摘要
回顾了测绘工程专业核心课程《误差理论与测量平差基础》(简称《经典平差》)教学改革主要成果特点,分析指出了现有教材以高差、边长和角度一维观测值为主要研究对象存在的不足,并在此基础上系统探究了二维和三维坐标观测值的点线面测量平差问题。通过5类二维和5类三维坐标观测值的单元整体教学设计,更新了平差模型教学案例并丰富了平差模型属性数据内涵,从而为解决本课程体系“存量更新、增量补充”提供一定参考。
The achievements of teaching reform and its main characteristics were reviewed for"Error theory and Foundation of Surveying Adjustment"(short for the classical adjustment)which is one of the core courses at the surveying and mapping engineering major,and it was pointed out that the existing teaching cases mainly focused on the one-dimensional observation values of height difference,side length and angle measurements.Then,the point-line-plane-volume surveying adjustment problem with two-dimensional and three-dimensional coordinate measurements was systematically investigated in this paper.Through the unit overall teaching design of the 2D and 3D coordinate measurements,five kinds of 2D and five kinds of 3D coordinate measurements equations were constructed in detail,and the connotation for the number of redundant observations in the adjustment model were enriched.Thus,it provided important teaching design cases for aiming at both existing updating and incremental supplement of the classical adjustment.
