Abstract

Embodiments of the invention disclose a method and a device for detecting video dangerous cases. The method comprises: extracting foreground images of a video; performing preprocessing on the foreground images to obtain processed images; detecting a maximum connection region in the processed images; determining whether the maximum connection region has dangerous case hidden danger according to preset color information; if yes, performing dangerous case determination on the maximum connection region according to detection factors; and if the determination is passed, determining the video has dangerous cases. The method for detecting video dangerous case in a double manner through preset color information and detection factors realizes to detect dangerous cases in a video rapidly and accurately.

Description

technical field [0001] The invention relates to the field of video moving target detection, and more specifically, to a method and device for detecting video dangerous situations. Background technique [0002] With the development of my country's economy, there are more and more large high-rise and super high-rise buildings. KTV, nightclubs, saunas, boiler rooms, thermal power plants and other places have become an important part of society. All kinds of dangerous situations will happen at any time, and will directly endanger life, property and social stability. Once a large-scale disaster occurs, it will bring great disaster. Therefore, it is required to take effective measures to comprehensively monitor the dangerous situation before the large-scale disaster occurs, so as to prevent problems before they happen. However, the traditional sensor-based monitoring system is too expensive and wastes resources. Existing detection methods are mainly based on color, or gradient ...
