摘要
结合二次曲面与半参数模型以及最小二乘配置方程,介绍了基于二次曲面的半参数模型的方法,并用实测数据验证了该方法较经典二次曲面的有效性。通过算例分析,得出该方法可应用于河道断面测量中。
Combining quadric surface with semi-parametric model and least square collocation,we introduced the semi-parametric model based on quadric surface and proved its validity by a set of measured data.In hydrographic surveying,with this new method,leveling is not necessary to be provided that there are certain count of bench marks and they are well-distributed.
