Reverse triangulation

[hugodwboss]

Hi there,

I am doing multiple data manipulations post triangulation and I was wondering if there is a way to then take the new 3d poses that I created and untriangulate them in 2d poses for each camera views so that I can then label the videos and visualize it in 2d.

Thanks in advance!

Hi, I recently found out that anipose has built-in functions exactly for that porpruse. You can first use anipose project-2d which allow 3D data to be reprojected back to 2D. Then you can use anipose label-2d-proj, which labels videos using the 2D reprojected data.
Hope it helps :)

Sweet! I will definitely give that a try! Thanks!

Yeah that's right! The documentation really needs an uplift based on what we built over the last 2 years.
There's also the anipose visualizer, which makes a web visualizer of your data.

If anyone else happens here for searching, you can also project 3D points to 2D using the CameraGroup.project function within aniposelib
