As a kind of chemical information, odor is ubiquitous in life. Therefore, the research of artificial olfaction technology has far-reaching strategic significance and wide application scope. This paper firstly introduces the concept and definition of artificial olfactory perception technology, and compares the development of artificial olfactory technology of bionic type and chemical analysis type with related researches; meanwhile, the research work of Olfactory Computing Group in artificial olfaction and olfactory computing is used as a case study to further elaborate the development trend from artificial olfactory technology to olfactory computing technology in this field. In addition, this paper illustrates the current technical challenges and possible solution paths of olfactory computing research, as well as the prospect of landing applications of olfactory computing in smart home, smart agriculture, medical health and other industries. The huge potential value of odor information in real environment has not been fully explored, so the research of artificial olfaction technology for different application scenarios may become an important research topic in the future.
