MMDetection3D V1.0.0rc0 Release

Compatibility

• We refactor our three coordinate systems to make their rotation directions and origins more consistent, and further remove unnecessary hacks in different datasets and models. Therefore, please re-generate data information or convert the old version to the new one with our provided scripts. We will also provide updated checkpoints in the next version. Please refer to the compatibility documentation for more details.
• Unify the camera keys for consistent transformation between coordinate systems on different datasets. The modification changes the key names to lidar2img, depth2img, cam2img, etc., for easier understanding. Customized codes using legacy keys may be influenced.
• The next release will begin to move files of CUDA ops to MMCV. It will influence the way to import related functions. We will not break the compatibility but will raise a warning first and please prepare to migrate it.
