Radial lens distortion, circle detection, accumulation, single images


A methodology for automatic circle detection in images suffering from strong radial lens distortion is presented in this work. The automatic construction of circles from line segments is necessary to get the input data for an algo rithm for the computation of the radial distortion function. This algorithm, although already presented before, is briefly explained. Examples are given and the advantages and disadvantages of the method are discussed.
