[0002] Camellia oleifera is a kind of evergreen shrub or tree of theaceae, and is a main woody oil crop in China. Camellia oil is rich in nutrients, such as oleic acid and linoleic acid, and has a mellow taste, so it is a high-quality edible oil. Camellia oil is also a good industrial raw material, which can be used in soap, cosmetics and rubber industries.

[0003] As an important woody oil crop in China, the growth and development of camellia oleifera is significantly affected by phenology. Accurate grasp of the phenological stage of camellia oleifera is crucial for reasonable cultivation and management measures and improvement of camellia oleifera yield and quality. Traditional camellia oleifera phenology observation relies on regular field observation by manual observation. This method not only consumes a lot of manpower, time and energy, but also has strong subjectivity and limited observation frequency, so it is difficult to capture subtle changes and sudden situations of camellia oleifera phenology. With the development of internet and artificial intelligence technology, automatic observation of phenology gradually replaces manual observation.
