摘要
大地测量学中存在大量理论性和实用性强、公式形式繁琐冗长且精度要求较高的计算问题,其相关教学内容复杂抽象,是课程教学的重点和难点,常规教学方法课堂效果差。为此,利用MATLAB GUI工具设计开发了大地测量计算实验系统,包括地球椭球与测量计算、高斯投影及其计算、大地测量坐标系统的转换等模块。该实验系统操作简便、交互性良好且可扩展性强,可为教师在课堂教学中进行算法演示,也可用于学生开展自主学习和创新性实验。教学实践表明,所开发的实验系统可以提高授课效率,激发学生的学习兴趣,使学生加深对理论内容的理解,对培养学生的工程实践能力具有显著作用。
,which is the focus and difficulty of course teaching.Conventional teaching methods have poor classroom effects.To solve these problems,we used MATLAB GUI tools to design and develop a geodetic computa-tional experiment system,including the earth ellipsoid and measurement calculation module,Gaussian projection and calculation module and geo-detic coordinate system conversion module.The system is easy to operate with good interaction and strong scalability,which can be used to dem-onstrate algorithms for teachers in classroom teaching,and can also for students to carry out independent learning and innovative experiments.Teaching practice shows that the developed system can improve teaching efficiency,stimulate students’interests in learning,deepen the under-standing of theoretical content,and have a significant effect on cultivating students’engineering practice ability.
