Abstract
In order to realize the function of on-line detection on LCD screen of smart electricity meters in automation test system, and to solve the problem of high wrong judgment rate, a quality on-line detection method based on fast tem-plate matching is proposed in this paper. In the method, a new algorithm of self-learning fast template matching based on Sequential Similarity Detection Algorithm (SSDA) with threshold automatic is adopted. The paper describes in detail how to synthesize characteristics of many templates into a standard template and how to establish real-time and self-learning template library. And SSDA is improved with threshold self-adjusting. The results of experiments indicate that the new method not only has high detection efficiency and matching accuracy, and low wrong judgment rate, but also has great application value of engineering.关键词
