摘要
通过对已有的光学非接触测量技术:光纤法、双目立体视觉法、干涉法、离焦法、轴向位移转换法和三角法的优缺点进行分析,提出采用面状条纹结构光测量人脸三维数据,采用投影仪产生的结构光场投影到待测三维人脸的表面,对观察光场进行傅里叶分析、滤波和逆傅里叶变换,从变形条纹中提取出人脸的三维信息,取得了较好的试验结果。并分析了影响实验结果的因素,得出结论:面状条纹结构光测量人脸三维数据可以达到三维人脸识别的精度要求。
Analyzed the advantage and disadvantage of the follow optics non- contact measure techniques： ray fine method, two eyes solid vision method, intervenes way, leave anxious, taxes way displacement shift method, trigonometrie method. Put forward the method of using the face stripe structure light to measure human face and get three dimension data, adopt this kind of structure light which through projecting apparatus created projection to the human face which need to measure, and analyzed the observed ray field to carry through Fourier analysis,filtration waive and Fourier transform, and distilled the human three dimension information from the distortion stripe, get the better test result. Analyzed the factors of the effect test result,and drawn a conclusion： face stripe structure light measure face three dimension data can reach the precision of the three dimension human face recognizing.
