| description | The present invention relates to the technical field of point cloud data, and in particular, to a registration method and system. The method comprises: performing lens distortion correction on a digital camera, obtaining internal and external parameters of the digital camera, and performing distortion correction on extracted image data; denoising and simplifying a three-dimensional laser point cloud; using POS information data to obtain timestamps of image data captured by the digital camera and a point cloud scanned by a three-dimensional LIDAR at the same time, extracting initial registration values corresponding to the image data and the laser point cloud from POS data, and performing initial registration on the basis of a collinear equation model; and on the basis of an iterative closest point algorithm, using a high-precision registration value as an initial value of the iterative closest point algorithm, and using an image data point cloud and the laser point cloud to perform iterative closest point reg |
