Abstract

The invention discloses a space positioning device, system and method. The space positioning device comprises a communication unit for establishing communication with a positioning object; an image obtaining unit for obtaining a first stereo image of a background image under the condition that a mark point infrared light source of the positioning object is in an off state, and a second stereo image comprising a mark point under the condition that the mark point infrared light source is in an on state; an image processing unit for carrying out image processing on the first stereo image and the second stereo image to obtain a mark point light spot graph; and a positioning unit for obtaining a space coordinate of the mark point according to the mark point light spot graph. The space positioning device, system and method realize distinguishing between the object to be positioned and the background image, improve image recognition rate, reduce algorithm complexity, simplify algorithm operation environment and save cost.

Description

technical field [0001] The invention relates to the technical field of computer vision, in particular to a space positioning device, system and method thereof. Background technique [0002] Computer vision technology is a technical direction that has become increasingly mature with the development of image sensors and microprocessors recently. [0003] In computer vision technology, there is a method of reconstructing the three-dimensional information of the captured image by simulating the binocular disparity of the human eye with the left and right cameras installed at a certain distance. This method is called stereo matching in stereo vision. The disparity map is obtained mainly by finding the corresponding relationship between each image and according to the principle of triangulation; after obtaining the disparity information, the depth information and three-dimensional information of the original image can be easily obtained according to the projection model. [0004]...
