| Abstract: | A optimization method for elliptic model of optical vignetting determination based on genetic algorithms is presented,and it is compared with conventional Gauss Newton optimization mothed.The result shows that the accuracy of the optimized model using Geneic Algorihms is much better than that using the conventional Gauss Newton method,and that the optimized model using Geneic Algorihms correct the shortcoming of conventianal method depending on the initial parameters near the solution. |
