| titleOfInvention | A 3D map creation method based on 3D laser |
| abstract | The invention discloses a method for creating a 3D map based on a 3D laser, which belongs to the technical field of data processing. The feature extraction of the data frame is performed to obtain the feature points of the point cloud data frame; the transformation matrix is optimized according to the LM algorithm, and the transformation matrix that minimizes the squared sum of the distance errors of all feature points is used as the pose of the radar; according to the pose of the radar , which converts each frame of point cloud data into a point cloud map in the global coordinate system, and converts the point cloud map into a voxel-expressed map. By processing the original laser data with rich information, it provides a data basis for the next step of creating a 3D map. By adopting the expression form of voxel map, the problem of inconvenient filtering and denoising of the point cloud map is avoided, and the clarity of the 3D map is improved. |
