How to Get Locations of the Hand Joints?

[sysu19351017]

It‘s quite cool to build a dataset in this way! I’m very interested in your work.

Now I’m trying to build a dataset according to the way mentioned in your paper “Multi-View Video-Based 3D Hand Pose Estimation”, but I’ve encountered the following problems. I hope I can get your help. I can’t get the 2D & 3D locations of the hand joints in Blender. I wonder how you achieved this in your research, which is not described in detail in the paper. Did you use a script from Blender or something else?

Thanks in advanced!

yes, you can access the bone position in a blender (3D word coordinate), and if you have the camera matrix, you can have the 3D camera coordinate and 2D location. I barely remember how I coded two years ago, but maybe using the link here, you can get an idea of how I coded then. This forum has all the hints I remember finding.

Thanks so much! I'll check the forum and have a try.
