Description

technical field [0001] The invention relates to an underwater measuring device, in particular to an underwater vibrating table video measuring system based on binocular vision. Background technique [0002] In the safety and reliability research of large-scale engineering structures, the dynamic test of large-scale engineering structures under the excitation of wave and water flow coupling earthquakes is carried out through the shaking table of underwater simulated earthquakes, so as to study large-scale civil, water conservancy and marine engineering and its infrastructure The earthquake disaster process and structure are affected by complex dynamic effects such as earthquakes, waves, and ocean currents. In the dynamic test process, the most commonly used measurement method is to stick strain gauges on the test piece to obtain the displacement and strain of the test piece. However, cleaning, grinding, and pasting of strain gauges are required during measurement, and the st...

AI Technical Summary

Problems solved by technology

However, cleaning, grinding, and pasting of strain gauges are required during measurement, and strain gauges cannot be reused, and strain gauges need to be re-pasted for each measurement

In addition, in underwater applications, the strain gauges need to be protected, which is time-consuming and labor-intensive
