Embodiment 1

[0017] Such as figure 1 Shown is a flow chart of a method for monitoring dangerous goods vehicles at a traffic intersection provided by the first embodiment of the present invention. For ease of description, only the parts related to the embodiment of the present invention are shown.

[0018] In step S101, a video stream is collected, and the video stream is converted into continuous frame images.

[0019] In the embodiment of the present invention, firstly, a camera set up at a traffic intersection captures vehicle traffic conditions at the intersection, and collects video streams of vehicle traffic. Then, convert the captured video stream into continuous frame images for subsequent processing.

[0020] In step S102, after scene calibration and foreground extraction are performed on the current frame image, it is detected whether the foreground information of the current frame image contains a solid-color square area or a circular area danger sign, and if so, an alarm messag...

Embodiment 2

[0058] figure 2 The structural diagram of the device for monitoring dangerous goods transport vehicles at traffic intersections provided by the embodiment of the present invention, for the convenience of description, only shows the parts related to the embodiment of the present invention.

[0059] In the embodiment of the present invention, the device for monitoring dangerous goods transport vehicles at traffic intersections includes:

[0060] An image acquisition unit 21, configured to acquire a video stream, and convert the video stream into continuous frame images;

[0061] The danger monitoring unit 22 is used to detect whether the foreground information of the current frame image contains a solid-color square area or a circular area danger sign after performing scene calibration and foreground extraction on the current frame image, and if so, output an alarm message.

[0062] Wherein, the danger monitoring unit 22 includes five subunits, respectively:

[0063] The scen...

Abstract

The invention belongs to the field of video monitoring and provides a method and device for monitoring dangerous goods transportation vehicles at a traffic intersection. The method includes the steps that video streaming is collected and is converted into continuous frame images; after scene calibration and foreground extraction are performed on the image of the current frame, whether the foreground information of the image of the current frame contains a pure square area dangerous mark or a pure round area dangerous mark is detached, and then warning information is output. The method and device for monitoring the dangerous goods transportation vehicles at the traffic intersection can accurately and effectively judge whether dangerous goods transportation vehicles appear in shot vehicle passing videos, and do not need manual video detection, so the labor cost is greatly lowered; in addition, the requirements for processing capacity of hardware equipment are low, so the investment cost of the hardware is low, and the method and device can have wide applicability.

Description

technical field [0001] The invention belongs to the field of video monitoring, in particular to a method and device for monitoring dangerous goods transport vehicles at traffic intersections. Background technique [0002] In the field of intelligent transportation, intelligent video surveillance plays an increasingly important role. In some important areas, it is absolutely forbidden for vehicles transporting highly toxic, explosive, flammable, radioactive and other dangerous goods to enter or pass through. If a vehicle transporting dangerous goods has an accident in such an area, it will cause a catastrophic accident. How to monitor and manage such vehicles transporting dangerous goods is a major challenge for traffic management departments. [0003] There are three traditional methods of handling: first, set up traffic checkpoints, and manually detect whether the vehicles are transporting dangerous goods. However, considering the labor cost, it is impossible to set up hu...
