Embodiment Construction

[0038] The present invention will be specifically introduced below in conjunction with the accompanying drawings and specific embodiments.

[0039] Such as figure 1As shown, a kind of automatic recognition method of water gauge reading based on multi-model fusion provided by the present invention comprises the following steps:

[0040] (1) Perform water gauge area detection on the collected original image;

[0041] (2) Extract the local image of the water gauge from the original image;

[0042] (3) Perform image processing on the local image of the water gauge to obtain its changing rotation and translation matrix M;

[0043] (4) The original image is corrected by the rotation-translation matrix M obtained in step (3), and the corrected original image is obtained;

[0044] (5) According to the corrected original image rotation center position information and the length and width values, the corrected partial image of the water gauge is extracted, and the scale character det...

Abstract

The invention discloses a ship water gauge reading automatic identification method based on multi-model fusion. The method comprises the following steps: (1) carrying out water gauge area detection onan original image; (2) cutting out a local image of the water gauge from the original image; (3) carrying out image processing on the local image of the water gauge; (4) correcting the original imageto obtain a corrected original image; (5) digging out the corrected local image of the water gauge, and performing scale character detection to obtain a scale character detection result; (6) correcting a scale character detection result to obtain a water gauge scale reading; (7) establishing a scale reading model; (8) performing image segmentation on the corrected original image to obtain waterline position information; (9) inputting the waterline position information into a scale reading model to calculate the scale reading of the waterline of the water gauge; according to the invention, theproblem of automatic reading of the current ship water gauge can be effectively solved, and the working efficiency is greatly improved; and the method can be reused in other application scenes related to water gauge reading.

Description

technical field [0001] The invention relates to an automatic recognition method for ship water gauge readings based on multi-model fusion, and belongs to the field of ship water gauge scale detection. Background technique [0002] With the development of the shipping industry, the reading of the draft value of the ship's six-sided water gauge has become the most critical factor for the accuracy of the water gauge weight measurement. The original manual visual reading method has problems such as large errors and too subjective; in addition, the observation environment The inconvenience increases the cost and workload of manual visual inspection, and also increases the risk of personnel safety; in addition to the traditional manual visual inspection method, there are currently many solutions to try to solve this problem; methods based on physical sensors include: by installing dual pressure sensor to detect the draft of the ship's side; or transmit ultrasonic waves through ult...
