摘要
在研究抵偿面高程投影法、任意带高斯投影法的基础上,提出了基于最小二乘原理的具有高程抵偿面的任意带高斯投影法的新公式,并给出了其具体计算方式。通过工程实例,并与范一中、秦菊芳等学者提出的方法进行计算对比分析,结果表明,新方法能更好地满足工程需求。
On the basis of the surface elevation projection method and any band Gauss projection method, this paper puts forward a new formula based on the principle of least squares, and gives its calculation way. Through engineering practice and comparative analysis with the methods proposed by Qin Jufang and Fan Yizhong, results show that the new method can better meet the needs of engineering.
