Is this possible to add a functionality for 3-D bounding box annotation? about latte HOT 5 CLOSED

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.

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

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,

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.

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