摘要: 由于鱼眼相机视场广阔在很多领域都得到了广泛应用,但其图像存在着明显的径向 畸变,需要在应用之前加以校正。为此分析了径向畸变模型解析解的非唯一性;根据径向畸变的 对称性,得出了畸变直线与理想直线之间的关系,即畸变校正的解析表达式;提出了一种鱼眼图 像径向畸变校正的新方法。实验证明,该方法计算简单,能有效校正包含直线特征的场景。

Abstract: Since the fish-eye camera has wide view field, it has been used widely in many fields. However, there is seriously radial distortion, needed to be corrected before any application. Fish-eye image geometric correction is a hot and difficult problem in current industrial applications and theoretical research. This paper presents a radial distortion model, and point out its analytical solution is not unique. According the symmetry of the radial distortion, reveals the relationship between a distortion curve and its ideal straight line, called the analytical expression of the curve distortion correction. Based on the previous analysis, this paper proposes a geometric correction method. Experiments show that this method is simple, can effectively corrects the scene which containing line features.
