用彩色二维编码测量动态物体三维轮廓的方法

3-D Dynamic Object Shape Measurement by Using Color-coded Method

用红绿蓝颜色的正方形组成二维编码平面 ,并将其附着在被测物体表面 ,作为立体视觉测量中的匹配点。用 2套光学成像系统获取被测物体的彩色图像 ,通过计算机图像处理技术找出 2个图像中的匹配点 ,再根据匹配点的视差来获取物体的三维轮廓信息。

A two-dimensional coding plane is made of squares with three different colors that are red, green and blue. The color squares are used as corresponding points in the stereo vision measurement by adhering than on the surface of measured object. So that we can obtain the chromatic images of the measured object by use of two sets of optical imaging systems, and find out the corresponding points of two images by use of computer image processing technique. The three-dimensional shape information of the object is based on the parallax of the corresponding points on two images. This method is most suitable for the three-dimensional tracing measurement of moving human body.
