[MMDetecion3D] Meaning of Evaluate

https://github.com/open-mmlab/OpenPCDet/issues/432

 

 

• The metrics go like this. AP@ Easy , Medium , Hard (3 columns) .
• AP@0.70 means Average Precision with Intersection over Union (IoU) with threshold at 70% .
  [which basically means that predictions with IoU less than 70% won't be considered as correct].
• AP_R40 means Average precision with 40 points approximation on the Precision-Recall curve.
  (when you see plain 'AP' it's with 11 points).

• IoU is calculated either in camera (2D bounding boxes), BEV (2D bounding boxes, top view), or 3D (rectangular cuboids).
