Embodiment Construction
[0026] In order to make the purpose, technical solution and advantages of the present application clearer, the present application will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present application, and are not intended to limit the present application.
[0027] The glue overflow defect detection method provided by this application can be applied to such as figure 1 shown in the application environment. The glue overflow defect detection method is applied to a glue overflow defect detection system. The glue overflow defect detection system includes an image acquisition device 102 and a terminal 104 . Wherein, the image acquisition device 102 communicates with the terminal 104 through a network. The original image of the workpiece to be measured is collected by the image acquisition device, and the original image of the w...

The invention relates to the field of flaw detection, and provides a glue overflow flaw detection method and device, computer equipment and a readable storage medium. The method comprises the following steps: acquiring an image of each to-be-detected hole site from an original image of a to-be-detected workpiece; calculating the image brightness of each to-be-measured hole site according to the image of each to-be-measured hole site; based on the image brightness of each to-be-detected hole site, a preset brightness threshold and a processing strategy, identifying the image of the corresponding to-be-detected hole site to obtain a non-defective area of each to-be-detected hole site; according to the non-defective region of each to-be-detected hole site, determining the defective region area of the corresponding to-be-detected hole site; and when the area of the flaw region of at least one to-be-detected hole site is greater than or equal to a first preset area, determining that the to-be-detected workpiece is a defective product. By adopting the method, the detection accuracy and the detection efficiency can be improved.
Description
technical field [0001] The present application relates to the technical field of defect detection, in particular to a method, device, computer equipment and readable storage medium for detecting a glue overflow defect. Background technique [0002] In the production process of the mobile phone case, the handset part is usually installed on the case by dispensing glue. During the dispensing process, glue will overflow, which will block the earpiece and affect the function of the mobile phone. Traditional glue overflow inspection usually relies on manual inspection. During the inspection, the sample to be inspected is placed on a fixed mold, and the area to be inspected of the sample to be inspected is enlarged and displayed on the screen through a lens, and whether there is a defect is judged by manual visual inspection. However, the evaluation criteria of manual inspection vary from person to person, and there are different judgments on workpiece defects, and workers who en...
