Abstract

The invention discloses a traffic video data acquisition method based on grayscale conversion, which includes grayscale processing, traffic data acquisition and congestion area identification. Firstly, the traffic video is acquired according to the number of frames, and the color image is grayscaled with the weighted average method, and then the grayscale image is enhanced according to the histogram equalization method, and the enhanced image is binarized and denoised. To obtain a noise-reduced image; then, based on the noise-reduced image, combined with the inter-frame difference, identify the vehicle passing the detection line and obtain traffic data; finally, use the data of vehicle speed, flow, and time occupancy to identify the congestion area. The invention can simply and efficiently obtain key traffic data from traffic videos, avoids the disadvantages of large storage space occupied by traffic video data and difficult analysis, and has a certain guiding effect on the identification of traffic congestion areas.

Description

technical field [0001] The invention belongs to the field of intelligent transportation, and relates to a method for acquiring traffic video data based on grayscale conversion. Background technique [0002] With the continuous development of the city, the number of motor vehicles is increasing year by year, which has caused huge traffic pressure on the limited urban space. Traffic is a real-time dynamic process. To alleviate various current traffic problems, a large amount of real-time data is needed. High-quality dynamic traffic information reflects the real-time traffic operation status and evolution trend, which is conducive to the management department to formulate more efficient management measures in time to ensure the safety and smoothness of traffic operation. As an important way to obtain real-time traffic information, traffic video detection technology has been widely used for its intuitiveness and comprehensiveness of information. [0003] However, as an importan...
