#### If your issue has not received a response for a long time, please contact the author via email at lue.fan@ia.ac.cn.
### 🔥 We release the code of CTRL, the first open-sourced LiDAR-based auto-labeling system. See [ctrl_instruction](https://github.com/tusen-ai/SST/blob/main/docs/CTRL_instructions.md).
### 🔥 We release FSDv2. Better performance, easier use! Support Waymo, nuScenes, and Argoverse 2. See [fsdv2_instruction](https://github.com/tusen-ai/SST/blob/main/docs/fsdv2_instructions.md).
