英文摘要 | This paper describes a method for correcting lens distortion for digital cameras. A simple but effective distortion model using local spatial transformation was used. In addition, the effect of the effective focal length on the distortion model is considered, and we discuss how to introduce this factor to enhance the model. Finally we present the result of theoretical analysis and experiments demonstrating that the correction improves the accuracy of image stitching. |
