[0091] Example 1:
[0092] like Figure 1-6 , a method for visual inspection of bottle packaging quality, comprising the following steps:
[0093] Step 1: Obtain bottle image and pre-processing;
[0094] Step 2: Position the support ring in the image;
[0095] Step 3: Calibrate the cover, liquid level and coding detection area;
[0096] Step 4: Check for defects in caps, fluid levels, and coding.
[0097] In step 1, through the backlight and RGB three-color strip light illumination, use the CCD industrial camera and the image acquisition card to collect the bottle image, and then send the collected image to the industrial computer for preprocessing, and use the median filtering method to remove the image acquisition and Noise points that exist during transmission.
[0098] Step 2 includes a coarse positioning step and a fine positioning step;
[0099] (1) Coarse positioning steps:
[0100] For the preprocessed image, select the positioning region Reg loca , the positio...
