Road Engineering Measurement Based on UAV Oblique Photogrammetry and Its Accuracy Analysis
Road engineering survey is the fundamental work and important guarantee of the various stages of the planning design,construction,and operation and maintenance management of road engineering construction.Firstly,the basic characteristics of UAV oblique photogrammetry technology are summarized.Secondly,combined with practice,the application points of UAV oblique photogrammetry technology in road engineering survey are analyzed.The results show that when the UAV flies at an altitude of 80～100 m,the space distance of image control points is within 150 m,and the ground resolution is within 1.5 cm,the plane and elevation accuracy of±5 cm can be obtained by using UAV oblique photogrammetry for urban road survey.
