The embodiment of the present application discloses a point cloud data processing method, device, computer equipment and storage medium, including: obtaining the point cloud data to be completed corresponding to the space model to be completed, and determining the point cloud corresponding to the point cloud data to be completed Coordinate feature; obtain the autocorrelation weight matrix associated with the point cloud coordinate feature, and encode the point cloud coordinate feature based on the autocorrelation weight matrix to obtain the point autocorrelation feature corresponding to the point cloud coordinate feature; based on point Position autocorrelation features, predict the missing parts in the space model to be completed, and obtain the missing point features associated with the space model to be completed; based on the missing point cloud data corresponding to the missing point features, the point cloud to be completed The data is completed to obtain the complete space model corresponding to the space model to be completed. By adopting the embodiment of the present application, the completion efficiency of point cloud data can be improved.
Description
technical field [0001] The present application relates to the field of computer technology, and in particular to a point cloud data processing method, device, computer equipment and storage medium. Background technique [0002] At present, spatial model acquisition devices such as depth cameras (for example, 3D data acquisition equipment) are more and more widely used on user terminals (for example, mobile phones), so as to provide the point cloud corresponding to the target object (for example, 3D space model) The data collection process provides convenience. Among them, the point cloud is a collection of massive points expressing the spatial distribution of the target and the characteristics of the target surface under the same spatial reference system. "(Point Cloud). However, the inventors found that large-scale data collection will be limited by various aspects such as collection angle, environmental occlusion, and collection accuracy. The accuracy is low, the defect...
