Autonomous Fire Extinguisher System Using Matlab Video Processing And Pic
Résumé: The aim of this project is to implement a system to detect, localize, and extinguish fire threats. It is designed for factories or urban residential. It is an optical autonomous image processing fire extinguisher. It consists of three main parts: a camera, a computer, and a PIC microcontroller. The camera is used to monitor the zone to be protected. We developed an algorithm that analyses real time stream images to detect flame sources. We used Matlab image processing toolbox to implement a technique that combines RGB and YCbCr color spaces to search for fire pixels. The processed data is then sent to a PIC microcontroller which drives two stepper motors to control the aiming angle of a water cannon. An infrared flame sensor is fixed on the cannon to detect fire emitted radiation. The flame sensor is used as a confirmation tool before water shooting to avoid false alarms. We managed to achieve a simulation and a functional implementation of the above system. The system was put to the test under different conditions to find its weaknesses. It showed great response in the presence of other light sources than fire flames in the background. Even though it sometimes was triggered without any flame in the scene, the infrared flame sensor prevented the system from enabling the water cannon and the false alarm was ignored.
