Claim 16:
17. The object detection apparatus according to claim 16, wherein the instructions further configure the one or more processor to:
perform the 3D convolution operation on the feature information of the 3D voxel by using a 3D convolutional network in a region proposal network (RPN), the RPN further comprising a 2D convolutional network connected to the 3D convolutional network, the 2D convolutional network comprising a plurality of convolutional blocks sequentially connected;
perform a 2D convolution operation on the 3D convolution feature information sequentially by using the plurality of convolutional blocks in the 2D convolutional network; and
fuse convolution features outputted by the convolutional blocks to obtain the convolution feature set.
