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.
