Abstract

The invention discloses a fire fighting lane occupation abnormal object detection method based on an inter-frame difference method. The method comprises the following steps: acquiring a grayscale image of a picture in a fire fighting lane occupation detection area in a normal state as a base image; and then, sequentially acquiring a camera video frame, comparing the camera video frame with the base image, acquiring a foreground object shape by utilizing an inter-frame difference method, acquiring the minimum outer frame coordinate of the object according to morphology, and performing abnormalobject detection and abnormal condition report judgment in the fire-fighting lane occupation detection area according to the acquired minimum outer frame and fire-fighting lane occupation detection information base. The fire fighting lane occupation abnormal object detection method based on the inter-frame difference method is simple in algorithm implementation, low in program calculation complexity, high in operation speed and insensitive to scene light change, and the detection accuracy can be improved. The fire fighting lane occupation abnormal object detection method based on the inter-frame difference method has the advantages of being simple in algorithm implementation, low in calculation complexity and high in operation speed.

Description

technical field [0001] The invention relates to the technical field of detection of abnormal objects in fire-fighting lanes, in particular to a method for detecting abnormal objects in fire-fighting lanes based on an inter-frame difference method with simple algorithm implementation, low computational complexity and fast operation speed. Background technique [0002] With the development of smart security, more and more intelligent applications are implemented in the actual construction of smart security, especially the warning event monitoring and early warning applications in special areas, which play an important role in the construction and development of smart communities, such as Applications such as fire occupancy and climbing alarms make the work of community security management more intelligent and digital, and monitor and monitor abnormal conditions in special areas for people and vehicles entering and leaving the community. As for the detection of fire-occupied la...
