About ver2 in code about radar_depth HOT 2 CLOSED

Upon further inspection it seems that the error occurs when the there are too few points(1 or 0) in input_data['radar_points']. Could you suggest a fix to this?

Hi @isht7

The ver2_lidar1_radar3_radar_only is more like a patch for more radar information. In ver3, if I remember correctly, I used only the front and back camera + Radar points, but we accumulate the radar points along the temporal axis a bit to get more points.

Regarding the ver2 issue, as I indicated in README.md, I haven't finished the documentations on dataset yet. The processed dataset was originally extracted from the nuScenes database. The code used to export them can be found here. However, I haven't tested them before the release of the code (I don't have the machine and storage to do that now since students need to leave the lab after the project). The top priority in this repo is that the users can used the training code and processed dataset to get the similar results I got on the paper.

Regarding the projection of radar points onto other camera, you can check the code here and try it yourself. I remember that you can't get like more than 10 points which is quite frustrating. That's the reason why I changed back to front + back views.
