Underwater laser datum line measuring system based on computer vision

Abstract

The invention relates to the technical field of ocean development and underwater measurement, and discloses an underwater laser datum line measuring system based on computer vision, which comprises a main body bracket, and the top of the main body bracket is fixedly connected with a handle. According to the underwater laser datum line measuring system based on computer vision, the inflatable bag is conveniently bound on the mounting frame through the mounting belt and fixed, inflation of the air tank to the inflatable bag is conveniently controlled through the inflation valve according to requirements, the buoyancy of the inflatable bag is accordingly adjusted, meanwhile, the inflatable bag is conveniently deflated through the deflation valve, the buoyancy of the inflatable bag is reduced, the effects of quick floating and buoyancy balance adjustment are achieved, more labor is saved for workers, a rotating lead screw rotates in a power box through a rotating motor and a rotating bearing, and a lifting shaft ascends and descends outside the power box through rotation of the rotating lead screw; therefore, the lifting block, the supporting rod and the grip are driven by the extension block to lift, and the height of the grip is adjusted according to the use habits and actual conditions of a user.

Description

technical field [0001] The invention relates to the technical field of marine development and underwater measurement, in particular to an underwater laser reference line measurement system based on computer vision. Background technique [0002] The ocean is the cradle of life, the treasure house of resources, the lifeline of transportation and a strategic location. The construction of global ocean facilities is developing towards large-scale and high-precision. At the same time, the requirements for the accuracy and speed of underwater construction are also increasing. As the auxiliary measures of underwater construction, timely and accurate underwater measurement is the key to ensure the quality of construction. [0003] At present, in the computer vision underwater laser reference line measurement system, it is necessary to use portable laser reference line tooling to install and measure underwater gravity square docks. However, the existing laser reference line tooling ha...
