Optical Stereoscopy Motion Capture System 2014

Abstract

The aim of this project is to represent a human like figure in 3D space in order to conduct motion analysis on a human subject. This document outlines the design of a motion capture system that will be used on a kayak in order to analyse the motion techniques of a kayaker. The proposed design of the system was to use GoPro cameras that were to be mounted to the kayak, in order to capture the technique of the subject. The GoPro system was successful at capturing the motion of a subject and representing the data in 3D space. Seen in the results obtained from testing against the Vicon commercial motion capture system, which was used as the control. The response from the GoPro system followed the same response that the Vicon system produced, concluding that the motion capture from the GoPro system was accurate. This was achieved by successfully: segmenting markers, 3D representation, marker tracking and depth estimation.
