Abstract
A system and method for human motion detection and tracking (10) are disclosed. In one embodiment, an optical sensing instrument (16) monitors a stage (24). A memory (182) is accessible to a processor (180) and communicatively coupled to the optical sensing instrument (16). The system (10) captures a depth frame (150) from the optical sensing instrument (16). The depth frame (150) is converted into a designated depth frame format (152), which includes at each image element second coordinate values relative to the depth frame (150). Probability distribution models are applied to the designated depth frame format (152) to identify a respective plurality of body parts. The position of each of the respective plurality of body parts in the designated depth frame format (152) is calculated as is the position of each of the respective plurality of body parts in the depth frame (150).
