MambaBEV: An efficient 3D detection model with Mamba2

A stable 3D object detection model based on BEV paradigm with temporal information is very important for autonomous driving systems. However, current temporal fusion model use convolutional layer or deformable self-attention is not conducive to the exchange of global information of BEV space and has more computational cost. Recently, a newly proposed based model specialized in processing sequence called mamba has shown great potential in multiple downstream task. In this work, we proposed a mamba2-based BEV 3D object detection model named MambaBEV. We also adapt an end to end self driving paradigm to test the performance of the model. Our work performs pretty good results on nucences datasets:Our base version achieves 51.7% NDS. Our code will be available soon.
