Abstract

The invention provides a point cloud data identification method and device, electronic equipment and a storage medium, and the method comprises the steps: obtaining single-frame point cloud data, and segmenting the single-frame point cloud data into a preset number of local data; inputting the local data into a preset number of PointNet + + networks in parallel, so that the PointNet + + networks extract local features corresponding to the local data; inputting all the local data into a ViT network to enable the ViT network to extract global features of the single-frame point cloud data; fusing the local features and the global features to obtain fused features, and performing type identification on the single-frame point cloud data by using the fused features; according to the method, the Point Net + + network and the ViT network are combined to identify the point cloud data, the global features of the point cloud data can be effectively extracted, and the global features and local features of the point cloud data can be well integrated, so that the perception and identification effects of the point cloud data can be effectively improved.

Description

technical field [0001] The invention relates to the field of pattern recognition, in particular to a point cloud data recognition method, device, electronic equipment and computer-readable storage medium. Background technique [0002] Compared with the two-dimensional image data provided by traditional cameras, the point cloud data provided by lidar can contain three-dimensional depth information, and can eliminate the interference of light conditions, which can effectively improve the perception performance of unmanned driving systems. In the field of driving, object recognition tasks are often performed using point cloud data. In related technologies, point cloud data recognition algorithms have shortcomings in the extraction of global features, and cannot effectively integrate global features and local features in point cloud data, making it difficult to obtain better perception effects. Contents of the invention [0003] The object of the present invention is to provi...
