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。
In order to realize fast high-resolution scanning imaging of human face, a three-band laser three-dimensional face scanning method is proposed. The method uses three parallel and equidistant line structured light as the illumination light source, and the image sequence is obtained by scanning the human face. The three light bands are grouped according to the position correlation of the light bands in the adjacent images, and the three-dimensional point cloud of the human face is obtained through the calibration matrix. Fitting points to cloud and sub-sampling to obtain uniform data. Experimental results show that this method is a fast and effective three-dimensional measurement method.
