| titleOfInvention | Joint positioning method for spatial points by means of onboard LiDAR point cloud and high resolution images |
| abstract | A joint positioning method for spatial points by means of onboard LiDAR point cloud and high resolution images includes the steps: denoising original LiDAR data; generating a high-precision DEM (digital elevation model); manually supplementing elements of exterior orientation of images acquired by high-precision POS (point-of-sale) data; calculating object-side coordinates (X, Y and Z) of identical points by means of multi-image forward intersection after calculating initial values by means of two-image forward intersection by the aid of two optional points among the selected identical points; and obtaining precise object-side coordinates (X, Y and Z') corresponding to the identical points by the aid of the object-side coordinates of the identical points solved by means of previous multi-image forward intersection. By means of multi-image forward intersection realized on the premise of elevation constraint of the LiDAR point cloud, object-side coordinates of acquired image points are quite high in plane precision and elevation precision. |
