Ship water gauge recognition method, system and device based on wall-climbing robot

Abstract

The invention belongs to the technical field of ship measurement, and in particular relates to a method, system and device for ship water gauge recognition based on a wall-climbing robot, aiming to solve the problem that the existing water gauge recognition method is not easy to read the water gauge at close range and the data reading is inaccurate The problem. The method of the present invention comprises: performing scale positioning and coordinate alignment of reference marks on the tth frame, t-1 frame, and t+1 image of the collected continuous k-frame water level images to obtain a fusion image; performing a curve on the waterline discrete points of the fusion image Fitting; obtain the fused image parameters and combine the fitting waterline to calculate the scale value of the water surface; use the scale prediction network to obtain the scale reading of the water surface water scale based on k-2 water surface scale values. The invention uses a wall-climbing robot to obtain video data at close range, reads the scale of the image water scale, reduces risks, saves labor costs, improves efficiency and accuracy, and realizes systematic management, which is easy to store, manage and search.

Description

technical field [0001] The invention belongs to the technical field of ship measurement, and in particular relates to a ship water gauge recognition method, system and device based on a wall-climbing robot. Background technique [0002] The ship's draft gauge is a common measurement method for bulk dry bulk cargo transported by water. With the continuous development of my country's foreign trade, the import volume of bulk cargo by sea is increasing rapidly year by year, and the accuracy requirements for water gauge weight are also getting higher and higher. The traditional water gauge is based on reading the draft line of the ship to be measured, and calculates the weight of the cargo carried by the accurate chart of the ship through the measurement of the displacement and ship materials of the carrying ship. [0003] The traditional water gauge identification method is relatively easy for ships to observe on the side of the shore, but it is difficult to observe the side of...
