隨機抽樣一致算法（RANdom SAmple Consensus,RANSAC）。它採用疊代的方式從一組包含離群的被觀測數據中估算出數學模型的參數。 RANSAC是一個非確定性算法，在某種意義上說，它會產生一個在一定機率下合理的結果，而更多次的疊代會使這一機率增加。-Ransac algorithm (RANdom SAmple Consensus, RANSAC). It uses an iterative way to estimate the parameters of the mathematical model　a set of observed data contains outliers in. RANSAC is a non-deterministic algorithm, in the sense that it will produce a reasonable result in a certain probability, and iterative more times will increase the chances.
