Embodiment Construction

[0009] The present invention is a recognition method of an electronic field of view image based on city signal visual perception. The steps are as follows: first, a camera is used to take pictures of vehicles within the monitoring field of view, and then a compression algorithm is used to make the image file smaller, and the image file is transmitted to the server. , the server uses the parsing image algorithm to analyze the image file, parses out the vehicle attributes, and then sends the parsed vehicle attributes to the database, and the database sends the information to the application software for query; the pixel of the camera is 3 million The above; the vehicle attributes include vehicle passing time, passing location, vehicle territory, license plate number, vehicle color, license plate color, vehicle speed, license plate picture and panoramic picture. In this way, the image recognition rate under bad weather conditions such as rainy and foggy conditions is improved, so ...

Abstract

The invention discloses an electronic view image identification method based on city signal visual perception. Due to combination between the information technology, the data communication transmission technology, the electronic sensing and controlling technology, the image processing technology and the embedded structure composed of lighting, a camera lens, a camera and a DSP circuit, the method can collect and identify images of vehicles and measure the speed of the vehicles, various information of the vehicles passing through a monitored area is recorded in real time and is stored, transmitted, analyzed and processed, the various vehicle information can be analyzed, the image identification rate under the situation of bad weather conditions such as rainy days and foggy days can be improved, and therefore safety of the vehicles within the monitored view range is monitored.

Description

technical field [0001] The invention relates to a recognition method of an electronic vision image based on visual perception of city signals, and belongs to the technical field of traffic information management systems. Background technique [0002] Intelligent transportation system is an important development direction of global road transportation in this century. The continuous development of highways, urban traffic, parking lots and other infrastructure construction levels and the continuous improvement of vehicle management systems provide opportunities for the practical application of computer vision-based intelligent traffic management systems. The domestic intelligent transportation system is still in its infancy. According to the requirements of the relevant state departments, it is gradually being promoted and used nationwide. The development direction of intelligent transportation system is video and portrait recognition and networked operation. Although some pl...
