Abstract
In this paper, a laser vision system based on synchronous scanning technology is developed. The proposed system is composed of a fixed CCD camera, a fixed line laser projector and a scanning mirror. While the scanning mirror rotates under the control of a stepping motor, the optical paths of projection and receiver are changed synchronously. The geometrical relation is discussed for designing an experimental prototype. The experiment results obtained from the scanning system are also shown. The measurement accuracy is equivalent to the conventional vision sensors. The system utilizing the less complex mechanism can realize a wide angle-of-view 3D surface acquisition.
