STUDY ON THE STATE RECOGNITION OF THE IC COMPONENTS IN PACKING

摘要

In the IC components' packing, the accuracy of the components' position and right face are required. In order to assure the IC component' proper state, the fast recognition of the IC components is an important technique. Through analyzing all kinds of IC components, a recognition algorithm based on their feature was proposed. Transforming the image recognition into finding the feature in the sampling image greatly simplifies the online recognition of the IC Components. Some useful parts can be extracted from the image by image preprocessing and partition. Then the locating point based on the feature of the IC component could be found. Finally whether the component is in proper state could be told. In this paper, the design of the recognition algorithm was studied, and the recognition program flow chart was presented.
