I don't find this fie in my data, can you tell me where I can find the tusimple_anno_cache.json, thanks.

Please follow the instructions here: https://github.com/cfzd/Ultra-Fast-Lane-Detection-v2/blob/master/INSTALL.md#41-tusimple-dataset

thanks, because I can run this data in ufldv1, so I don't deal with data for ufldv2.

@liujiachang In this part, we use a new DALI lib to accelerate the training, so new data preparation is needed.

I'm trying to migrate to my own data (intersection surveillance video). Maybe the effect is not ideal due to different angles. Do you have any good suggestions? I can make my own data set, but because the camera is fixed and can't capture multi-angle videos well, I have no idea to solve this problem. This is a example.

@liujiachang If I understand you correctly, your problem is that you only have fixed-angle images for training while you need to test on the various angle images? I think you can do some homography transformation as data augmentation, which can simulate the angle change during training.

I tried to enhance the data, and it did work, but the effect still couldn't meet the requirements. Now I'm trying to turn the picture into a bird's-eye view. Maybe only turning the camera to collect multi-angle data can really solve the problem. Thank you for your reply, which is of great help to me!
