Intelligent and vision-based fire detection systems: A survey

Abstract

Fire is one of the main disasters in the world. A fire detection system should detect fires in various environments (e.g., buildings, forests, and rural areas) in the shortest time in order to reduce financial losses and humanistic disasters. Fire sensors are, in fact, complementary to conventional point sensors (e.g., smoke and heat detectors), which provide people the early warnings of fire occurrences. Cameras combined with image processing techniques detect fire occurrences more quickly than point sensors. Moreover, they provide the size, growth, and direction of fires more easily than their conventional detectors. This paper, initially, presents a glance view on the main features of various environments including buildings, forests, and mines that should be considered in the design of fire detection systems. Afterwards, it describes some of the intelligent and vision-based fire detection systems that have been presented by researchers in the last decade. These systems are categorized, in this paper, into two groups: intelligent detection systems for forest fires and intelligent fire detection systems for all of the environments. They use various intelligent techniques (e.g., convolutional neural networks, color models, and fuzzy logic) to detect fire occurrences with a high accuracy in various environments. Performances of the fire detection systems are compared to each other in terms of detection rate, precision, true-positive rate, false-positive rate, etc. under different evaluation scenarios.
