| 摘要 |
The invention relates to a motion analysis and/or tracking system including at least one camera unit (10) and trackable markers (11), said camera unit including emission detection means (19) and being arranged for generating image frames substantially including activated marker, said markers comprising means for generating a response signal to a trigger signal (25) detectable by said marker (11). Each response signal has at least a first and a second state. Said system further comprises means for detecting the positions of the response signals in each image frame, means for arranging said positions in a sorted set, means for processing the set of lists, and means to generate a unique identification code for each active marker based on the position of the response signals and state of response signals. |
