Line-based correction of radial lens distortion

A method for determining the radial distortion parameters of a camera is presented. The technique is based on the analysis of distorted images of straight lines and does not require the determination of point correspondence between a scene and an image of that scene. The method is described in detail, including information on the line detection method and the optimization procedure used to estimate the distortion parameters. Quantitative and qualitative experimental results using both synthetic and real image data show that the technique is effective. (C) 1997 Academic Press.
