Abstract

The invention discloses a handheld controller, and a tracking and positioning method and system. The handheld controller includes a handle and a bracket. The handle includes an input device for receiving an input operation of a user. The bracket is connected to the handle, and the outer surface of the bracket has an identification pattern. In the tracking and positioning method, an imaging deviceacquires an image of an identification pattern; and a terminal device performs tracking and positioning on the handheld controller according to the identification pattern. The tracking and positioningmethod and system can realize tracking and positioning of the handheld controller by setting the identification pattern on the handheld controller. Compared with the prior art, the tracking and positioning method and system do not need to accurately control the frequency of strob of light spots, are simpler in the structure, and are lower in the cost. In addition, the tracking and positioning method and system can further reduce the control demand for the imaging device, and do not need to specifically adjust parameters of the imaging device to match tracking and positioning of the active illumination handheld controller.
