Can I reproduce your great work with MMDetection3d？ #12

Thanks for your great work! I have ever tried CenterPoint based on MMDetection3d. I wonder which parts were changed compared with the orignal CenterPoint. Looking forward to your early reply. Many thanks!

Hi, thanks for your interest in our work. Compared with CenterPoint, there are three significant changes:

  1. We modified the RPN to include features from more scales.
  2. We completely changed the detection head to separate the center classification and box regression process. The CenterFormer structure is applied after the selection of center candidates. And the regression head is now on 1D center features rather than 2D BEV features.
  3. We design a multi-frame fusion method that uses a different data processing pipeline.

Many thanks for your details! @shb9793 Hello, did you manage to get CenterFormer to work on MMDetection3d yet?

shb9793 commented 1 year ago

Not yet. But I noticed that MMDetection3d official will support CenterFormer in their framework as soon as possible.

Sounds good! But I didn't see this news in the README nor in the issues. Where did you get the information?
