Embodiment 1

[0078] The specific implementation of this patent is explained by taking the video intelligent identification and monitoring of fire smoke caused by the leakage of the tank area of ​​the refinery plant as an example.

[0079] Step 1: Determination of static characteristics of fire smoke

[0080] First, the current frame image is obtained through the collection and input of video images, and then the irregular characteristics of the fire smoke boundary area and the gray uniformity of the fire smoke area are delineated at the same time, and the determination of whether there is a suspicious fire smoke area is carried out.

[0081] The specific determination method is as follows:

[0082] Fire smoke will show an obvious tendency to diffuse during the combustion process, resulting in obvious irregularities in the outline of the smoke. Moreover, the perimeter of the fire smoke boundary is significantly larger than the perimeter of the circle under the same area. Using the characteristic o...

Abstract

The invention discloses a fire smoke video intelligent monitoring and early warning system and method, and relates to the technical field of fire smoke monitoring of chemical plant areas. The system comprises a main server and an analysis processing module, wherein the analysis processing module analyzes a video image in the main server, and defines a suspicious smoke range by utilizing the staticcharacteristics of fire smoke in the video image, so that the suspicious smoke region is determined by adopting the dynamic characteristics of the smoke in the video image. When the video image showsthat the fire smoke boundary area is irregular or / and the gray value of a pixel point exists in the fire smoke area, the fire smoke boundary area is delineated as the suspicious fire smoke area underthe static characteristic. According to the method, in the process of delineating the suspicious fire smoke region, the irregular characteristic of the boundary of the fire smoke region and the characteristic of regional gray scale uniformity are comprehensively considered, so that the suspicious fire smoke region can be more effectively and accurately delineated.

Description

Technical field [0001] The invention relates to the technical field of fire smoke monitoring in a chemical plant area, in particular to a fire smoke video intelligent monitoring and early warning system and an early warning method. Background technique [0002] In the chemical plant area, the equipment process is complicated, the materials are dangerous, and there is a high temperature and high pressure production environment in the production process, which is prone to combustion and explosion of chemical raw materials and leakage. Relevant data show that fires and explosions are the most important factors causing casualties and property losses in the chemical plant area. Therefore, real-time monitoring, identification and early warning of the smoke generated in the early stage of fire in the chemical plant area is of great significance to prevent fire and explosion accidents in the chemical plant area. At present, traditional fire detectors mainly monitor and give early warnin...
