在自动图像拼接中，图像模型参数的求取和优化是一个最小二乘问题。本文提出基于Levenberg-Marquardt算法的图像拼接参数求解算法，通过建立适当的图像相机参数模型，并将图像模型参数的优化问题转化为图像之间映射误差的最小二乘问题，解决了图像配准参数的求取问题。通过利用求得的图像参数把图像映射到球面上，使用图像渐进混合和双线性插值绘制球面，并对球面进行展开，最终生成平面拼接图像。

In automatic image stitching, the solving of the image model parameters and optimizat ion is a least squares problem. This paper presents the solution algorithm based on Levenberg- Marquardt algorithm for image stitching parameters. Through the establishment of appropriate i mage camera parameter model, the image model parameter optimization problem becomes a lea st squares problem for the mapping error between the images and to solve the problem of the i mage registration parameters. With the images mapped to the sphere through the use of the im age parameters obtained, the progressive mixing of the image and bilinear difference to draw th e spherical surface, the final plane mosaic image is generated
