By modularizing different techniques for Find instances of a single model or 2. Estimating 3D human pose from monocular image or video is an ill-posed problem that can benefit from prior constraints. We take 2D images as our research object in this paper, and propose a 3D pose estimation model called Pose ResNet. The 3D pose estimation datasets need to be prepared in a laboratory environment using motion capture systems [48]. In particular, it involves the estimation of human key point trajectories in a 3D space.

The ambiguities in estimation of 2D and 3D poses of multiple persons can be verified by using multi-view frames, in which the occluded or self-occluded body parts of some persons might be visible in other camera views. In the last chapter, we developed an initial solution to moving objects around, but we made one major assumption that would prevent us from using it on a real robot: we assumed that we knew the initial pose of the object. In contrast, optimization-based methods fit a parametric body model to 2D features in an iterative manner. The significance of 3D-HPE lies in its broad range of applications, including action recognition [1, 2], sports analysis, and healthcare [3, 4].
