Meaning of "ida, bda" in the dataset script #44

Open NJUEELJN opened 2 years ago

NJUEELJN commented 2 years ago

Hi, thanks for opening access the nice work! I have a question about the meaning of "ida" that shows up a lot in the dataset script e.g. ida_transformation , and does it mean transformation among different view cameras?

yinchimaoliang commented 2 years ago

Hi! ida denotes image data augmentation and bda denotes bev data augmentation.

Hi! ida denotes image data augmentation and bda denotes bev data augmentation. Thanks really! And to be specifically, does ida_matrics refers to camera extrinsic parameter of the camera to vehicle?

Hi, I'd like to konw if I use my own data. How to caluate the BDA and IDA? If there is no augmentation of bev label, what's the IDA data?
