摘要
《测量学》是一门理论与实践并重的课程,针对《测量学》传统实验教学方式中存在户外实验受时空限制、测绘仪器不够先进、学生考核方式不合理等问题,以水准测量实验教学为例,利用虚拟现实技术与三维建模技术,构建了交互式水准测量虚拟仿真实验教学系统,阐述了系统的设计思路及技术实现方案。该系统通过3d Max与SketchUp软件分别对测量仪器和测量场景进行三维建模,并基于Unity平台完成虚拟测量场景的集成,利用C#语言进行系统交互开发,实现了仪器结构认知、水准测量原理及方法、水准测量演示、水准测量实训、教学反馈等一系列关键功能。此系统可为测绘学科本科教学改革提供新思路。
Surveying is a course that emphasizes both theory and practice.In view of the problems existing in the traditional experi⁃mental teaching method of surveying,such as the limitation of outdoor experiment by time and space,the lack of advanced survey⁃ing and mapping instruments,and the unreasonable assessment method of students,an interactive virtual simulation experimental teaching system for leveling is constructed by using virtual reality technology and three-dimensional modeling technology,The de⁃sign idea and technical implementation scheme of the system are described.In this system,3d Max and SketchUp software are used to model the measuring instrument and measuring scene respectively,and the integration of virtual measuring scene is com⁃pleted based on unity platform.C#language is used to develop the system interactively.A series of key functions such as instru⁃ment structure cognition,leveling principle and method,water level measurement demonstration,leveling training and teaching feedback are realized.This system can provide new ideas for undergraduate teaching reform of Surveying and mapping.
