 # RTMPose3D: Real-Time 3D Pose Estimation toolkit based on RTMPose

 ## Abstract
 
 RTMPose3D is a toolkit for real-time 3D pose estimation. It is based on the RTMPose model, which is a 2D pose estimation model that is capable of predicting 2D keypoints and body part associations in real-time. RTMPose3D extends RTMPose by adding a 3D pose estimation branch that can predict 3D keypoints from images directly.
