| 摘 要： | 通过双目视觉原理构成脉搏图像传感器采集脉搏薄膜图像。对系统摄像机采用张正友标定方法，得出系统结构参数建立的物空间坐标到像平面坐标对应矩阵。再基于SIFT特征算子进行左右2幅图像匹配，得出2幅图像一一对应的特征点。最后根据双目视觉原理得到特征点的三维信息。

| Abstract: | Based on principle of binocular vision,the images sensors are applied to capture the pulse images.Using the camera calibration method of the Zhengyou Zhang to get the structure of the system parameters,a projection matrix for stereo vision measuring model is chieved.Based on SIFT features matching,the left and the right images are matched together and the feature points of two images are got.At last,we got three-dimensional information of feature point according to the principle of binocular vision. |

| Keywords: | binocular vision pulse images feature matching 3-D information |
