Embodiment Construction

[0029] A non-contact positioning device using sequential illuminants of different colors provided by the technical solution will be further described below in combination with embodiments.

[0030] The present invention is implemented like this:

[0031] exist figure 1 Among them, for the image content obtained by the photographic sensor, there are two or more light sources of different colors, such as the red, green and blue three-color LED sequential light sources shown in the positioning light source ④, first set the three colors to light up sequentially It is a cycle, 20-30 cycles per second or it is adjusted to other cycle times. The red, green, and blue LEDs are lit in such a fast sequence that the naked eye can see that the light source is white or close to it because of the persistence of vision. White. Place the light source in front of the C-MOS sensor, and the sensor is set to capture images 20 to 30 times per second. At this time, in each image, different red, gr...

Abstract

The invention relates to a positioning device, in particular to a non-contact type positioning device for a lighting body capable of utilizing different color sequences, comprising a light source device, a shooting inductor, a software and hardware device processed by the shooting inductor, and connection software which is connected with a terminal device and has corresponding communication and positioning functions, wherein the light source device is a lighting source with two or more than two colors and can sequentially change a color light source, the shooting inductor is used for image interception with fixed frequency in each second, each distinct image is taken by the shooting inductor, the software and hardware device processed by the shooting inductor is used for judging if the light source device can sequentially change the color light source and the light spot positions of the color light source and is also used for eliminating the interruption of other fixed light sources, and then the software and hardware device carries out light spot coordinate operation, and then inputs light spot coordinate values to the terminal device. The invention has the advantages that the non-contact type positioning device eliminates the interruption by a changing light source when being compared with a fixed or changed background color or other interrupting light sources and precisely positions the light source position, thereby having low cost and effectively preventing the environmental interruption.

Description

technical field [0001] The invention relates to a positioning device, in particular to a non-contact positioning device utilizing sequential illuminants of different colors. Background technique [0002] At present, most of the positioning methods through photographic imaging on the market are infrared photographic positioning methods. Because infrared photography is not easy to accurately locate through natural objects such as human body temperature sensing, it is often necessary to add a so-called infrared emitter to the infrared photography sensor and then transmit the infrared light through a reflective device (such as a reflector). The light is reflected to the infrared camera sensor end. Firstly, the installation cost is relatively high, and secondly, it is still unable to block the interference of environmental heating elements. [0003] Based on the shortcomings of the above-mentioned existing positioning devices, the inventors have developed the "a non-contact pos...
