Abstract: To address the poor display of road mark in large-scale real-world 3D scenes,as well as the problem of conflicts or occlusions between road marks and real-world 3D models,the method involves preprocessing road data to generate annotation points in advance,and then publishing a road annotation query service interface. The real-world 3D client queries road annotation information and performs the fusion display process. The fusion visualization of road annotations and real-world 3D models has been achieved,exhibiting features such as computational efficiency,non-occlusion,and compatibility with large-scale real-world 3D applications. This method effectively solves the problem of displaying road networks in real-world 3D scenes,providing important semantic data for real-world 3D,and significantly improving the effectiveness of real-world 3D applications.
