Bar code defect detection method and device, equipment, storage medium and program product

The embodiment of the invention provides a bar code defect detection method and device, equipment, a storage medium and a program product, and the method comprises the steps: determining a first bar code region in a first image under the condition that the first image is obtained; performing denoising processing on the first bar code area to obtain the first bar code area after denoising processing; according to the denoised first bar code area, extracting the outer contour of the bar code in the first image to obtain a second bar code area; correcting the second bar code area through a preset width and a preset height to obtain a second image corresponding to the bar code in the first image; and performing bar code defect detection based on the second image. Therefore, a large amount of data does not need to be collected to train the model to position the bar code area, and the bar code area can be positioned more simply and accurately, so that bar code defect detection can be performed on the bar code area.
