Point-clouds registration algorithm based on improve projection

According to the traditional ICP algorithm in convergence speed or the registration accuracy failed to meet the demands of the real-time measurement,this paper described an accurate and efficient algorithm of point cloud registration that suitable for single and binocular structured light three-dimension measurement system.First the reference point cloud sampling point back projected to the destination point cloud of the 2D image plane,and then forward-projected the source point to the destination surface.The paper showed that iterative projections of the projected destination to the normal vector converge to the intersection point.Actual measurement result shows that the method to ensure the accuracy of registration while the convergence rate is significantly pricey,and it is a high practical of registration algorithm.
