Bacteria identification method and device

Abstract

The invention provides a bacteria identification method and a device. The method comprises steps that an image of a to-be-identified bacterium colony is acquired; the bacterium colony characteristic information is extracted from the to-be-identified bacterium colony; according to the extracted bacterium colony characteristic information and a pre-established bacterium colony characteristic database, the bacterial strain information corresponding to the to-be-identified bacterium colony is determined. Through a non-contact mode, the bacterial strain of the bacterium colony is identified, and safety of identification workers is improved; professional bacteria and medical requirements for the identification workers are quite low; an identification process can be rapidly accomplished through an automatic information processing process, an identification result can be further rapidly acquired, identification efficiency is greatly improved, and accuracy of the identification result is quite high; the image of the to-be-identified bacterium colony can be acquired through multiple modes, cost of the bacteria identification device is quite low, and identification cost is greatly reduced.

Description

technical field [0001] The invention relates to the field of image processing technology and bacteria identification technology, in particular to a bacteria identification method and device. Background technique [0002] At present, the commonly used bacterial identification method mainly uses biochemical methods to identify bacteria according to the physiological activity characteristics of the bacteria themselves. Before identification, the bacteria are purified by the culture medium to obtain pure colonies, and then the colonies are punctured into biochemical tubes to observe their color changes. Use this to determine the specific type of colony, or make the colony into a suspension, and identify the suspension according to the special identification card and special analyzer to determine the type of colony. [0003] The above identification of colony types through biochemical methods requires that the colonies can be made into a suspension or that the colonies can be ful...

AI Technical Summary

Problems solved by technology

[0003] The above identification of colony types through biochemical methods requires that the colonies can be made into a suspension or that the colonies can be fully dispersed in the liquid, which requires high purity of the colonies and high requirements for the identification technology of the identification personnel, and during the identification process, when When the identification personnel come into contact with bacteria, there is a certain safety risk, which leads to complex identification of bacteria, high cost and potential safety hazards
