Abstract

The invention relates to the technical field of artificial intelligence, in particular to a chemical enterprise safety risk early warning method and system based on visual perception. The method comprises the following steps: acquiring a fuzzy smoke image according to ambiguity features, and detecting the smoke image to obtain a key frame image and a danger weight of a smoke color in the image; obtaining a geometric center point of the smoke area, drawing a plurality of straight lines through the geometric center point, obtaining equal division points of each straight line to construct a polygon, and obtaining a volatility index of smoke according to a difference value of interior angles of the polygon; obtaining the diffusivity index of the smoke according to the offset of the coordinates of the geometric center point, and obtaining an energy characteristic difference value according to the energy characteristics of the smoke area; and acquiring the danger degree by a danger evaluation model constructed by the danger weight, the volatility index, the diffusivity index and the energy characteristic difference value. By constructing the polygon of the smoke area, the dynamic change characteristics and edge detail changes of the smoke can be quickly and accurately reflected, the prediction result of the danger degree can be reduced, and dangerous accidents are avoided.

Description

technical field [0001] The invention relates to the technical field of artificial intelligence, in particular to a method and system for early warning of safety risks in chemical enterprises based on visual perception. Background technique [0002] Fire detection is a research hotspot emerging in the field of pattern recognition and image processing in recent years. When a large-scale disaster accident occurs in a chemical enterprise, the degree of harm of the current accident is usually analyzed according to the color characteristics, shape characteristics and texture characteristics of the smoke that appears. [0003] At present, those skilled in the art reflect the shape change of the smoke by detecting the perimeter or area of ​​the smoke area, and then predict the severity of the fire. However, reflecting the shape change of the smoke according to the perimeter and area of ​​the smoke area will ignore the detailed change characteristics of the smoke, which will lead to...
