Abstract
This paper describes a method to correct lens distortion for digital cameras. A simple but effective distortion model using local spatial transformation will be used. In addition, the effect of effective focal length on the distortion model will be considered, and we will discuss how to introduce this factor to enhance the model. Finally we have some theoretical analysis and experiments demonstrating that the correction improves the accuracy of image stitching.
