Abstract:  Aiming at the problem of using Kinect for rigid object 3D reconstruction under the condition of non-fixed axis and non-uniform rotation, this paper presents an improved rigid object 3D reconstruction method based on Kinect sensor. First, the depth image is acquired by the Kinect depth camera. Then the improved weighted ICP (Iterative Closest Point) algorithm is used for registration under the condition of non-fixed axis and non-uniform rotation, and all the point clouds are transformed to a universal coordinate system. Finally the 3D model surface is created based on the point cloud. The GPU (Graphic Processing Unit) programming technique is used to raise the calculating speed to meet the actual demand. The experimental results show that this method is of the advantages of good reconstruction effect.
