Abstract

The invention provides a modeling method and device based on point cloud data, electronic equipment and a storage medium, belonging to the technical field of three-dimensional panorama. The method comprises the steps: acquiring three-dimensional point cloud information of a scanning target collected by point cloud collection equipment and first time information thereof, rotation position information of a motor and second time information; and determining rotation position information according to the first time information and the second time information, acquiring scanning target position information based on the three-dimensional point cloud information and the rotation position information, and constructing a three-dimensional panoramic model corresponding to the scanning target. According to the method, the device, the electronic equipment and the storage medium in the invention, the placement position of the point cloud data in the three-dimensional panoramic model can be accurately determined, errors generated by motor operation can be eliminated, the collection time of the point cloud data can be prolonged, modeling efficiency can be improved, the accuracy and quality of three-dimensional panoramic model construction are improved, and customer experience is improved.

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 ...
