| Summary: | 碩士 === 聖約翰科技大學 === 電機工程系碩士班 === 97 === In this thesis, we have designed and integrated an automatic optical inspection system, emphasizing on software implementation of the image processing, measurement and analysis utilities. As for the hardware equipments, except the LED illumination unit and the custom-tailored machinery are self-designed, others like the CCD camera, the lens and frame-grabber are bought ready-made ones.
By comparing the support functions of several main import brands of the optical inspection machine, we propose an optical inspecting procedure. By using the Windows-based user interface, we implement nine inspecting software tools, namely, the average gray level tool, the thresholding tool, the positioning tool, the edge detection tool, the binary large object (BLOB) tool, the template building tool, the smart matching tool, the inspection sequence tool, and the platform operation tool. All these tools can be used in an inspection with single operation and can also be arranged in a proper sequence of operations to fulfill a complicated inspection procedure.
We use several part sample images of mobile phone keypads with defects provided by the supplier to verify our fulfilled system and all obtain accurate results.
