Abstract

Analyzing the image geometrical distortion error with mathematical model and its effect on image matching registration. Researching two geometrical correction methods: perspective transformation and affine transformation. Presenting the method of estimating geometrical distortion parameters with the two transformations and the geometrical correction method of distorted image with the estimated parameters. The experiment shows the two methods are practical to image matching. Besides, paper presents some geometrical correction principles.
