Abstract

In order to solve bottleneck problems such as slow and difficulty of real-time presentation and browsing of large-scale realistic models, aiming at the landform and ecological characteristics of wetland parks, this paper used examples as the research object to study the efficient three-dimensional modeling and lightweight presentation technology of UAV aerial survey data of wetland parks. Based on the linear combination equation of quadratic Gaussian radial basis function, this paper proposed a quadtree segmentation three-dimensional modeling algorithm for aerial survey spatial position data, and realized the smooth connection and optimization of the model. Experiments show that the method changes the traditional cumbersome modeling method and process of 3D modeling of aerial survey data. It used a small amount of modeling data to efficiently and quickly build and present large-scale 3D models, and greatly reduce the amount of data for building models with satisfied visual effects. The method is not only suitable for efficient large-scale 3D modeling and presentation of wetland parks, but also has reference value for large-scale three-dimensional modeling and presentation of ecological protection areas such as natural scenic spots and forest areas.
