Embodiment Construction

[0070] The present invention is further analyzed below in conjunction with specific examples.

[0071] Such as figure 1 The acupoint positioning system based on the combination of binocular vision and coded structured light, including two left cameras 1 and right cameras 3 with the same parameters, a structured light generator 2, a support frame 4, a calibration board, and a main controller; two cameras, The structured light generator is located above the support frame, and the structured light generator is located in front of the two cameras;

[0072] The structured light generator is used to project structured light on the back of the human body; wherein the pattern of the structured light is as follows figure 2 Stripe pattern with Gray code encoding;

[0073] The camera is used to capture the image of the back of the human body projected with a structured light pattern;

[0074] The calibration board is used for camera calibration;

[0075] The main controller is used ...

Abstract

The invention discloses an acupoint positioning system and method based on combination of binocular vision and coded structured light. The method comprises the following steps of performing three-dimensional reconstruction on the human body back model, restoring two-dimensional coordinates shot by the camera into three-dimensional coordinates in a world coordinate system, segmenting the human bodyback model from the image, and finding out corresponding acupoint information of the human body back in combination with traditional Chinese medicine. The two cameras and the structured light are adopted to reconstruct the three-dimensional information of the back, and the positioning accuracy is further improved. Coding structured light and binocular vision are combined, the problems of indoor white walls and texture-free objects are effectively solved, the environment interference resistance is enhanced, the reliability is higher, and the depth image quality is greatly improved.

Description

technical field [0001] The invention belongs to the field of medical technology applications, and in particular relates to an acupoint positioning method based on the combination of binocular vision and coded structured light. Background technique [0002] In traditional Chinese medicine, acupuncture and moxibustion have a long history and unique curative effects. However, this treatment method requires a higher level of practitioner experience and techniques, which is specifically reflected in the accuracy of acupoint positioning. The body-based acupoint positioning method given in medical books is mainly based on a certain organ or a certain characteristic part of the body to find the relative acupoint position. At present, the relevant technologies of automatic acupoint selection at home and abroad are still immature, most of them are in the research stage, and there are almost no examples of clinical application. It takes many years of clinical practice to accurately d...
