Abstract

A prototype of range finder using a CMOS image sensor and a pulsed laser is developed for the automotive field. The system presented here is based on optical 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 2% within the range of 5 to 45 meters.
