Problems solved by technology

[0004] However, the realization of the automatic identification system also faces many difficulties. The container number has no fixed font and size, and the position of the container number will change with the different boxes. Even in the same box, the box number on different sides The arrangement direction and position will also be different, which will bring certain difficulties to the identification

Embodiment Construction

[0020] The specific implementation manner of the present invention will be described below in conjunction with the accompanying drawings.

[0021] Such as figure 1 A container number identification method described in the embodiment of the present invention includes the following steps:

[0022] Extraction of the container number: Cut out the useful container number from the image containing the container number through image processing technology, and then process the image standardization process on the cut out container number.

[0023] The extraction of the container number includes image preprocessing, image processing, and character cutting and extraction. in

[0024] The image preprocessing includes image reading and standardization, image grayscale and image median filtering.

[0025] The reading and standardization of the image is to convert all photo input formats into 24-bit BMP image format as input samples, and the image size will be scaled to 768*576 (horizont...

Abstract

The invention discloses an identification method of container numbers, which comprises the following steps: extracting the container numbers: cutting an image containing the container numbers by an image processing technology to obtain useful container numbers, and performing the image standardized processing on the cut container number again; and identifying characters: obtaining information after the image standardized processing, and identifying the cut characters by using a neural network technology and an Euclidean distance method. The invention greatly reduces the labor cost, quickens the working efficiency and improves the work accuracy.

Description

technical field [0001] The invention mainly relates to the field of optical character recognition (OCR), in particular to a container number recognition method. Background technique [0002] With the continuous development of computer technology, more and more people expect machines to be able to read characters and numbers automatically, quickly and correctly to improve human work efficiency. One aspect is the automatic recognition technology of car license plates, which is widely used in The transportation department helps departments in need to detect the license plate numbers captured by the video capture system day and night, thereby greatly reducing labor costs, speeding up work efficiency and improving work accuracy. Another aspect is the container number identification system of the container. [0003] Each container has its unique box number, which will be used every time the container enters and exits the port, warehouse, and customs. The box number will appear on...
