Methods and systems for monitoring and early warning of safety statuses of bridges

A system for monitoring and early warning of a safety status of a bridge, comprising:

• an acquisition module, configured to perform three-dimensional (3D) scanning on a bridge to be monitored, and construct a 3D model corresponding to the bridge to be monitored based on a 3D scanning result of the 3D scanning;
• a determination module, configured to determine, based on the 3D model, whether the bridge to be monitored is a new bridge or an old bridge;
• a first warning module, configured to, in response to determining that the bridge to be monitored is the new bridge,
• collect first monitoring data of the bridge to be monitored in real time,
• determine a first monitoring data threshold set by analyzing the 3D model,
• perform a comparison between the first monitoring data and the first monitoring data threshold set to obtain a first comparison result corresponding to the comparison, and display the first comparison result in real time;
• a second warning module, configured to, in response to determining that the bridge to be monitored is the old bridge,
• collect second monitoring data of the bridge to be monitored in real time,
• determine a second monitoring data threshold set by analyzing the 3D model,
• perform a comparison between the second monitoring data and the second threshold to obtain a second comparison result corresponding to the comparison, and display the second comparison result in real time.
