Traditional Chinese medicine bag number identification algorithm

Abstract

The invention discloses a traditional Chinese medicine bag number identification algorithm, and the algorithm comprises the steps: firstly carrying out the preprocessing, which comprises graying and filtering denoising, of a collected image; carrying out threshold segmentation binaryzation by utilizing an improved Otsu method; and finally, performing connected domain marking, identifying the number of connected domains in the image, and completing the identification of the number of traditional Chinese medicine bags. According to the algorithm, the problem that image details are easy to lose under the condition of non-uniform image illumination of a traditional Otsu method is solved, the algorithm can well identify the number of traditional Chinese medicines, and the intelligent medicine taking speed and accuracy of a traditional Chinese medicine pharmacy are greatly improved.

Description

technical field [0001] The invention relates to the technical field of intelligent traditional Chinese medicine pharmacies, in particular to an algorithm for identifying the number of traditional Chinese medicine bags. Background technique [0002] The development of science and technology has driven the automation of production. Automated production can better adapt to large-scale production, save the cost of enterprises, and improve production efficiency. With the continuous development of society, automation equipment has been used in all aspects of our lives. The application of automation technology can liberate manpower and greatly increase productivity. [0003] Nowadays, with the rapid development of image data acquisition equipment technology and the Internet, machine vision has become a hot topic. The advantage of machine vision is that it has no time limit, and it gets rid of the shortcoming that human eyes are prone to fatigue and cannot work for a long time. A...

Problems solved by technology

[0004] At present, there are two main types of identification of the number of mainstream medicine bags in traditional Chinese medicine pharmacies: one is manual distribution of traditional Chinese medicine, and manpower is used to count the number of medicine bags. Loss due to problematic deviation

The other is mechanical identification controlled by PLC, which uses programs to control the identification process of PLC. However, this identification method has great shortcomings. It is necessary to place the traditional Chinese medicine bag in a specific position, which is very inconvenient to use, and the price of PLC is relatively expensive.
