Application of UAV Tilt Photography Modeling Technology in Campus Pipeline Network Project
For a long time,the later maintenance of the park pipe network has the problem of focusing on construction and neglecting maintenance.In view of the industry problems and comprehensive innovative technologies,this paper proposes a new idea of high-precision modeling based on UAV oblique photography technology,combined with GIS technology,and the connection with BIM pipeline model to realize the visual-ization of park pipe network governance,analyzes the key technical processes and urgent problems to be solved in the process of oblique photography data acquisition,processing and fusion loading,and discusses the implementation methods of high-precision model.The research work completed the high-precision real-world 3D modeling of the Zhengdong Campus of Henan University of Economics and Law.The image acqui-sition was carried out by using the DJI Matrice 300 professional drone to plan an inclined wraparound route.The image is processed by using the triangulation method,the image inpainting method of the improved GAN network and the adaptive light spilting processing method,and the high-precision point cloud is generated by a special algorithm,and the error in the calculation is corrected,and the image scale is accurately controlled,so that the generated model is more accurate and more detailed.
