Monocular 3D Video Extensometer
Bridge health monitoring systems demand long-term operation, data continuity and remote management. The Huangpu District bridge health monitoring project improves data completeness and O&M efficiency through power monitoring, automatic restart after power failure, cloud platform data viewing and warning feedback.
Bridges produce vertical displacement, dynamic deflection and vibration response under dynamic loads such as vehicles and trains. Based on the Wuhan metro viaduct dynamic deflection monitoring project, this article introduces the value of Haytham vision trackers in long-term online bridge monitoring.
Haytham DIC allows observing not only changes at a single measurement point but also the evolution of strain distribution over the entire structure surface synchronously.
In static loading tests of special-shaped columns, DIC 3D full-field strain measurement provides more comprehensive structural response analysis.
Haytham DIC uses non-contact measurement, acquiring vibration response data directly without touching the equipment under test.
Haytham DIC provides continuous, comprehensive deformation data throughout loading, capturing every detail for more complete structural response information.
Haytham DIC continuously acquires the entire test process — not only recording results at key stages, but preserving the whole timeline of damage initiation, propagation and evolution.
For the testing characteristics of tiny specimens, the optical vision measurement / video extensometer approach obtains tensile deformation data without touching the specimen — ideal for tensile testing of fibers, fine metal wires and single-fiber composites.
Haytham Technology's featureless vision measurement solution for compression deformation provides a stable non-contact means for composite materials.
