Vision-based Automatic Detection of Suspended Solids in Bottled Mineral Water

Bottled mineral water must be tested to determine whether there exist suspended solids before leaving the factory. At present, it is mainly observed by manual methods. This method is time-consuming and laborious. It relies on artificial subjective feelings, and the detection effect is unsatisfying. Aiming at this problem, an automatic detection method for testing suspended solids in bottled mineral water based on computer vision technology is established in this paper, which includes image acquisition, object recognition of suspended solids, quantity statistics, size estimation, and other image analysis processing. On the basis of this, an automatic detection device for suspended solids in bottled mineral water is designed, and the testing of suspended solids in bottled mineral water is accomplished. The testing results show that the method proposed in this paper can find out suspended solids in bottled mineral water both qualitatively and quantitatively with high precision. The statistics for quantity of suspended solids is accurate. The above device and method could be applied to the detection of bottled mineral water before water leaving the factory with the features of accurate detection, saving labor, improving work efficiency, and easy operation.
