A question about detection results which in data/KITTI/detection/

[Hichengdong]

for example,the detection results in data/KITTI/detection/pointrcnn_Car_val as follow:
0,2,298.3125,165.1800,458.2292,293.4391,8.2981,1.9605,1.8137,4.7549,-4.5720,1.8435,13.5308,-2.1125,-1.7867

1,2,356.1560,159.8431,391.7758,178.2208,1.4258,1.4772,1.5754,3.9679,-19.6023,0.4317,59.9970,1.5974,1.9132
1,2,139.4961,190.2121,223.3792,223.3236,0.7900,1.4796,1.5794,3.7088,-21.4827,2.3998,36.2672,1.7515,2.2863
2,2,294.6839,155.8907,449.7736,279.9171,8.8634,1.9858,1.7958,4.3856,-4.7726,1.7146,13.8804,-2.1411,-1.8100

I found that the 2D bbox, score, and alpha are different from the Kitti dataset. Are they projecting based on the detection results of pointrcnn? How was the score calculated?
I would like to know how to obtain the above data? Do you have any relevant code?
