Point cloud hole repairing method based on SFM

The invention discloses a point cloud hole repairing method based on SFM (Structure From Motion), which includes the following steps: (1) acquiring point cloud data through the grating projection method and the SFM method, and extracting the boundary points of a 3D point cloud hole according to point cloud 2D phase information acquired using the grating projection method; (2) registering a point cloud data set acquired using the SFM method and a point cloud data set acquired using the grating projection method; (3) acquiring the supplement points of the hole area in the point cloud acquired using the grating projection method from the data set acquired using the SFM method; and (4) based on the supplement points, using a radial basis function to further repair the hole. The algorithm is robust. The repair effect is highly precise.
