A ship plate recognition method, device and computer-readable storage medium

Abstract

The embodiment of the present invention discloses a ship plate recognition method, device and computer-readable storage medium, wherein the method includes: acquiring a color image of a ship, and converting the color image into a binary image; The pixel points that are continuously white in the color image are merged into at least one first connected region; at least one first corresponding connected region in the color image is determined according to the coordinates of the first connected region; the at least one first connected region is determined according to the target color threshold Screening a corresponding connected region to obtain at least one connected region of the target color; sorting the connected regions of the target color according to the degree of size matching, and selecting the connected region of the target color with the highest degree of size matching as the ship plate of the ship. The ship's ship's plate recognition speed is improved, thus laying the foundation for the rapid recognition of ship's plate characters.

Description

technical field [0001] The invention relates to the field of ship monitoring, in particular to a ship plate recognition method, device and computer-readable storage medium. Background technique [0002] The existing ship nameplate positioning technology is based on mature license plate recognition, using deep learning algorithms and neural network algorithms. [0003] Since the ships in the inland waterway are relatively long, the proportion of the nameplate of the ship in the whole ship is relatively small, so the general image collection and capture use high-resolution images, so that all the information of the entire ship can be included in the picture. In addition , the industry generally adopts 4096*2160 or higher resolution pictures of 7680*4320. [0004] If deep learning and neural network algorithms are used to locate ship nameplates, it will inevitably bring about the problem of recognition speed. In the industry, it takes at least 1 second to identify the 4096*21...
