英文摘要：

IC with multi-lead and small-pitch is difficult to detect and locate in electronic product manufacturing process. Aiming at the image recognition and locating problems of IC in production of high-speed and high-precision surface mounting machine, tasks of IC vision detection are introduced. A kind of recognition and locating algorithm and the technique of realization, which is self-researched, are also brought forward. The result of actual running demonstrates that the speed and accuracy of the algorithm are good enough to meet the practical application, and the algorithm also has strong robustness.
