The depth perception of objects in a scene is the primary research objective of the machine vision system. Ithas many industrial applications, such as robot navigation, scene understanding, metrology, etc. In this paper, someissues of low cost image processing based distance estimation systems are described. The low cost systems use commonlyavailable laser pointer pens and a web camera. These systems are based on the principle of triangulation along with theperspective projection and the fact that light travels in a straight line. The paper presents a prototype system of a laserrange estimation system consisting of a laser light pen and a webcam. The main contribution of the paper is a simpleprocedure for the system calibration and the camera parameter estimation. The system is implemented in the Matlabenvironment and gives good results.
