OpenCap: 3D human movement dynamics from smartphone videos
OpenCap is an open-source cloud based tool that enables users to perform 3D motion capture using two smartphones. Videos are processed automatically in the cloud to produce a scaled OpenSim model and compute inverse kinematics. Data can be downloaded for additional analysis or to generate muscle-driven simulations to study underlying loads, such as muscle forces and joint loading during motion. The paper was published on PLOS Computational Biology in October 2023.
