Embodiment 1
[0027] image 3 is a flow chart of a time synchronization-based obstacle heading angle calculation method according to an embodiment of the present invention, such as image 3 As shown, the method includes the following steps:
[0028] Step S302, obtaining a heading angle calculation model, wherein the heading angle calculation model is obtained through training on the heading angle yaw value historical data.
[0029] Optionally, the heading angle calculation model adopts a double-chain layer DNN network model.
[0030] Specifically, in order to solve the perceptual detection algorithm of the prior art, it is difficult to calculate the yaw angle of obstacles using image perception, and the results are also difficult to be accurate; it is not easy to calculate the yaw angle of obstacles using traditional point cloud clustering algorithms Accuracy and stability cannot be guaranteed. Secondly, the calculation of the obstacle heading angle also involves the own vehicle heading ...
