About the issue of image flipping in image data augmentation #319

Closed fengdian8564 closed 11 months ago

It is a question about image flipping in image data augmentation. The question is about the founction named sample_augmentation in 'mmdet3d/datasets/pipelines/loading.py' I found that adding 180 to rot rather than flipping the image vertically when the vflip is set to True. Is there any considerations to do that？

Looking forward to your reply

@fengdian8564 hflip+rot180=vflip

Why not just do hslip and vslip directly？
