Abstract:
Based on the analysis of nonlinear distortion of optically imaging system, a simple and effect ive dig ital method for correct ing nonlinear distort ion is proposed. T he method uses the model of radial nonlinear distort ion w ith the symmet ry of opt ical ax is to obtain correct ion coeff-i cients of the opt ical lens, and then correct s the distortion image. A simple realizat ion of softw are is discussed and the experimental results of correct ion are show n.
