Abstract

The invention provides a three-dimensional space positioning system based on infrared image recognition. The three-dimensional space positioning system based on the infrared image recognition is used for recognizing the three-dimensional space position of a target object and comprises a first infrared camera, a second infrared camera, a third infrared camera, an infrared laser device, a projection screen and a computer, wherein the image plane of the third infrared camera faces towards the direction of the projection screen, the image plane of the first infrared camera and the image plane of the second infrared camera face towards the direction of the target object, the optical axis of the first infrared camera and the optical axis of the second infrared camera are strictly perpendicular to the projection screen, the infrared laser device is arranged at the position of the target object and points to the position of the projection screen, and the computer is connected with the first infrared camera, the second infrared camera and the third infrared camera. The three-dimensional space positioning system based on the infrared image recognition has the advantages that the target object is identified according to the infrared laser device, positioning is carried out through the receiving of the infrared cameras, and thus the three-dimensional space positioning system based on the three-infrared-camera positioning technology is provided. Through the visualization operation carried out on complex data through the computer and a real-time interaction environment, vivid three-dimensional visual perception is achieved, and the real-time capture of motion is achieved.

Description

technical field [0001] The invention relates to the technical field of image recognition, in particular to a technology for locating infrared light spots in three-dimensional space. Background technique [0002] In prior art methods, three-dimensional spatial positioning technologies mainly include electromagnetic and optical methods. The electromagnetic method uses the spatial magnetic field to collect the electrical parameter changes of the object's motion and analyze the motion characteristics, but the magnetic field is easily disturbed and has high requirements on the environment. The optical three-dimensional space positioning technology analyzes the motion characteristics of objects through optical and image processing technology, and can capture the real-time motion of the positioning object, but the computational workload of positioning the motion characteristics of the object is relatively large. [0003] The method of using two cameras to realize the three-dimensi...
