The invention relates to the technical field of monitoring, in particular to a tunnel structure health monitoring system based on a three-dimensional laser scanning technology, which comprises a measurement data acquisition and preprocessing module, a data analysis module and an intelligent prediction module, the measurement data acquisition and preprocessing module performs three-dimensional laser scanning on a target object to generate point cloud data and preprocesses the point cloud data; the data analysis module comprises a three-dimensional model reconstruction module and a finite element model establishment and correction module and is used for performing 3D model reconstruction on a three-dimensional laser scanning result; and the intelligent prediction module performs safety assessment on the deformation condition of the model in each time period in the future. According to the tunnel structure health monitoring system based on the three-dimensional laser scanning technology, the full-automatic high-intelligence three-dimensional laser scanning equipment which is integrally designed and integrates data acquisition, software analysis and prediction and evaluation and the color touch display screen are adopted, operation is easier, and prediction and evaluation of multiple time periods and a reasonable scheme are obtained in real time.
Description
technical field [0001] The invention relates to the technical field of monitoring, in particular to a tunnel structure health monitoring system based on three-dimensional laser scanning technology. Background technique [0002] At present, due to the differences in geological conditions, underground facilities, subway transportation conditions and requirements, and regulatory requirements between domestic and foreign countries, the application of 3D laser scanning technology in China requires a large number of independent research and development, suitable for China's national conditions and application needs. Software and supporting hardware can bring out the technological level and function that the technology should have. The traditional detection methods mainly include total station, GPSRTK technology, etc. When the total station locates the coordinates, it is affected by many factors such as weather and traffic, and has many restrictions. In addition, its measurement di...
