Abstract: The identification of tender tea leaves and the extraction of picking position parameters are prerequisites for intelligent tea harvest. This article first analyzed the overall scheme of tea mechanical picking and the feasibility of obtaining picking position by the tea image. Then extracted the minimum enclosing rectangle of each tea shoot in the binary image and labeled the center of the minimum enclosing rectangle as the picking position of the tea shoot. So the position parameters of tea picking were obtained， which provided the basis for subsequent intelligent picking of tea.

Key words:  intelligent tea picking, tea image, position parameter, the minimum enclosing rectangle
