Research of depth information acquisition with two stage structured light method

3D depth information acquisition is a time consumption and costly work. This paper firstly discusses and compares three different deployments of camera system calibration. On the fundament of the calibrated camera system, this paper devises a two stage of structured light scanning method to accelerate processing speed with a high accuracy and precision. The result of the experiment shows the method will decrease the amount of processed points, and works out the problem well and can produce a satisfying depth map.
