Design Scheme of Fire Monitoring System Based on MATLAB
As people's requirements for quality of life are getting higher and higher, safety issues are becoming more and more important. Fire is an extremely dangerous natural disaster, which will cause great casualties and material property losses when it occurs. In order to protect people's life safety and property safety, it is particularly important to design a fire monitoring system based on MATLAB. Let's introduce the system we designed.
- System Design Ideas
This system is mainly designed and developed based on the MATLAB software platform. It collects real-time images through the camera, uses MATLAB for data processing and image recognition, detects whether there is a fire source in the scene, and timely alarms, so as to achieve the purpose of fire prevention. The specific process is as follows:
- Implementation steps
(1) Collect real-time images
Use the Image Acquisition Toolbox of MATLAB to obtain the video stream of the real-time picture by connecting the camera. code show as below:
vid = videoinput('winvideo', 1, 'YUY2_640x480');
preview(vid);
(2) Perform image processing
For each frame of image collected, steps such as image preprocessing, binarization, and noise filtering are performed to obtain a processed grayscale image. code show as below:
videoFrame = getsnapshot(vid);
grayImage = rgb2gray(videoFrame);
binaryImage = imbinarize(grayImage);
filteredImage = medfilt2(binaryImage, [5 5]);
(3) Fire source detection
