Image target recognition based on video technology
Abstract: With the development of science and technology, image recognition as an important research field of computer vision, by people more and more attention. Among them, the video stream and image recognition combined to achieve a specific goal of real-time monitoring, this technology in agricultural production, medical assistance, traffic supervision and other aspects have been widely used. In this paper, the method of color recognition is used to collect and filter the target pixel values and ranges in the high-speed video stream, and the objects are identified and marked, displayed and output accurately, including location, color, distance measurement and so on, at the same time, through a serial port for data output, and through the research, put forward a wide range of application areas of image recognition technology and the corresponding software tools for modern agriculture and industrial field of robot vision recognition, target positioning and so provide a valuable reference.
