The invention is applicable for the remote control technical field, which provides a cursor positioning system and method, a remotely controlled device and a remote controller. The remote controller of the system comprises two infrared light emitting diodes (LEDs). The remotely controlled device comprises two infrared cameras simultaneously collecting two frames of infrared spot images formed by the two infrared LEDs, and a signal processing chip for extracting position coordinates of two infrared spots in each frame of infrared spot image, carrying out matching on corresponding position coordinates of infrared spots of the same infrared LED in the two frames of infrared spot images to acquire the current space coordinates of the remote controller, and mapping the current space coordinates of the remote controller to coordinates of a cursor on a screen of the remotely controlled device. The inventive remotely controlled device accurately positions the current space coordinates of the remote controller according to infrared light emitted from the two infrared LEDs, and makes the position of the cursor on the screen of the remotely controlled device stable.
Description
technical field [0001] The invention belongs to the technical field of remote control, and in particular relates to a cursor positioning system and method, a remote controlled device and a remote controller. Background technique [0002] With the continuous improvement of the intelligence of TVs, the applications of TVs are becoming more and more abundant. It is common to play games and browse the Internet on TVs. Compared with the rapid development of TVs, the function of TV remote control has been relatively limited. , which is mainly reflected in the fact that the interactive functions provided by traditional TV remote controls can no longer meet the increasingly complex applications on the TV side. When the user plays games or surfs the Internet through the TV, if the remote control can provide an interactive mode similar to that of a mouse on a personal computer, the ease of operation will be greatly enhanced, and the user's operating experience will be greatly improved...
