By using calibrated image, it can measure plane absolute displacement of worktable automatically via feature point extraction and gray vector matching.
该方法采用事先通过标定的图像，对自然标志(特征点)的提取和基于灰度向量匹配来完成绝对位移的测量。
Based on this model, the 3-D digital image can be calculated by computing the lateral displacement of the same point on the two point-array images.
依据此模型，通过计算相对应点在成像平面上的横向位移，可计算出物体的深度图像。
