Abstract
Description
technical field
[0001] The invention relates to the application of video detection technology in the traffic field, in particular to a method for real-time judging of road traffic conditions based on video monitoring images. Background technique
[0002] The identification of road traffic status is the basis for urban intelligent transportation system to release road condition information and guide traffic. At present, the identification of road traffic status is mainly based on the analysis and processing of floating car data, supplemented by a large number of video surveillance resources in the city to correct and supplement the road traffic status by means of manual observation. However, the accuracy of the traffic state discrimination algorithm based on floating car data is directly related to the number of floating cars and the operating status, so it cannot achieve high accuracy, and the method of manual observation and video monitoring has a very high impact on observ...
