The great advantage of this type of camera is that it offers three-dimensional information without having to resort to the classic stereoscope systems of two lenses. "These new sensors offer in-depth information, which is of great interest when working with artificial vision systems”, remarked Miguel Ángel Patricio, who coordinates this research from the Department of Informatics at UC3M. The functioning of the TOF camera is relatively simple: an infrared ring gives off a light that bounces off the body, which is then recorded and returns to the sensor. According to the time this process takes, the distance between these objects can be calculated. "Our idea”, Patricio points out, “is to be able to apply this sensor to different problems on which we are currently working, such as video surveillance systems, biometric face identification, analysis of player movement in sports performance, and man-machine interfaces”, he concluded.
