Application and accuracy analysis of single lens tilt photogrammetry technology
Aiming at the limitation of 5-lens UAV photogrammetry technology in water conservancy project,the au-thors propose a 5-routes tilt measurement method with single lens UAV which permits taking pictures of water con-servancy project from multiple angles and rapid building of 3D model of the project.The errors of plane accuracy and height accuracy are analyzed,which proves the real 3D model of water conservancy project established with consumer-grade UAV under multi-routes flight scheme meets the requirements of Code for surveying of water re-sources and hydropower engineering and Specifications for the digital products of three-dimensional model on geo-graphic information.
