Correction Optimization of Lens Radial Distortion with Bending Measurement Function

摘要

In this paper, a distortion correction method with reduced complexity is proposed. With the single-parameter division model, the initial approximation of distortion parameters and the distortion center can be cali-brated. Based on the distance from the image center to the fitting lines of the extracted curves, a bending measure-ment function with a weighted factor is proposed to optimize the initial value. Simulation and experiments verify the proposed method.
