A 3D Coordinate Measuring Machine (CMM) using stereo vision with line laser was developed in this research. The laser line on the target surface was taken by two CCD cameras. Stereo vision, a technique calculate 3D coordinate from corresponding pixel in each cameras, used for 3D reconstruction to enhanced the precision of machine and make the machine more flexible in real application. The point cloud from the machine can be exported to CAD application software such as CATIA. Tested with continuous and complex surfaces, the machine has shown its performance to achieve good result. The accuracy of this machine is about 350 micron (0.35 millimeters) when calibrated at 100 millimeters from the top of Z axis. The accuracy can be improved with better quality of the line laser. Working-space of the machine is inside the 200x150x120 millimeters (width x length x height).
