Abstract

The applicability of the light-stripe based obstacle detection system for an outdoor vehicle was studied, and a working prototype for a laboratory environment was implemented. The prototype was implemented using a light- stripe projector and a smart photodiode matrix sensor. Special attention was paid to the ability of the algorithms to isolate the light stripes from the sensor image in an environment where a lot of unwanted light sources are present. Knowledge about the intensity distribution of the light-stripe and the performance of the known optics and geometry was used to differentiate between the light-stripe and interference on the sensor image.
