A Simple and Effective Correction Method for Distorted Image from Camera Lens System

This paper proposes a simple and effective correction method for the distortion of the picture which came from the distortion of the spherical lens and the state that real image plane and picture image plane are not horizontal. Even though there are many algorithms that corrects for the distortion of the lens, most of the algorithms are modeling lens, take a method to find a proper parameters. This demands time delay depends on the degree of modeling and the amount of calculation. In addition, most of the algorithms is processed with condition that lens is fixed in center of image and a picture image plane and a real image plane are horizontal. Thus, in a system which needs real time image processing such as movable robots, more effective and simpler algorithm is necessary because the amount of the calculation becomes problematic in system. Furthermore, when a robot in motion intent to get data on real image place, where picture plane and real image plane are not horizontal it could be a problem. Therefore, when the distortion of image which occurred from the distortion of the spherical lens, real image plane and picture plane are not horizontal, this paper suggests more effective and simpler algorithms, which corrects for the distortion of the lens with kinematics without modeling
