Subject:

Development and Implementation of New Image Processing Methods for Robust Laser Profiler Operation

Introduction:

The digitization and reconstruction of 3D shapes has numerous applications in areas that include manufacturing, virtual simulation, science, medicine, and consumer marketing. In DLR we have developed a Laser Scanner that acquires accurate range data through optical triangulation.

Tasks:

Besides proper calibration and operation of a laser profiler (already done in this project), there still remain some inherent errors in the profiler operation. The standard methods for extracting range data from optical triangulation scanners are accurate only for planar objects of uniform reflectance. Using these methods, curved surfaces, discontinuous surfaces, and surfaces of varying reflectance cause systematic distortions of the range data. This work is intended to study already developed algorithms for coping with these problems (e.g. spacetime analysis) and implement either already developed or new algorithms in the DLR Laser Profiler Device.
