混合3D模型跟蹤注冊(cè)算法
[Abstract]:In the maintenance guidance system, the registration algorithm based on 3D model requires manual initialization of position and pose, easy to generate error offset, and can not automatically update 3D model, and many other problems, such as manual initialization of pose, error offset and automatic updating of 3D model are needed in maintenance guidance system. A hybrid registration algorithm for 3D model tracking based on edge features is proposed. Firstly, the number of edge pixels is selected as the measure standard, and the particle filter algorithm is used to initialize the camera position and pose. Then the nonlinear least square error estimation algorithm is used to continuously update the pose estimation, and the error offset is eliminated by real-time monitoring of the number of control points in the model. Finally, key point matching is used to realize process recognition and real-time updating of 3D model. The experimental results on the prototype system show that the algorithm has strong stability and high efficiency, and can effectively overcome the error migration.
