摘　　要：针对光栅投影三维形体重建过程中,获得的相位存在2π折叠问题,采用格雷编码光栅将视场范围分割为2N个子区域,然后在每个子区域内采用相移法获得-π与π的相位,视场上每个点的相位为编码与相位的结合,依据双目立体视觉理论,就可以计算出每个视场上每个位置的深度信息。Aimed at the question arising from 2π getting fold in the phase received in the course of three-dimensional physique rebuilt through projecting the grating,this paper introduces the adoption of gray-code to code the grating for splitting the visual field range into 2~N sub-area and the use of the method of the phase shift at each sub-area,to get the phase ofπ and π.The phase of each point on the vision field is the combination of encoding with phase.The use of the three-dimensional vision theories of the eyes makes possible the calculation of the depth information of each seat on each visual field.
