3D data visualization system of immersive underground laboratory

The construction of underground laboratories is a key step in the deep geological disposal of high-level radioactive waste. Due to the complex construction structure of underground laboratory engineering and the difficulty of project implementation, how to effectively plan, design and evaluate underground laboratory construction projects is an important issue in the construction of underground laboratories. Based on geometric structure, topological relationship and geological semantics, this paper integrates multi-source data from underground laboratories and constructs a 3D digital model of underground laboratory. The 3D data visualization system of underground laboratory of immersed high-level waste geological disposal was constructed by using terrain automatic generation algorithm, perspective and section in 3D model visualization, and immersive interactive means of viewpoint positioning. The experimental results show that the system can provide an intuitive interactive means for the comprehensive analysis of underground laboratory data, and provide reference for the demonstration of underground laboratory engineering construction planning and design.
