A highway intelligent analysis method based on conventional video

Abstract

The invention provides a highway intelligent analysis method based on conventional video. The method comprises the steps of: (1) background modeling: extracting front X frames of video and determininga fluctuation range of pixels; (2) image enhancement: reading images, performing histogram transformation and performing range extension on the gray scales of the images; (3) lane line detection; performing transformation processing on the images, performing add operation, traversing blank images and calculating the positions and angles of lane lines; (4) video speed measurement: defining two induction zones of vehicle detection, extracting the features of the vehicles and obtaining the real-time speeds of the vehicles via a virtual coil speed measurement algorithm; (5) statistics of trafficflow and vehicle type distinguishing analysis: judging the sizes of the vehicle types according to the pixel area of the vehicles in gray-scale maps and conducting statistics of traffic flow; (6) license plate number identification: if vehicles overspeed, identifying the license plate numbers of the overspeeding vehicles and outputting the license plate numbers to texts. The method increases the accuracy of lane line identification; the method can measure the speeds of target vehicles in multi-lane scenes and the implementation cost is low.

Description

technical field [0001] The invention belongs to the technical field of video processing, and relates to an intelligent analysis method for highways based on traditional video. Background technique [0002] Traffic intelligence analysis based on traditional video is a relatively active technical research direction in the field of computer vision / multimedia research in recent years. It allows the computer to imitate the process of human visual perception of object movement and judgment of events, and comprehensively uses image processing, pattern recognition, artificial intelligence and other technologies to analyze and understand real-time video signals or image sequences. It can well alleviate the problem of massive information redundancy in traditional video. [0003] The principles of expressway intelligent analysis technology are generally divided into two categories. One is based on the establishment of background models, mainly including behavior analysis within the bo...
