虚拟现实技术在无人机航空摄影测量实验教学中的应用

航空摄影测量是一门理论性和实践性都很强的课程,实验教学在其中起着关键的作用。本文首先对该课程实验教学中存在的问题以及教学改革的必要性进行了分析,然后结合无人机航空摄影测量实习的特点,采用虚拟现实技术,建立了无人机航空摄影测量实验教学平台。对于解决实践环节中成本高、风险大、时间长、效果差等问题极具理论和现实意义,可为遥感科学与技术专业的实践教学改革提供有益的参考和借鉴。

Photogrammetry is a very theoretical and practical course, and experimental teaching plays a key role in it. This paper first analyzes the problems in the experiment teaching and the necessity of the teaching reform, and then combines the characteristics of the photogrammetry practice and advantages of VR technology to set up an experimental teaching platform for the UAV-based photogrammetry. It is of great theoretical and practical significance to solve the problems of high cost, high risk, long time and poor effect in the practice, which can provide useful reference for the reform of the practical teaching of Remote Sensing Science and technology.
