Depth camera in computer vision and computer graphics: an overview. Journal of Frontiers of Computer Science and Technology, 2011, 5(6): 481-492. Abstract: An increasing number of applications depend on accurate and fast 3D scene analysis, such as geometry reconstruction, collision prevention, mixed reality, and gesture recognition. The acquisition of a range map by image- based analysis or laser scan techniques is still time-consuming and expensive. Emerged as an alternative device to measure distance, depth camera enjoys some advances, e.g., lower price and higher photo speed, that have not be *The National Natural Science Foundation of China under Grant No.(); the Nation
