The convenient use of water conservancy, transportation, environment, medical treatment, power grid and other aspects of cities in any country affects people\u2019s healthy life. Therefore, it is urgent to build a smart city. For smart city, intelligent identification and management is a very large and complex problem. As one of the high and new technologies, the intelligent recognition of machine vision derived from artificial intelligence has always been a hot spot of great concern. It just provides convenience for the development of smart city and becomes the development direction of smart city construction in the future. Based on this, the role of machine vision is to connect with the computer through wireless sensors such as cameras to simulate an eye that can represent human visual function. This simulated eye can be recognized intelligently in real time. It transmits the recognized information to the computer, and the computer will analyze and process the obtained information for judgment and recognition. This paper will mainly use the optimal threshold segmentation algorithm based on Machine Vision video processing to solve the problem of urban intelligent recognition, and use a specific algorithm to solve some difficulties and obstacles in intelligent recognition. The traditional optimal threshold segmentation algorithm, the optimal threshold segmentation algorithm and the improved optimal threshold segmentation algorithm are experimentally compared. After experimental comparison, it is found that the optimal threshold segmentation algorithm, the improved optimal threshold segmentation algorithm and the traditional optimal threshold segmentation algorithm can intelligently identify the types of buildings and urban traffic signs in the city, Compared with the improved optimal threshold segmentation algorithm, the improved optimal threshold segmentation algorithm improves the response speed, real-time performance, stability and accuracy of the algorithm. Therefore, the optimal threshold segmentation algorithm after the well meets the needs of building the system, and can be useful in the process of intelligent recognition. This improvement is also necessary, which is conducive to the subsequent system construction.<\/jats:p>","DOI":"10.1155\/2022\/6605532","type":"journal-article","created":{"date-parts":[[2022,6,9]],"date-time":"2022-06-09T16:50:22Z","timestamp":1654793422000},"page":"1-13","source":"Crossref","is-referenced-by-count":2,"title":["Research on Intelligent Recognition and Management of Smart City Based on Machine Vision"],"prefix":"10.1155","volume":"2022","author":[{"ORCID":"https:\/\/orcid.org\/0000-0001-7957-1620","authenticated-orcid":true,"given":"Rulin","family":"Liu","sequence":"first","affiliation":[{"name":"College of Electronic and Information Engineering, Chongqing Technology and Business Institute, 402160 Chong Qing, China"}]},{"given":"Longfeng","family":"Liu","sequence":"additional","affiliation":[{"name":"College of Accounting and Finance, Chongqing Technology and Business Institute, 402160 Chong Qing, China"}]}],"member":"311","reference":[{"key":"1","doi-asserted-by":"publisher","DOI":"10.2307\/2095062"},{"volume-title":"Environmental Problems in an Urbanizing World","year":"2001","author":"J.
