Part size measurement method based on charge coupled device (CCD)

Abstract

The invention provides a part size measurement method based on a charge coupled device (CCD). According to the part size measurement method, feature point recognition technology is adopted, pixels are classified through feature points of a part, the size of the whole part is measured, prior knowledge of the part is not required, and measurement for the common part is achieved. According to the method, high-speed measurement is conducted, and meanwhile a precision requirement is met. The part size measurement method based on the CCD is simple in algorithm, low in cost and good in application prospect due to the facts that only the CCD and a computer are required for hardware implementation and a complex mechanical structure is not required.
