picture with 500 X 500 pixels is recorded and evaluated within less than 2 seconds.
