Rice lodging not only affects the harvesting efficiency of the combine harvester, but also increases harvesting losses. When a combine harvester harvests lodging rice, it is necessary to adjust the operating parameters such as header height, reel position, and operating speed in a timely manner based on the morphological characteristics of the lodging rice. In order to reduce header loss and realize adaptive adjustment of header working parameters during harvesting of lodging rice, this paper proposes a characterization method of lodging rice morphology features, constructs a recogni-tion...
