2D target detection benchmark #616

Closed Majiawei closed 3 years ago

Majiawei commented 3 years ago

Is there a method for 2D object detection on nuscense dataset? Or is there a comparison of 2D object detection on nuimage? I found that the 2D annotation converted from 3D annotation in nuscenes dataset can't fit the object well. Can I use the converted data for 2D detector training?

nuScenes did not come with 2d annotations. nuImages did. As you saw, there is a script to project 3d boxes to 2d, but they are generally not tight in 2d. You can definitely use it, but it will be slightly worse. Better would be to use these models trained on nuImages: https://github.com/open-mmlab/mmdetection3d/tree/master/configs/nuimages
