Problems solved by technology

[0005] The main purpose of the present invention is to propose a method, system and device for detecting refrigerator casters based on visual recognition, aiming at the collinear production of multiple types of refrigerators in the existing commercial refrigerator flexible production line. Different types of refrigerators have different installation forms and are prone to casters. For the problems of missed installation, wrong installation, and missing installation of caster bolts, machine inspection is used instead of manual inspection to quickly obtain the abnormal position and abnormal cause of the caster wheel of the refrigerator, which improves the detection efficiency and accuracy

Embodiment 1

[0057] Such as figure 1 As shown, a method for detecting casters of refrigerators based on visual recognition, the operation process is as follows:

[0058] Step 1, collect the pictures of the produced freezer bottom plate, set up the freezer caster data set and the caster bolt data set, and establish the freezer bottom plate database;

[0059] Step 2, use the algorithm to expand and enhance the number of freezer floor pictures in the database, and use manual labeling;

[0060] Step 3, split the marked data into training set and verification set, perform training and verification, generate multiple types of floor inspection models, and store the floor inspection models in the inspection system;

[0061] Step 4, control the industrial camera to take pictures of the bottom plate of the freezer to be tested, and obtain the picture of the bottom plate;

[0062] Step 5, preprocessing the picture of the bottom plate of the freezer obtained in step 4, obtaining the minimum circumsc...

Embodiment 2

[0073] A visual recognition-based detection system for refrigerator casters, including:

[0074] Acquisition module, storage module, expansion module, test module, camera module, preprocessing module, judgment module and display module;

[0075] Wherein the collection module is used to collect the pictures of the produced freezer bottom plate, and send the collected data to the storage module;

[0076] The storage module receives the bottom plate data sent by the acquisition module, organizes the data, and establishes a refrigerator bottom plate database;

[0077] The expansion module calls the bottom plate data in the database, uses an algorithm to expand the number of bottom plate pictures, and uses manual marking, and sends the marked data to the verification module;

[0078] The test module receives the marked expansion data sent by the expansion module, splits it into a training set and a verification set, performs training and verification again, generates a base plate ...

Embodiment 3

[0090] A device for detecting caster wheels of a refrigerator based on visual recognition, comprising: a processor and a memory, the processor is coupled to the memory, a program for detecting caster wheels of a refrigerator based on visual recognition is stored in the memory, and the processor executes the The freezer caster detection program based on visual recognition is to realize any one based on visual recognition caster detection method of freezer as claimed in claims 1-8;

[0091] In the specific implementation process, the pictures of the bottom plates of various types of refrigerators produced by the company are collected, the database of the bottom plates of the refrigerators is established, and the number of pictures of the bottom plates of the refrigerators in the database is expanded and marked by the algorithm, and they are divided into training sets and verification sets for training and verification. Generate different types of floor inspection models, start th...

Abstract

The invention discloses a refrigerator trundle detection method, system and device based on visual identification, and belongs to the technical field of commercial electric appliance manufacturing, and the method comprises the steps: collecting produced refrigerator bottom plate pictures, building a refrigerator bottom plate database, carrying out the expansion and marking of the number of the refrigerator bottom plate pictures in the database through an algorithm, splitting the pictures into a training set and a verification set, carrying out training and verification to generate different types of bottom plate detection models; starting a refrigerator detection conveyor belt; controlling an industrial camera to photograph a refrigerator; obtaining a minimum external rectangle size; intercepting and generating a to-be-detected refrigerator bottom plate picture according to the size; calling a bottom plate detection model from a detection system according to the size, and carrying out judgment; and directing workers to carry out error correction installation according to a judgment result. According to the invention, the detection efficiency and the accuracy are improved, the detected installation defects are prompted through alarming, the installation workers are guided to quickly position the types and the positions of the defects, and therefore the defects are eliminated, correct installation of the trundles is guaranteed, and the production qualification rate is improved.

Description

technical field [0001] The invention belongs to the technical field of commercial electrical appliances manufacturing, and in particular relates to a method, system and device for detecting casters of refrigerators based on visual recognition. Background technique [0002] At present, with the improvement of living standards, modern people have higher and higher requirements for food quality. The cold chain industry has developed rapidly, and commercial refrigerators have emerged as the times require. However, commercial refrigerators are bulky and inconvenient to carry during use. Therefore, it is necessary to install casters at the bottom of the freezer to assist in the movement during production; [0003] In the production process of commercial refrigerators, the installation and inspection of casters of refrigerators in the prior art usually uses manual inspection to detect the installation results of casters. Lack of installation, etc. Since the current commercial refr...
