An underground information visualization method and its deep shaft application

Abstract

With the development and utilization of underground space, the emergence of visualization technology and the increasing amount of associated information, underground engineering information visualization has become increasingly relevant and important. However, at present, information visualization problems are commonly encountered during the process of visualization expression of underground engineering information. These problems include monotonous visualization form, color matching ignoring visual perception, and spatial occlusion reducing information readability. These issues not only reduce the visualization effect and the efficiency of information acquisition, but they are also associated with certain safety issues. In view of the problems that exist in underground engineering information visualization, the aim of this paper was to provide a theoretical basis applicable to cases in order to improve the visualization expression of underground spatial information. This paper conducted research from two perspectives: the visualization principle and the visualization method. The No. 1 shaft deep foundation pit of the Shanghai hard X-ray project was used as the engineering background in order to realize the visual display, analysis, and early warning of the engineering data of the foundation pit project.
