Embodiment Construction

[0043] see image 3 , the present invention is mainly made up of computer, analog camera, video capture card and server, the video signal output of module camera is linked to video capture card, and server directly reads image data through the driver program of video capture card, then transmits to computer; Installed flame intelligent detection module: carry out the following detection steps:

[0044] 1), read the image sampled by the sensor;

[0045]2), preprocessing the image, including denoising and smoothing filtering;

[0046] 3), read the current status logo, if the logo is no flame detected, go to step 4, otherwise go to step 9;

[0047] 4), use the pixel-level processing method to divide the current observation image into binarized images, wherein the pixel mark that may be fire in the image is marked as 1, and the area that is not fire is marked as 0; the connected body algorithm is used to detect and mark as 1, and generate a linked list of detection results;

Abstract

The invention relates to an intelligent flame detector based on a computer vision monitoring technology, which mainly comprises a computer, an analog camera, a video capture card and a server. The video signal output of the analog camera is linked with the video capture card, and the server directly reads image data through driving program of the video capture card and transmits the image data tothe computer; and an intelligent flame detection module is arranged in the computer. The invention realizes the detection based on visual features of the flame, and aims to realize tracking and filtering in a visual tracking method when the existence of the flame is determined, and the determined position of the flame in the image center is obtained through camera calibration and multi-source camera image fusion, so as to guide automatic fire-extinguishing of fire-extinguishing equipment. The invention has the advantages of rich video information, accurate splitting, no site limitation, smallexternal interference, and precise flame positioning.

Description

technical field [0001] The invention belongs to an automatic target detection and recognition device based on video technology, in particular to an intelligent flame detection device based on a video sensor. Background technique [0002] A single spark can start a prairie fire. Fire accidents are extremely destructive, usually causing very serious damage to people's material property and life safety. However, fires are usually started by small-scale ignition sources that are not contained in time. Therefore, it is of great social and economic significance to study how to automate early detection and early warning of fires. The traditional way to prevent fires is to use smoke detectors. At present, smoke sensors have been widely installed in key areas of buildings and have become a standard measure for building fire protection. Strictly speaking, however, a smoke detector is a sensor that detects specific smoke particles and does not directly detect flames. Only when thi...
