Description

technical field

[0001] The invention relates to an image processing method and equipment thereof. Background technique

[0002] At present, there are many technologies that capture the captured image by capturing the appearance of the object such as the bottle mouth, and check whether there are any defects such as foreign matter mixed in, breakage, gaps, and dirt based on the captured image, but these only use the captured image data Perform binarization with a certain threshold, and test the black or white area (area ratio) of the binarized data to check for defects. This simple binarization method is sometimes difficult to improve the reliability of the inspection; Some image processing equipment can determine whether a specific part with obvious local shape features such as the mouth of a glass bottle is qualified, and can quickly and accurately inspect it, but objects other than glass bottles cannot be inspected because they do not have such obvious local features; some ...
