A computational method to track and reconstruct the movements of a cloud of independent markers in optical motion capture systems without using a human skeletal model

Human motion capture has been widely used in many application areas. In movies and games, this technique is frequently employed to animate virtual characters. In sports, motion capture and analysis focus on optimizing movements of athletes and injury prevention. Other applications areas include medicine, military and engineering. Motion capture can be accomplished by several technologies. However, optical marker-based systems are considered the gold standard of the motion capture field. They can offer high precision levels and flexibility to support most applications, but they are also the most expensive systems due to high costs of hardware and software. Although low-cost optical systems have been proposed in the last decade, these systems cannot provide enough precision, flexibility, automatism and/or real-time capability for a number of applications. This project aims to develop a complete and high precision approach to track and reconstruct the movements of a cloud of independent markers, in real time, using either multiple infrared specialized cameras or a group of low-cost consumer cameras, such as those available on mobile devices.

A real time approach to calibrate a set of video cameras for motion capture systems using a calibration wand

In the context of motion capture technology, camera calibration is the process of finding intrinsic and extrinsic camera parameters. The intrinsic parameters are related to internal aspects of the camera, like focal length, principal point and distortion coefficients. The external parameters tell us about the position and orientation of the camera itself with respect to a reference coordinate system. This project proposes the development of a real time approach to calibrate a set of low-cost video cameras for motion capture systems using a calibration wand.

A specialized motion capture system for real-time analysis of mandibular movements using infrared cameras

In the last years, several methods and devices have been proposed to record the human mandibular movements, since they provide quantitative parameters that support the diagnosis and treatment of temporomandibular disorders. The techniques currently employed suffer from a number of drawbacks including high price, unnatural to use, lack of support for real-time analysis and mandibular movements recording as a pure rotation. In this project, we proposed a specialized optical motion capture system, which causes a minimum obstruction and can support 3D mandibular movement analysis in real-time. A few specialized algorithms have been developed to automatically recognize our set of markers and track them along a motion capture session.
