A Coding Guide to Markerless 3D Human Kinematics with Pose2Sim, RTMPose, and OpenSim

In this tutorial, we build and run a complete Pose2Sim pipeline on Colab to understand how markerless 3D kinematics works in practice. We begin with environment setup, configure the project for Colab’s headless runtime, and then walk through calibration, 2D pose estimation, synchronization, person association, triangulation, filtering, marker augmentation, and OpenSim-based kinematics. As we progress, […] The post A Coding Guide to Markerless 3D Human Kinematics with Pose2Sim, RTMPose, and OpenS
