Embodiment Construction

[0065] Below in conjunction with accompanying drawing, technical scheme of the present invention is described in further detail:

[0066] Such as figure 1 As shown, the present invention first comprehensively judges whether to call the daytime algorithm or the nighttime algorithm according to the brightness statistics of the current grayscale image and the system time; call the daytime algorithm during the daytime period; call the nighttime algorithm during the nighttime period. The time period judgment method is as follows:

[0067] In the system, set 7:00 in the morning to 17:00 in the afternoon as the daytime period, and 19:00 in the evening to 5:00 in the morning of the next day as the nighttime period. During the two time periods of day and night transition: between 5:00-7:00 in the morning and between 17:00 and 19:00 in the afternoon, count the average grayscale of the background image in the video frame in the previous 10 minutes every 10 minutes. If the average gray ...

Abstract

The invention discloses an all-weather urban vehicle tracking and counting method based on video monitoring. Two methods are respectively adopted after the current time interval is judged to be daytime or night; according to the technical scheme for daytime, a background removing method is used for extracting a foreground target of a vehicle and then whether a tracking method or a virtual detection line method is used for counting is judged according to congestion condition of the current road condition; and according to the technical scheme for night, a virtual detection line and a detectionregion are set firstly, then binarization processing is carried out on the current frame to extract car lamps, whether car lamps pass by is judged by scanning the detection line and counting is carried out. The method disclosed by the invention is applicable to all-weather traffic video monitoring, accurate tracking and reliable counting can be effectively carried out on the vehicles, and stability and robustness of traffic video analysis are improved.

Description

technical field [0001] The invention belongs to the field of intelligent traffic video monitoring, in particular to an all-weather urban video vehicle tracking and counting algorithm. Background technique [0002] In recent years, with the increase of people's vehicle ownership rate, Intelligent Transportation System (ITS) has occupied the most important position in many methods of improving transportation capacity, and has increasingly attracted the attention of researchers. Considering the requirements of the future development trend of transportation management, online monitoring and more detailed information collection in the traffic environment, image analysis and computer vision technology are quickly applied to traffic video analysis, in order to achieve such as vehicle volume statistics, thus Carry out functions such as congestion detection and traffic accident detection. Therefore, proposing a set of robust, real-time algorithms to process a series of traffic video...
