The purpose of this project is to develop the procedures to perform the camera calibration in a three dimension range finding system. The goal is to have a system that will provide reasonably accurate range data which can be used in further three-dimensional computer vision research such as edge detection, surface recovery and object recognition. In this project, an active lighting, optical, triangulation based range finding system has been developed. The software system is designed in object oriented technology and implemented using the C++ programming language. The overall performance of the system is investigated and the system has achieved 0.5 mm (or 4%) accuracy. A review of three range data acquisition techniques is given. Based on the analysis to the current system, suggestions to future improvement are also provided.
