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 method for detecting suspended matter in drinking mineral water. The invention uses computer vision technology to collect and analyze images of the measured bottled mineral water, and uses an image analysis algorithm to perform target recognition, quantity statistics and monitoring of suspended matter particles in the water. The size range detection has high accuracy. The method of the present invention detects whether there are suspended particles in the bottled mineral water from both qualitative and quantitative aspects. The number of suspended particles is accurate, and the maximum error of the size detection of suspended particles is 0.28mm , the maximum relative error is 6.8%, which has high accuracy.
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...
