摘要
为实现人脸的快速高分辨率扫描成像,提出了一种三光带激光三维人脸扫描方法。该方法采用三条平行且等间隔的线结构光作为照明光源,通过对人脸进行扫描得到图像序列。根据相邻图像中光带的位置相关性对三条光带进行分组,通过标定矩阵得到人脸的三维点云。对点云拟合并二次采样后得到均匀数据。实验结果表明,该方法是一种快速有效的三维测量方法。
Abstract
A three-line structured light three-dimensional (3D) scanning method is proposed in order to achieve the purpose of measuring human faces in high resolution rapidly. Three parallel structured light strips with the same distance are projected on the human face to obtain scanning image sequences. In accordance with the location relationship of light strips between adjacent images, three light strips are grouped. Combining with the calibration result, point cloud of the human face is gained. Then, the original point cloud is fitted and resampled to obtain uniform data. Experimental results show that this method is a rapid and efficient 3D measuring method.
