摘要: 提出了一种可以检测并直观表示人体经络分布的实时定位和显示方法。首先,利用多通道经络阻抗检测仪和磁定位跟踪仪确定人体体表经络点的位置,获取经络点的三维信息;其次,对场景摄像机进行标定,并将其结果和经络点的三维信息通过图形变换技术变换到统一的世界坐标系下,获取摄像机的投影矩阵H;最后,根据该投影矩阵H,将经络点三维信息投影到二维图像上,形成二维经络线,并将其融合于场景摄像机拍摄的人体体表实时图像上,实现人体经络的可视化。测试结果表明,该方法能够准确有效地定位和显示人体经络。

Abstract: This paper proposed a method for locating and displaying the human meridian directly in real-time. Firstly, a multi-channel meridian impedance detector and a magnetic orientation tracker were introduced in this paper to locate the position of meridian to gain the 3-Dimensional (3D) information of meridian. Secondly, camera calibration was done for the scene camera, and then its result and the meridian points' 3D information were transformed to the same world coordinate system according to their space relative position, so that the projection matrix of camera H was obtained. Finally, using this matrix H, the 3D data of meridian points was projected onto image to form the 2-Dimensional (2D) meridian line which was matched and fused with human body image captured by the camera to visualize the human meridian. The result shows that the method can locate and display the human meridian precisely and efficiently on the actual human body image in real-time.

Key words: human meridian, graphic transformation, camera calibration, projection matrix, visualization
