Corresponding three-dimensional panoramic model; the disclosed method, device, electronic equipment, and storage medium can accurately determine the placement position of point cloud data in the three-dimensional panoramic model, can eliminate errors caused by motor operation, and can improve the collection of point cloud data Time, improve modeling efficiency, improve the accuracy and quality of 3D panoramic model construction, and improve customer experience.

Description

technical field [0001] The present disclosure relates to the field of three-dimensional panorama technology, and in particular to a modeling method and device based on point cloud data, electronic equipment, and a storage medium. Background technique [0002] In the process of 3D modeling, 3D point cloud data is obtained by using lidar scanning, and a 3D model is formed by splicing and fusing the lidar data at different locations at different times. Most of the lidars currently used are mechanical rotating lidars (single-line or multi-line). The lidar needs to scan in a moving state, and it is necessary to accurately determine the spatial position of the data returned by the lidar in order to splice them in a three-dimensional panorama in the correct position. At present, the splicing position of the data returned by the lidar is usually determined by combining information such as IMU, historical scanning data, and algorithm estimation. The cost is high and the accuracy is ...
