Auto-focusing motor control and image processing of the somatic cell test system

Somatic cell have a key effect on the quality of milk. A test instrument has been developed, it can rapidly and accurately test the quantity of somatic cell for milk. Based on the analysis of milk adhesion behavior, the test system can complete a series of complicated work, such as auto-focusing and image processing. Auto-focusing is an integrated of the grayness and Laplacian operator integration. Image processing includes automatically feeding films, classification, edge identification, image collecting and processing. The results of experiments have showed that the test system can satisfy the need of milk somatic cell test, and it has characteristics of automation and high testing precision.
