Abstract:

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.
