Grant: Collaborative Research and Development Grants

In this research project, we propose to investigate new techniques to improve the accuracy and response time of indoor localization systems in non-ideal environments. The targeted application is the precise and continuous tracking of the position of athletes during a game or while training in various fast-paced sports. The expected improvements are such that robotic cameras can be automatically controlled in real-time to capture any individual athlete during an event. These additional cameras will provide new perspective to review some plays and could also allow fans to follow any of their favorite players on their mobile device or internet-enabled television.To fulfill the ensuing stringent requirements, new algorithms will be developed to fuse information from radiofrequency waves and accelerometers on a small electronic beacon worn by the athlete. Localization based on radiofrequency propagation already has many practical applications (GPS, cellular phone localization for emergencies, etc.) However, the current state of the research in this field is not advanced enough to accurately and reliably determine the position of a transmitting device in non-ideal conditions, for example when indoors and without a constant line of sight. This research project aims at contributing to this field by developing advanced signal processing algorithms, factoring in an accurate model of the signal propagation as well as data from accelerometer sensors. New types of antennas will also be designed, optimized for localization systems. Finally, the system will be deeply miniaturized so that it is imperceptible to the athletes.The project is proposed in partnership with Quattriuum inc., a Canadian-based company specialized in motion tracking and analysis for live performers and athletes. Their motion-tracking system is permanently installed at the Digital Imagery Research and Development Center (CDRIN) in Matane. The new techniques to be developed throughout this collaboration are expected to improve the current system's responsiveness and dynamics, thus opening new markets.
