Urban underground space three-dimensional information visualization system and method

The invention provides an urban underground space three-dimensional information visualization system and method, and relates to the technical field of urban underground space management and three-dimensional geographic information systems. According to the invention, through arranging the sensor monitoring system in various facilities of the underground space, the acquired data is integrated intoan underground building, underground traffic and pipeline three-dimensional model for visual display. The urban underground space three-dimensional information visualization system is constructed. Theoverall operation condition of the underground space can be fed back to managers in real time through the system, the managers can conveniently conduct corresponding work arrangement on staff, the event type and the event level causing the abnormal state of the underground space are intelligently judged, and a solution is generated; early warning judgment is carried out according to whether the event range is enlarged or
