Abstract
UAV aerial survey technology has the advantages of high efficiency,flexibility and high precision in large-scale topographic surveying and mapping,and is able to significantly improve the efficiency and ensure the accura-cy of the surveying and mapping results.By equipping with high-resolution optical cameras and LiDAR,UAV can quickly obtain the image data that meet the accuracy standards of scale topographic maps.In actual large-scale top-ographic mapping,in order to reasonably apply the UAV aerial survey technology,the surveyors should scientifical-ly set up the image control points and plan the flight routes.This article focuses on analyzing the technical features and application key points of UAV aerial survey in large-scale topographic map surveying and mapping.关键词
