测量教学无人机的设计与应用

无人机测量已经融入了测绘行业的方方面面,也是测绘行业发展的重点。由于测量无人机产品昂贵、校园场地限制、维护复杂及飞手训练成本高等原因,无人机测量在教学上一直处于空白阶段。本文重点分析了校园地理环境和电磁干扰等情况,对无人机的飞行平台、航电系统、航摄系统、系统软件进行了研究和分析,设计了教学测量无人机。对航空摄影测量、空三测量等教学测量试验进行了测试,并对测试数据进行了验证分析。本文设计的测量教学无人机在进行1∶2000的空三测量,所测的数据误差符合国家标准;摄影测量获得的航片,通过Pix4D软件的处理生成了点云图、数字表面模型和正射影像图。本文研究有效解决了无人机测量在教学上的应用,为无人机教学测量设备和试验教学的研究提供了技术参考。

Design and application of survey teaching UAV

The survey of UAV has been integrated into all aspects of the surveying and mapping industry, and is also the focus of the development of the surveying and mapping industry. Because of expensive measurement UAV products, limited campus site, complex maintenance and high cost of flying hand training, the teaching of UAV is still blank. This paper focuses on the analysis of campus geographical environment and electromagnetic interference. The flight platform, avionics system, aerial photography system and system software of UAV are studied and analyzed, and the teaching and measuring UAV is designed. The teaching measurement experiments such as aerial photogrammetry and space-three measurement are designed and tested, and the test data are verified and analyzed. The measurement teaching UAV designed in this paper is carrying out the space three measurements of 1:2000, and the error of the measured data is in line with the national standard. Aerial photographs obtained from photogrammetry are processed by Pix4D software to generate point clouds, digital surface models and orthophoto images. The research in this paper effectively solves the application of UAV measurement in teaching, and provides a technical reference for the research of UAV teaching measuring equipment and experimental teaching.
