Abstract: With the popularity of automobiles and the improvement of computer vision recognition technology, smart tag discovery has evolved into an important part of smart traffic management. The license plate location is used to segment the vehicle image and collect the tag region for the follow-up recognition system to screen. It is commonly used by executives in canny rush hour jams, car video monitoring, and other sectors. Two tag discovery strategies are considered in this paper: one uses Sobel edge identification and the other uses morphological angle detection. Two tag location strategies are implemented using OpenCV and Visual Studio 2012 under the Windows framework, and the two calculations are thoroughly investigated from the standpoint of tag identification accuracy. These techniques have high efficacy and intuitiveness, which serve as a reminder for later tag recognition. Intelligent Transportation System, License Plate Detection, Edge Detection, and Morphological Gradient Detection are some of the catchphrases.
