Is this possible to add a functionality for 3-D bounding box annotation?

Dear Bernwang,

The tool works flawless, Thank you very much for your work! I am wondering if it is possible to add a functionality to do 3-D bounding box annotation? Specifically, the ability to specify the ground level and the height of the object?

Hi zhou-git,

I apologize for the late response. There has been a lot of work on the annotator that I am excited to push. One of the features is to add 3D bounding box annotation. I am thinking of automatically extracting the height of the bounding box after drawing a 2D bounding box. Do you think you would prefer that over manually specifying the height of the object?

Thanks, Bernie

Hi Bernie,

It is great that you still works on this project! Automatically extracting object height seems interesting but I not sure about the precision, which is very important to manual annotations. A typical case is like annotating a car with no points available on the wheels, then it becomes tricky to determine the ground plane of that 3D box. I kind of thinking that a easy to use interface is most important for a manual annotation tool in the first place. But of cause it is a open-source project, so it may be too much to ask.

Best, Jin

Hi Bernie,

Thank you very much for your talented original work. I found that the most helpful open source project. I am also interested in having that 3D bounding box annotation feature and I think the automatic annotation bounding box would be enough for now. If we can manually adjust it would be better, but I really understand that you are pretty occupied by your own work and you have very litter time for that.

I have developed myself. If you want to use it, please find it at https://github.com/songanz/LiDAR-annotator

Hi Jin @zhou-git but the ground plane will just be the lowest Z point possible because the car wheels always touch the ground?
