2D Motion Tracking Software

Low-Cost Motion Tracking Software

University of Alberta — Biomechanical Student Collaboration

Problem

Biomechanical students needed a motion tracking tool for analyzing joint movements. Commercial systems were expensive and required specialized hardware, limiting accessibility for research and teaching.

Approach

• Developed custom software to track 2D positions of multiple colored markers using standard video input.

• Designed algorithms to extract relative marker positions and calculate joint angles for further biomechanical analysis.

• Created a system that works with any standard camera, removing the need for specialized equipment.

Result

Delivered a low-cost, flexible motion tracking solution that supported biomechanical research and coursework. The tool allowed students to perform motion analysis with inexpensive, non-specialized hardware while maintaining useful accuracy.
