摘要：
The method for generating a representation of a dynamically changing 3D scene, comprises the steps of €¢ acquiring at least two synchronised video streams (120) from at least two cameras located at different locations and observing the same 3D scene (102); €¢ determining camera parameters, which comprise the orientation and zoom setting, for said at least two cameras (103); €¢ tracking the movement of objects (310a,b, 312a,b; 330a,b, 331a,b, 332a,b; 410a,b, 411a,b; 430a,b, 431a,b; 420a,b, 421a,b) in the at least two video streams (104); €¢ determining the identity of the said objects in the at least two video streams (105); €¢ determining the 3D position of the objects by combining the information from the at least two video streams (106); wherein the step of tracking (104) the movement of objects in the at least two video streams uses position information derived from the 3D position of the objects in one or more earlier instants in time. As a result, the quality, speed and robustness of the 2D tracking in the video streams is improved.
