Apply for this job Hourly · $15/hr

This is a 2-hour pilot project for annotating 3D poses based on 2D annotations. Successful completion may lead to ongoing work, with flexible scheduling available.

The goal is to achieve accurate 3D key points by refining positions, depths, and orientations. Steps include validating annotations, adjusting 2D key points and visibility, estimating FoV and ground planes, and aligning key points with an avatar model. Tools like Undo/Redo assist in making precise adjustments throughout.
