Abstract

The invention belongs to the technical field of ship measurement, particularly relates to a ship water gauge identification method, a ship water gauge identification system and a ship water gauge identification device based on a wall-climbing robot. The invention aims to solve the problems that an existing water gauge identification method is not easy to perform water gauge reading in a short distance and data reading is inaccurate. The method comprises the steps that carrying out scale calibration and reference identification coordinate alignment on the t frame, the t-1 frame and thet+1 frame of collected continuous k frames of water level images to obtain a fused image; performing curve fitting on the waterline discrete points of the fused image; obtaining the image parameters of the fused image, and calculating water surface scale values in combination with a fitting waterline; obtaining water surface water gauge scale readings based on k-2 water surface scale values. According to the invention, the wall-climbing robot is adopted to acquire video data at a short distance and read the scales of the image water gauge, so that the danger is reduced. The labor cost is saved. The efficiency and accuracy are improved. The systematic management is realized, and storage, management and search are easy in operation.

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...
