Abstract

In this paper, a method to eliminate the interference of the-structured light cameras is presented. 3D reconstruction is a key procedure of 3D technologies. The depth information is significant for 3D reconstruction of a certain scene and the depth camera based on structured light is widely used. This kind of cameras can get the depth information of a certain scene by emitting a beam of structured light and capture it after reflection. In order to enlarge the range of 3D reconstruction, more than one depth-cameras are used simultaneously in one scene. However, when working together, the lights emitted by those cameras would overlap in the scene. The light pattern captured by the cameras would be interfered by others and the depth they calculated would be wrong correspondingly. The method presented in this paper abstracts the progress of modulation and demodulation to a modulation matrix. Based on that, this paper provides a procedure of the whole process of interference elimination. We also optimize the matrix based on the thought of interfere alignment. Finally, the result of simulation was presented and verify the efficiency of the method.
