Abstract

The invention discloses a traffic video data acquisition method based on gray scale conversion. The traffic video data acquisition method comprises gray scale processing, traffic data acquisition andcongestion region identification. The method comprises the following steps: firstly, carrying out image acquisition on a traffic video according to the number of frames, carrying out graying processing on a color image by means of a weighted average method, then enhancing the gray level image according to a histogram equalization method, and carrying out binarization and noise reduction operationson the enhanced image to obtain a noise reduction image; Then, on the basis of the noise reduction image, in combination with an inter-frame difference value, identifying the vehicle passing throughthe detection line and obtaining traffic data; And finally, carrying out congestion region identification by means of vehicle speed, flow and time occupancy rate data. According to the method, the keytraffic data can be simply and efficiently obtained from the traffic video, the defects that the traffic video data occupies a large storage space and is difficult to analyze are avoided, and a certain guiding effect is achieved on identification of a traffic jam area.

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...
