| Abstract: |
| The real 3D scene can truly reflect the topography features of forest scenic spots, and provide data support and technical basis for scientific management, ecological monitoring, landscape planning, and virtual visualization of forest scenic spots. Taking the Nanling National Forest Park as an example, this paper analyzes the complicated mountain terrain features and the features of unmanned aerial vehicle(UAV), and studies a method for the image acquisition of alpine scenic spots by using the ompound-wing unmanned aerial vehicle (UAV) to establish real-life 3D models, digital surface model (DSM) and digital orthophoto(DOM). With the method of this article, constructed the real 3d scene forest scenic area of 75km2, and analyzed the scene precision and application
results. The experimental results show that the use of the compound-wing UAV for aerial photography of high
mountain scenic spots can not only solve the take-off and landing problem but also improve the timeliness and
reliability of aerial photography. Breakthrough the limitations of traditional two-dimensional results, provide a
three-dimensional model, DSM and DOM, and other results, improve the visual management of scenic spots,
forest investigation and application analysis, and other capabilities. |
