| 摘 要： | 从立体图像对中获取精确的三维信息需要进行相机建模、标定和图像点的匹配［１，２］．提出了特征点的选取；利用金字塔图像结构进行立体匹配，以及对匹配点进行整体性检验的准则。实验表明，该算法匹配速度快，错误概率小，匹配点在整个景物中分布均匀。

| Abstract: | In order to accurately extract three-dimensional informadon from a pair of stereo im-ages,camera modelling,calibration and matching of the image points are required.The se-lection of feature points and the application of the pyramid image structure in stereo matching are discussed.A criterion for checking the globality of the matched points is proposed.Experiments show that the algorithm proposed is of high speed, low error probability andthe matched points are distributed uniformly in the scene. |
