The invention discloses an unmanned aerial vehicle video
augmented reality implementation method based on a
photogrammetry technology and a 3D GIS technology. The method mainly comprises the steps ofvideo frame extraction, camera calibration, aerial
triangulation reconstruction, 3D GIS virtual scene establishment, sequence frame image rendering, video synthesis and the like. According to the invention, the POS data of the unmanned aerial vehicle are utilized; the accurate camera track and attitude are recovered by using a space three-adjustment method; A three-dimensional geographic scene isestablished in a 3D GIS
system; The method comprises the steps of acquiring a
video image, superposing various types of vector data, importing a three-dimensional model, adding a custom character
label and a graphic
label, realizing a blanking effect by importing a
digital surface model, then acquiring a rendered image with the same
visual angle as the original video frame by frame, superposing the rendered image with the original video frame by frame, and acquiring a video result containing rich information. According to the method, the
processing efficiency and effect are improved, the
automation degree can be greatly improved in repeated line inspection application of linear
engineering, and an efficient and real technical means is provided for scheme display and on-site inspection.
