Application Cases

Overpass safety monitoring
Overpass Safety Monitoring

Overpasses play a vital role in regional traffic, so their structural safety attracts wide attention. To ensure the stability of the bridge, an online vision tracker was used for safety monitoring, tracking pier settlement in real time with a monitoring frequency down to one second. The system delivers continuous automated data that supports timely maintenance decisions.
