【Abstract】 The development of new basic surveying and mapping has driven the innovation of quality inspection technologies.This paper aims to study the technology of acquiring quality inspection data for new surveying and mapping products without ground control points based on a new-type surveying and mapping equipment-the unmanned aerial vehicle(UAV)aerial photography system.Based on the relevant research achievements of the UAV aerial photography system and the standards related to aerial photography, this paper discusses the quantitative relationship between aerial photography flight parameters and the data accuracy of surveying and mapping products, and presents the corresponding mathematical model.At the same time, it analyzes three modes of GNSS-aided UAV aerial photography, and designs a ground control point-free UAV aerial photogrammetry scheme for acquiring data used in quality inspection of large-scale surveying and mapping products.The feasibility of the scheme combining the flight parameters designed by the mathematical model with GNSS-aided UAV aerial photography has been verified through the experiment in Luoding, Guangdong, which can obtain high-precision quality inspection data corresponding to the scale.更多还原
