A motion analysis system for tracking the motion of one or more light-emitting markers attached to an object includes at least one camera for recording a series of image frames, and at least one light source in communication with said at least one camera for generating optical trigger signals. Each of the light-emitting markers includes a sensor for detecting the optical trigger signals generated by the at least one light source. Each light-emitting marker also includes one or more light-emitting elements for generating optical response signals after the sensor detects the optical trigger signals, the optical response signals having a first state and a second state being recordable by the camera as a series of image frames. The system also includes a detector for detecting the positions of the optical response signals in each recorded image frame, an arrangement mechanism for arranging the detected positions of the optical response signals in a sorted list, a processor for processing the sorted list and a generator for generating a unique identification code for each light-emitting marker based upon the optical response signals and the state of the response signals in the sorted list. |
