Help for nuscene's tracking!!!

[qfwysw]

I use the transformer to predict the offset between the pre and cur frame. When I visualize the result of the offset, it works great. However, when I run the pub_test, it gets the low grade. I modified the code below. det['tracking'] = np.array(det['tracking1'][:2]) * -1 det['tracking1'] = cur_box - pre_box . It really makes me confusion. can you give some advice？

I am not very sure, but maybe there are some coordinate transform missing?

Make sure that you also transform this offset to the global coordinate to use this pub test file.

Let me know if you have further questions. I am happy to help
