摘要

•RGFI derived from UAV RGB images was designed to classify experimental field.•A better sample size for GMM threshold method was determined.•BSfM with higher accuracy was proposed to estimate the height of potato plants.•The prescription map of potato ridging was generated based on the plant height.
