An image correction-based approach to camera calibration

In several cases, the lens distortion introduces some error to visual detection. It is necessary and significant to correct the error efficiently for the purpose of extracting the accurate position information of the observed object.

Description
Summary:In several cases, the lens distortion introduces some error to visual detection. It is necessary and significant to correct the error efficiently for the purpose of extracting the accurate position information of the observed object. We developed a new method for correcting the radial lens distortion based on the pin-hole model with first order radial distortion. The development of the method is motivated through a desire to develop a linear camera calibration technique that requires the calibration of the less extrinsic parameters, and has better real-time character. Both the simulated image and real image are given to denote that this correction method is robust and accurate.
