Embodiment 1

[0076] The colony height scanning imaging device provided in this embodiment is as Figure 1 to Figure 3 As shown, it includes a support frame 1 , a data collector 2 installed in the support frame 1 , a colony carrying mechanism 3 , an auxiliary light source assembly 4 and a controller 5 .

[0077] Such as Figure 1 to Figure 3 As shown, the support frame 1 includes a support frame housing 10 in a rectangular parallelepiped structure, two sets of first guide assemblies 11 oppositely installed on the top of the support frame housing and a second guide assembly spanning between the two sets of first guide assemblies 11 Assembly 13, and a support platform 14 installed on the longitudinal beam of the support frame housing 10 for supporting the colony bearing mechanism 3.

[0078] Such as Figure 2 to Figure 3 As shown, the first guide assembly 11 includes a first guide block 111 and a first guide rod 113 passing through the first guide block, and the first guide block 111 and th...

Embodiment 2

[0090] The colony automatic counting device that can distinguish atypical colonies provided in this embodiment includes the colony height scanning imaging device and server provided in Embodiment 1. The controller of the colony height scanning imaging device communicates with the server via a wireless communication module (such as WIFI), and is used to control the operation of the colony height scanning imaging device. The 3D image is sent to the server. The server counts and identifies the colonies according to the two-dimensional images of the colonies and the three-dimensional images of the colonies.

[0091] The specific implementation process of the above-mentioned colony automatic counting equipment that can distinguish atypical colonies provided by this embodiment is as follows:

[0092] (1) Place the auxiliary light source assembly 4 in the rotating platform, and place the petri dish on the auxiliary light source assembly.

[0093] (2) Send start-up information to co...

Embodiment 3

[0096] This embodiment is a further improvement on the basis of Embodiment 1.

[0097] The colony height scanning imaging device provided in this embodiment includes a support frame 1 , a data collector 2 installed in the support frame 1 , a colony carrying mechanism 3 , an auxiliary light source assembly 4 and a controller. The supporting frame 1, the structure of the data collector 2 and the controller installed in the supporting frame 1 have been described in detail in Embodiment 1.

[0098] The colony carrying mechanism adopted in this embodiment includes a rotating platform and a rotating motor 33 . The rotating platform is a cylindrical structure with one end closed, including a cylindrical casing 31 and a bottom plate 32 integrally connected therewith. The rotating shaft provided on one side of the bottom plate 32 passes through the supporting platform 14 and is connected with the output shaft of the second driving motor. Further, such as Figure 4As shown, a fixed b...

Abstract

The invention discloses a bacterial colony height scanning and imaging device which comprises a supporting frame, a data collector, a bacterial colony bearing mechanism, an auxiliary light source assembly and a controller, the data collector is installed in the supporting frame, and the data collector comprises a camera and a miniature laser distance measuring sensor. According to the invention, bacterial colony two-dimensional image acquisition and bacterial colony three-dimensional image acquisition containing height information can be realized at the same time, bacterial colony image information with richer content is provided for bacterial colony counting and identification, and the accuracy of automatic bacterial colony counting equipment is improved. The invention also discloses a bacterial colony automatic counting device and method capable of distinguishing atypical bacterial colonies, and the method comprises the steps: firstly, carrying out the preliminary counting of bacterial colonies based on a bacterial colony two-dimensional image in combination with a plurality of image processing technologies; checking the preliminary colony counting result based on the colony three-dimensional image; and high accuracy of a bacterial colony counting result is ensured from multiple angles. The artificial intelligence classification technology is further applied to the bacterial colony counting process, and atypical bacterial colony distinguishing is achieved.

Description

technical field [0001] The invention belongs to the technical field of colony detection, and relates to the application of artificial intelligence classification technology in colony counting, in particular to a colony height scanning imaging device, an automatic colony counting device capable of distinguishing atypical colonies, and a colony counting and identification method. Background technique [0002] According to the statistics of the World Health Organization (WHO), a total of 2.2 million people die from food-borne and water-borne microbial diseases in the world every year. WHO has set food safety as one of the major issues that are prioritized in this century. Foodborne diseases caused by microorganisms are the primary factor affecting food safety, and foodborne bacteria are the most important type of microorganisms in foodborne microorganisms. It is particularly important to detect the content of foodborne bacteria in food with high accuracy. [0003] The plate co...
