Problems solved by technology

[0003] The existing road traffic flow statistics are usually implemented by pre-embedding pressure-sensing sensors on the road. This method needs to bury the pressure-sensing sensors synchronously during road construction, and the statistics may not be available due to the damage of the pressure-sensing sensors. , or due to the destruction of the pressure sensing sensor due to road renovation, it is impossible to carry out statistics, and the maintenance or replacement of the pressure sensing sensor requires digging the road surface, resulting in poor reliability of the existing road traffic flow statistics system, and difficult maintenance and high maintenance costs

Embodiment Construction

[0037] The technical solutions of the present invention are described below through specific embodiments. On the premise that there is no conflict with the purpose of the present invention, the embodiments mentioned below and the technical features in the embodiments can be combined with each other.

[0038] like figure 1 Shown, a kind of traffic statistics method based on video, wherein, comprise the following steps:

[0039] Step 1. Set up a detection area at a predetermined position on the road and collect video of the detection area;

[0040] Step 2, judging whether there is a vehicle target passing through the detection area according to the collected video;

[0041] Step 3. Count the passing vehicles according to the judgment result.

[0042] In the above technical solution, the statistics of the traffic flow of one or more lanes on the road are realized by checking whether there is a vehicle target passing through one or more detection areas specified in the video scr...

Abstract

The invention relates to a traffic flow statistic method based on a video. The method comprises the steps of determining a detection region on a predetermined position of a road and acquiring the video of the detection region, judging whether vehicle targets pass the detection region according to the acquired video, and counting the vehicles passing the detection region according the judgment result. By means of the technical scheme, a traffic flow monitoring system is realized based on the video and is independent of the infrastructure of the road, the system is stable and reliable, maintenance is convenient, maintenance cost is low, flow statistics of multiple lanes in the video can be achieved, and detection accuracy is high.

Description

technical field [0001] The invention relates to a traffic management method, in particular to a video-based traffic flow statistics method. Background technique [0002] Road vehicle volume statistics is an important basic information in traffic management information, which is closely related to road planning and traffic management, and has important significance in traffic management. [0003] The existing road traffic flow statistics are usually implemented by pre-embedding pressure-sensing sensors on the road. This method needs to bury the pressure-sensing sensors synchronously during road construction, and the statistics may not be available due to the damage of the pressure-sensing sensors. , or due to the destruction of the pressure sensing sensor due to road renovation, it is impossible to carry out statistics, and the maintenance or replacement of the pressure sensing sensor requires excavating the road surface, resulting in poor reliability of the existing road tra...
