%X The scanner and unmanned aerial vehicle(UAV) were adopted to take the leaf and canopy images,respectively.The images were corrected and applied to assess the rice nitrogen status on leaf level to canopy level by image analysis.The main results were as follows: 1) According to the analysis of relationship between the content of chlorophyll a and the color parameters,the effective color parameters were discovered as B,b,b/(r+g),b/r,b/g.The regression was carried out on leaf level based on the distinctive char...
