12. Accuracy in building maps using Unmanned Aerial Vehicle (UAV) data

Abstract

Unmanned Aerial Vehicle (UAV) is the technological advancement that invented about half a century ago. It is widely applied in defense and other sectors, obtaining many remarkable results in the world as well as in Vietnam. This study evaluates the accuracy of UAV image measurement with influence factors, including shooting altitude, camera parameter, photographic coverage, software and application algorithms for image processing, density and distribution of ground checkpoints, and topographical features of the measurement area. This paper presents results of the influence of the above factors on UAV image analysis, and then proposes appropriate solutions for improving the accuracy and cost-effective use of UAV in building maps.
