Problems solved by technology

However, due to the neck and shoulder discomfort caused by the patient maintaining the same posture for a long time, it is easy for the patient to change the head posture, and the medical staff need to always pay attention to whether the therapeutic device and the patient's head are aligned
This method is costly, time-consuming, and has large errors. Therefore, medical staff need a fast and high-precision human head posture tracking system, which can truly feedback changes in human head posture.

Embodiment

[0130] The experimental environment of all algorithms in this embodiment: the system model is Windows7 64 bits, the memory is 8GB, the processor is Inter Core i3 dual-core 2.30GHz, and the experimental platform is Visual Studio 2012. In this embodiment, a USB camera is used to form a binocular camera to capture images. Its algorithm flow chart is as follows Figure 8 Shown:

[0131] Firstly, the binocular camera is calibrated and corrected.

[0132] After the calibration and correction of the binocular camera is completed, the image of the template pose should be collected first. The template pose should try to face the face directly to the camera lens, and the parallax of the feature point pixels on the left and right views can be obtained through ASM feature point detection. The feature point under the template pose The result is as Figure 9 shown.

[0133] Calculate the three-dimensional information of the feature points and the pose relationship of the template pose r...

Abstract

The invention discloses a human head posture tracking system for transcranial magnetic stimulation diagnosis and treatment, comprising a photographing device, a smart terminal and a computer program of a program module executed by the smart terminal; the photographing device comprises a binocular camera and a fixing device capable of fixing the binocular camera in a position where the human head can be completely shoot; the smart terminal is driven and executed by the program module of the computer program; the program module of the computer program comprises: a camera calibration module; a 3D matching module; a face detection module; and a pose estimation module. Based on machine vision technology, the camera and the computer are combined to perform measurement and tracking of the human head posture.

Description

technical field [0001] The invention relates to technical fields such as computer vision and face recognition, and in particular to a head posture tracking system for transcranial magnetic stimulation diagnosis and treatment. Background technique [0002] From the end of the 1980s to the present, computer vision has become an extremely important research field in the computer industry driven by the increasing demand for practical applications. made great progress. Binocular stereo vision is an important branch widely researched and applied in the field of computer vision. This system is a simulation of the principle of similar vision systems. It mainly uses dual cameras to obtain two digital images from different angles for the same scene, and then uses The stereo matching algorithm calculates the disparity between the corresponding image points of the two images, and combines the parameters obtained from the disparity image and camera calibration to obtain the three-dimens...
