The processor also generates an image feature map by extracting features of a multi-channel 2D image in which the 3D information is added to the 2D image. The processor also generates a complex feature map by mixing the image feature map and the BEV feature map. The processor also recognizes the object by artificial intelligence learning the complex feature map.
