Problems solved by technology
[0002] With the development of a variety of positioning principles and technologies, the touch function on the surface of display devices has entered our lives. The traditional keyboard and mouse interaction mode is gradually being replaced by fingers or touch pens. Positioning technologies based on various principles can be used in The surface of the display device is used to realize the touch function, but for a device with a large touch size or a high position, the user's touch range cannot cover the entire touch screen, which brings great inconvenience to the user. Therefore, the existing technology should be improved. It is necessary to provide a positioning device and positioning method that can be applied to large-size display screens, have a simple structure, low cost, and are flexible and convenient to use.

Embodiment Construction
[0024] Please refer to figure 1 It is a schematic diagram of the overall structure of the light source positioning system in the first embodiment. The positioning system 100 includes a screen 10 , an image acquisition device 20 , a light source controller 30 and a computer 40 . The light source controller 30 is used to emit light with different properties to the screen 10 in response to user selection operations. In this embodiment, the light properties include light color. Specifically, the user controls the light source control on the opposite side of the screen 10 and within the effective distance of the light source range. The sensor 30 emits light having a certain color to the screen 10 . The image acquisition device 20 is installed at a certain distance directly opposite to the screen 10 and connected to the computer 40 , and the image acquisition device 20 can capture images of the entire screen 10 . The computer is also connected to the screen 10 , and is used to det...

The invention discloses a light source type positioning system and a method thereof. The light source type positioning system comprises a screen, an image acquisition device, a computer and a light source controller. The light source controller transmits light rays to form spots with different attributes on the screen; the image acquisition device is installed on the opposite side of the screen and transmits the shot image data to the computer. The computer reads the image data and judges whether high-brightness spots exist in the image according to the brightness value; if no high-brightness spots exists in the image, the computer reads the data continuously; and if high-brightness spots exists in the image, the position and the attribute of the light spot are determined. The computer further determines the operation object corresponding to the position of the spot, executes the operation command corresponding to the attribute of the spot and controls the screen to display the execution result. The light source type positioning system transmits the light rays to the screen by using the light source controller and replaces the hands to directly touch the screen, so that the user controls the displaying of the screen within a certain distance.
Description
technical field [0001] The invention relates to a positioning system, in particular to a light source type positioning system and a positioning method thereof.
