Abstract

A low cost prototype of a laser range finder using a CMOS image sensor is developed for the automotive field. The system presented here is based on triangulation. The gravity of the infrared laser spot on CMOS image sensor is converted into pixel coordinates proportional to the distance to be measured. Based on the experimental tests of the system, it was found that the distance could be estimated with accuracy better than 5% within the range of 5 to 45 meters at twilight and night. Experimental results are provided and possible improvements are discussed.
