twisted smpl occuring

[skcskc7]

hi

I have 30 cameras as input datasets and face twited smpl results in some frames.

Actually, I am using easymocap 0.1 version, and in your last issue, I confirmed that it was solved in 0.2 version.

Can you point me to the part of the code where the twisted smpl problem is resolved?

Hello, have you tried the latest version? We keep the same data structure. You can just pull and run it with the same dataset.

I have the same issue with the newest code (apps/demo/mv1p.py, 4/10/2023, commit: 26d07c2), any update on this?

I guess this issue comes from that: when you take numerical average between two rotations (177 and -179 degree), you will get -1, while the correct answer should be 179. Here is a solution to this kind of problem: https://stackoverflow.com/a/30129248

Here is a fix. I'm testing the code and will submit a pull request if it solves the issue. Hopefully this will also fix issue #109 #110
Seems that only modifying the interp function doesn't fix the issue.

Run newest code as this.
We don't use interp now.

Run newest code as this. We don't use interp now.

It's not working, this is what I got:

Here is how I run the code, let me know if there is anything wrong I did:

1. copy-paste the images folder, intri.yml and extri.yml from my old dataset
2. run openpose: python3 apps/preprocess/extract_keypoints.py ${data} --mode openpose --openpose ${openpose} --hand --face
3. run python3 apps/demo/mocap.py ${data} --work lightstage-dense-smpl --subs_vis 0 1 2 --ranges 0 800 1

I can share my dataset if that helps
