Ideal Auto uses Tsinghua technology to build intersection features to assist in real-time perception and mapping

The ideal "no map" solution comes from Tsinghua's technology, which mainly builds the features of intersections to assist in real-time perception and mapping. The structure of the NPN network is as follows: NPN consists of three parts: online semantic map prediction, global map prior update, and prediction prior fusion module. In summary, the ideal solution is: the road section is "no map", and the intersection is mapped by crowdsourcing.
