Abstract
Recent advances in 3D spatial data capture, such as high resolution satellite images and laser scanning as well as corresponding data processing and modeling technologies, have led to the generation of large amounts of datasets on terrains, buildings, roads and other features. The rapid transmission and visualization of 3D models has become a ‘bottleneck’ of internet-based applications. This paper proposes a robust algorithm to generate multi-resolution models for rapid visualization and network transmission of 3D models. Experiments were undertaken to evaluate the performance of the proposed algorithm. Experimental results demonstrate that the proposed algorithm achieves good performance in terms of running speed, accuracy, encoding of multi-resolution models, and network transmission.
