Description

I'm trying to transform the dataset to KITTI format, but I think the ` export_to_KITTI ` file is not updated so I've made some modifications but the axis transformation part is more complicated.
Are the axis definition is the same as in NuScenes, such that for KITTI transformation we can apply ``` kitti_to_nu_lidar = Quaternion(axis=(0, 0, 1), angle=np.pi / 2) ``` ?

Research direction

Start by locating the `export_to_KITTI` file and reviewing how its axis conventions are defined. Compare those conventions with the NuScenes and KITTI representations, including the proposed Quaternion conversion; this issue is complete only when the expected transformation and any required exporter change are clearly established.
