非接触式人体测量中的图像畸变校正方法

Image Rectification of Geometry Distortion in Non-contacting Body Measurement System

分析了光学成像系统产生几何畸变的原因,并根据光学成像原理提出了图像校正的数学模型和方法.通过实验对摄取的数字图像进行透视和几何畸变校正,确定对应元进行三维重建,获得了人体特征线的有效信息。

Optical imaging errors causing the non-linear geometry distortion are analyzed. The mathematic model and the method for image rectifying are given according to the principle of optical imaging. The digital images are taken to the perspective and the geometry distortion of it is rectified, thus determining the parallelism member to be 3-D reconstructed and obtaining the effective information of the body characteristic curves.
