摘　　要：本文研究了一种新的人体非接触测量方法--投影条纹相位测量法.采用一般的白光照明,将光栅投影到人体表面,用掇象机将所形成的变形栅摄入计算机内的图象帧存贮器内,利用移相算法或付立叶变换法可以计算出图象上每个象素点的相位,进而可以计算出每个象素点的三维坐标以及人体的三维尺寸.This paper discusses a new method for non-touching measurement of humanbody,which is called projection fringe method.With general white light diverging illumina-tion,a sinusoidal grating structure is projected onto body to be measured,and the resultingdeformed grating image is detected by a video camera and processed by a microcomputer.The phase of every pixel in the grating image can be determined accurately by shiftingphase method or Fourier transform method.So,the measurements of the human body canbe obtained.
