Parameter configuration，Can I set x<0

Open WSTao opened this issue 6 years ago • 9 comments

Hello, inside the code implementation, there is a parameter that is the point cloud data range, x_min=0, that is, only the target in front of the car is detected. Can you set x_min<0, so that the network can detect all targets around the car?

change point_cloud_range:[0, -39.68, -3, 69.12, 39.68, 1] to [-69.12, -39.68,-3, 69.12, 39.68, 1]

yes, but

  1. this will greatly increase inference time and gpu memory usage. be careful and consider use car_tiny to inference.
  2. the pretrained model is trained with only front area. I am not sure the performance of other area.

understand, thank you very much

@WSTao you also need to modify anchor generator params to generate anchors in other area.

Thank you very much, I still have a problem. I want to detect all the targets at once. I am now on the parameters of car, adding the categories of detection targets. How to weigh the parameters of different targets?

@WSTao Hi, Have you solve this problem of the params setting in detecting all targets around the car

Okay, thanks a lot, Do you know any ways that can transforms model trained by PCDet to ONNX file?

You can consult its author or learn about the implementation of pytorch to onnx
