Embodiment Construction
[0025] The technical solutions of the present invention will be further described below in conjunction with specific embodiments.
[0026] like figure 1 As shown, the specific embodiment of the present invention is: provide a kind of space location method based on remote control terminal, comprise the following steps:
[0027] Step 100: Determine the reference position of the display screen, that is, determine a fixed point on the display screen as the reference position. In the specific implementation process, the frame, corner and center point of the display screen are usually used as the reference position, and on the display page, a certain point in the display may also be used as the reference position.
[0028] Step 200: emit light points to the display screen, that is, emit light to the display screen when the remote control terminal moves in space.
[0029] Step 300: Obtain the relative position of the light point and the screen content: capture the position of the l...

The invention relates to a space positioning method and a space positioning system on the basis of a remote control terminal. The space positioning method includes transmitting light to a display screen when the remote control terminal moves in space; capturing the position of a light spot of the light on the display screen, fixing the reference position of the display screen and the position of the light spot on the display screen, and computing the relative position of the light spot relative to the reference position; computing the absolute position of the light spot according to coordinates of the reference position and the acquired relative position of the light spot; and positioning contents on the display screen according to the absolute position of the light spot on the screen. The space positioning method and the space positioning system on the basis of the remote control terminal have the advantages that parameters are not required to be reset whenever the remote control terminal moves, and the remote control terminal can be positioned accurately and is convenient to use.
Description
technical field [0001] The present invention relates to a space positioning method and system, in particular to a space positioning method and system for positioning a remote control terminal at a position indicated on a display screen by moving it in space. Background technique [0002] With the development of electronic technology, the technology of the remote control terminal of electronic equipment is also becoming more and more advanced. Most of the existing electronic equipment is developing towards intelligence, especially the emergence of smart TV, which integrates the Internet and the concept of "cloud", so that the functions of remote control terminals that are required to cooperate with smart TV are becoming stronger and stronger, especially the smart TV. The remote control terminal is used as the mouse of the smart TV. In the prior art, the concept of "air mouse" is proposed for this technical problem, that is, the remote controller has the function of moving in...
