Embodiment 1
[0082] Embodiment 1: A multi-modal target detection method suitable for mode loss. In the following embodiment, H is height, W is width, and D is depth. The two-dimensional RGB image data collected by the camera and the laser radar are collected. Taking the two modal data of three-dimensional space point cloud data as an example, a detailed description will be given, including the following steps:
[0083] S1. Real mode generation stage:
[0084] 1) Based on the open source multi-modal data set KITTI, obtain the 3D space point cloud data and 2D RGB image data of the lidar in the same time and space;
[0085] 2), the two-dimensional RGB image data is reflected in the mathematical expression, that is, the modal feature tensor with a size of (H, W, 3), which respectively represents the height, width and RGB three channels of this image; the Resnet network is used As a feature extraction unit of two-dimensional RGB image data, the extraction accuracy is further improved, and finally
