| 摘 要： | 介绍平面坐标转换的仿射变换和二次多项式变换法,这两种方法存在一定的不足,为了提高转换精度,提出"仿射变换+神经网络"的混合模型法。通过工程实例,比较发现混合模型比前两种模型的计算精度高,证明该方法的有效性,并得到具有工程应用价值的结论。

| Abstract: | The method of affine coordinate transformation and the method of quadratic transformation used for on plane coordinate transformation are briefly introduced.The two methods above have shortcomings.In order to improve the accuracy of transformation,an omnibus model combining a BP Neural Network with affine transformation model is put forward.Through the practice of the project,we could find the omnibus gets more precise results,the validity of the method used for transformation is validated,and some conclusi... |
