Visual measurement system for underwater concrete block installation

Abstract

The invention discloses a visual measuring system for underwater concrete block installation to acquire images and feature parameters of concrete blocks above a datum line under the water. The system comprises at least one triangulateration assembly which includes a triangulateration rack, a right triangle triangulateration scaleplate, a first underwater camera and a first underwater floodlight, at least one datum line measuring assembly which includes a datum line measuring rack, a long-strip-shaped datum line measuring scaleplate, a second underwater camera and a second underwater floodlight, and an underwater image acquiring and measuring host, wherein the underwater image acquiring and measuring host receives acquired images through a watertight cable and working out the horizontal distance between the installation concrete blocks and the datum line and seam widths and stagger values between the installation concrete blocks and installed concrete blocks so that positioning of the installation concrete blocks can be guided. The visual measuring system can visually display the relative positions of the concrete blocks in water through the images in real time and help water surface conductors quickly and safely position the concrete blocks, and meanwhile, by measuring the underwater image features, concrete block positioning is precisely guided.

Description

Problems solved by technology

[0003] The accuracy and efficiency of underwater concrete block installation affect the construction quality and progress of the entire square wharf. The traditional construction method mainly relies on divers to measure underwater with a ruler, and communicate with the surface command personnel through underwater walkie-talkies to direct the construction of concrete blocks. Installation, due to the complex underwater working environment, the construction efficiency is relatively low, which also has a certain impact on the safety of divers. At the same time, due to human uncertainties, the measurement accuracy cannot be guaranteed, and the construction quality cannot be effectively supervised.
