Abstract: Smoking in public places seriously harms people’s health and even life and property safety, so real-time and efficient smoking detection is of great significance. At present, smoking detection based on computer vision has gradually become the mainstream method with the advantages of high efficiency and high precision. On the basis of a brief overview of non-computer vision smoking detection methods, three kinds of detection methods based on computer vision are summarized. Firstly, the extraction methods of smoke features such as color, appearance and movement are discussed. Secondly, two methods of extracting cigarette target based on single step and multi-step target detection are introduced. Finally, different types of smoking action feature extraction methods are discussed from the perspectives of artificial feature construction and deep learning feature extraction. The above methods are analyzed and summarized, and the future research direction is prospected.
