Add the kitti evaluation code

[CarkusL]

I add some code to do evaluation on kitti dataset.
The evaluation code is from https://github.com/traveller59/kitti-object-eval-python.

Evaluation result

Thanks for your PR

I was using only lidar data and label data.
So, I can't achieve evaluation because I don't have calibration and 2d coordinate data.
Can you help me?

Hello, can you please tell me how can I display the Precision and Recall values, I need them for my paper, thank you.

I am using your branch, but it still only display the AP in the results, I want to display the Precision and the Recall values with the Average precision (AP)

@maudzung Hello, I found that your ImageSets files are not following the conventions in KITTI 3D, which often use 3712 pointcloud bin as train-split and 3769 as val-split. The split file can refer from OpenPCDet repo https://github.com/open-mmlab/OpenPCDet/tree/master/data/kitti/ImageSets.
