Embodiment 1
[0053] Embodiment 1: This method for detecting suspended matter in drinking mineral water, the specific steps are as follows:
[0054] (1) Send the bottled mineral water to be detected into the automatic detection device. The bottled mineral water rolls along the slope to the bottom and stops at the motor control door. The rolling action makes the suspended particles in the bottle in a state of motion. Due to the diffuse reflection of light on the surface of the suspended particles, the suspended particles are clear and bright as a whole, and have a good imaging effect in the image collected by the visual sensor. The LED light source of the automatic detection device is located at the lower left end of the rear wall of the detection box, perpendicular to the mineral water bottle Bottom irradiation can illuminate the state of the whole bottle of water, avoiding the problem that side irradiation is easily affected by the convex and concave lines of the side wall of the mineral wa...

Abstract
The invention discloses a drinking spring water suspended matter detection method. According to the drinking spring water suspended matter detection method disclosed by the invention, image collectionand analysis are performed on a detected bottled spring water by using the computer vision technology, and target identification, number counting and size range detection are performed on suspended matter particles in the water by using an image analysis algorithm, so that the accuracy is relatively high. According to the method disclosed by the invention, whether the suspended matter particles exist in the bottled spring water is qualitatively and quantitatively detected, the number counting of the suspended matter particles is accurate, the maximum error of the size detection of the suspended matter particles is 0.28mm, the maximum relative error is 6.8%, and the accuracy is relatively high.
Description
technical field [0001] The invention belongs to the field of computer vision and image processing research, in particular to a method for detecting suspended matter in drinking mineral water. Background technique [0002] Water quality testing is a very important key link in the product quality management of each water plant, and it is related to the drinking water health of each of us. At present, there are still some problems in the testing of drinking water quality in my country, such as uneven distribution of drinking water quality testing centers, unreasonable setting of sampling points for drinking water quality testing, and lack of advanced testing instruments. [0003] At present, the production process of bottled mineral water is basically: source water→coarse filtration→fine filtration→deionization purification (ion exchange, reverse osmosis, distillation)→sterilization→filling and capping→light inspection→finished product. For the light inspection link, due to th...
