传统的摄像机标定方法需要依赖空间的点对应条件或者特定的运动模式，且内外参数存在的耦合问题易引起求解的不稳定和不精确现象。非量测校正方法利用透视投影本身的几何不变特性，通过将畸变参数分离出来单独求解，较好地克服了传统方法的上述问题。这里从畸变模型、不变特征与畸变测度、模型求解三个方面综述并总结了非量测校正技术的发展现状和技术路线。

The traditional camera calibration method relies on spatial point corresponding conditions or specific movement patterns,and is easy to cause the instability and inaccuracy due to coupled problem of internal and external parameters. To solve these problems,the non?metric calibration algorithm is proposed,which takes the advantage of the geometrical invariabili?ty of perspective projection to separate distortion parameter to solve it independently. The development status and technical route of non?metric calibration algorithm are concluded from the distortion model,invariant features & distortion measure,and model solution.
