您好,在DAIR-V2X-V数据集,通过下面的命令转为kitii格式:
python dair2kitti.py --source-root ./data/DAIR-V2X-V/single-vehicle-side --target-root ./data/DAIR-V2X-V/single-vehicle-side --split-path ./data/split_datas/single-vehicle-split-data.json --label-type camera --sensor-view vehicle

查看lable_2中的标签,比如 000000.txt
Car 0 0 0.33888581543844903 0 527.938232 69.723068 637.4556269999999 0.850836 4.337498 2.073565 -9.601712831407 0.8624079931420001 32.383280568744 1.615145

看起来转换应该梅问题的,但是,在可视化3D检测框时发现部分标签不准确,而且不准确的标签占比较大。

请问标签确实会存在偏差是吗
