无人机倾斜摄影技术在工程制图教学中的应用研究

Study on the Application of Oblique Aerial Photography Technology Using Drones in Engineering Drawing Education

摘要: 针对传统工程制图教学空间认知培养困难、实践效率低、与行业数字化脱节等问题，本文将无人机倾斜摄影技术引入课程，构建“数据采集–模型重建–制图表达–软件协同”一体化教学模式。并基于建构主义与项目式学习(PBL)理论，设计对照教学实验，以空间认知测试、制图技能考核、作品量化评分与学习问卷开展实证对比。结果表明：学生的空间认知、制图精度与学习效率得到明显提升。同时，文章提出开源软件替代、设备共享、云端计算、标准化师资培训等可落地方案，可为工程制图数字化教学改革提供参考。

Abstract: Traditional engineering graphics teaching faces difficulties in spatial cognition training, low practical efficiency and disconnection from industrial digitalization. This paper introduces UAV oblique photogrammetry to build an integrated teaching mode of data acquisition, model reconstruction, graphic expression and software collaboration. Based on constructivism and PBL theory, a comparative teaching experiment was conducted via spatial cognition tests, drawing assessments, work scoring and questionnaires. The results show that the approach significantly improves students’ spatial cognition, drawing accuracy and learning efficiency. Feasible measures including open-source software replacement, equipment sharing, cloud computing and standardized teacher training are proposed to support the digital teaching reform of engineering graphics.
