[zytx121]

This issue describes the development requirement of a feature we wish to collaborate with the community.
In this issue, we welcome the community developers to participate in the development of Oriented RepPoints.

Description

Support OrientedRepPoints. You can use points_in_polygons op in mmcv to judge whether points are inside polygons.

Steps

• Add OrientedRepPointsHead and SpatialBorderLoss in MMRotate
• Benchmark the performance
• Prepare and release the models

Hello, I'm preparing the codes of Oriented RepPoints for MMRotate.
The chamfer distance 2d used in Oriented RepPoints needs cuda compile. I bulid a new ops folder like old version, then compile it in the environment of MMRotate successfully. But the error of error in nnd updateOutput: invalid device function appears during the training.
Can you help me to make chamfer distance 2d op avaliable in the mmcv like points_in_polygons.

The resources of chamfer distance 2d are here:

When I validate the model on DOTA，I can't figure out the range of mAP . Is it from 0-1 or 0-100? Thanks for your replay!
