In the city three-dimensional scene visualization engine, it will generate a huge amount of data to cause real-time transmission difficult by using the traditional triangular mesh mode. A simplified method for building models is presented. This method can simplify three-dimensional model by adaptive clustering and can preserve building model contour information well at the same time. The experimental...
According to human visual sensitivity, in this paper, we present a new simplification of point cloud based on point saliency. In order to find the nearest K points, we need to divide the space of Point cloud firstly. Secondly, we compute the normal vector and saliency of every point. At last, we combine octree structure and saliency to simplify point cloud data. Experiments show that our method can...
