摘要
基于无人机和3S技术,设计了综合性创新实验。该实验设计包括利用无人机生成DOM、DEM等4D产品;利用RS与GIS技术获取灾害信息及生成灾害因子图层;BP神经网络和信息量等数学模型与GIS技术相结合,评价泥石流灾害风险等内容。实践表明,通过该实验,学生们把测量学、摄影测量学、地理信息系统及遥感等专业理论知识与实验过程相结合,加深了对专业知识的理解,提高了学生的创新思维能力、专业技能及学习兴趣,该项实验还有助于提高学生毕业后的竞争力和就业能力。
Innovative practice teaching is an indispensable part of higher education personnel training system engineering,and is one of the very important teaching links.Based on UAV and 3 S technology,a comprehensive innovation experiment was designed to cultivate students’innovative practice ability.The experimental design includes using UAV to generate 4 D products such as Dom and DEM,using RS and GIS technology to obtain disaster information and generate disaster factor layer,using BP neural network and information quantity mathematical model combined with GIS technology to evaluate the risk of debris flow disaster.The practice shows that through the experiment,the students combine the professional theoretical knowledge of surveying,photogrammetry,geographic information system and remote sensing with the experimental process,deepen the cognition of professional knowledge,improve the students’innovative thinking ability,professional skills and learning interest.The experiment also helps to improve the competitiveness and employment ability of students after graduation.
