高程控制点 meaning in Chinese

vertical control points
verticalcontrolpoint

In the first part of this thesis , the method of data collection for building a 3d scene based on a planar vector map is studied . to the most difficult problem in data collection : the evaluation of contour line , a suit of effective automatic assisting method is advanced , which can remarkably shorten the process period and improve the efficiency of spatial data collection . the main idea of this method is " control point congregating automatically and close control point cooperating "
本文主要研究了基于二维矢量图如何获取构建三维场景所需的空间数据，包括地形、地物的二维数据采集与三维建模方法，并针对数据获取中的主要难题，即等高线高程赋值问题，提出了一种基于高程控制点自动聚集、相近控制点协作的自动处理方法，显著缩短空间数据获取的处理周期。
The intersection design is very important . but in the vertical design , the designer could n ' t use the form of contour lines to express accurately his design intension . he could only write few elevations of the pavement board corners because of the complexity in design progress and the bother in calculation
平交口立面设计，由于其设计过程复杂和计算麻烦，设计者很难以等高线等形式来准确地表达设计意图，只能是稀疏地手工计算标注若干高程控制点，设计成果对施工的指导及约束作用远不能满足要求。
