Abstract: In the paper principle and models are introduced about nonlinear distortion in imaging with optical camera lens in computer vision. It puts forward main distortion reason which is inaccuracy of axis distance of lens. Four slaving methods of nonlinear distortion parameters are viewed. Contents and feature of the methods are introduced,categorized and compared with. Some problems are discussed when they are used to practice.
