虚实结合无人机摄影测量实验教学改革与效果评价

Reform and Effect Evaluation of Open Experiment Teaching of UAV Photogrammetry with Combination of Virtuality and Reality

为探索无人机摄影测量虚实结合实验教学模式,对无人机摄影测量实验教学存在的问题进行了分析,将虚拟仿真系统和云计算技术引入无人机摄影测量实验教学,进行虚实结合的开放式实验模式教学实践。通过问卷调查进行实验教学效果评价,问卷调查统计分析结果显示:在对照组和研究组间的累计作业时长、自主实验程度、对课程的帮助程度、兴趣度、满意度和考核成绩等调查指标存在显著性差异,虚实结合教学模式可增强实验教学效果,提高学生的研究创新和工程实践能力。

In order to explore the combination of virtual and actual experimental teaching mode of UAV photogrammetry and evaluate its teaching effect, this research analyzes the existing problems of UAV photogrammetry experiment teaching. Virtual simulation system and cloud computing technology were introduced into UAV photogrammetry experiment teaching, and the open experiment teaching practice combining virtual and reality was implemented. Experimental teaching effect was evaluated through questionnaire survey. The statistical analysis results of the questionnaire survey show that there are significant differences in survey indicators such as cumulative homework time, degree of independent experimentation, degree of help to the course, degree of interest, degree of satisfaction between the control group and the study group. The combination of virtuality and reality teaching mode can enhance the experimental teaching effect, and improve students’ research innovation and engineering practice ability.
