Advances in Research on Crop Nutrient Diagnosis Based on Image Processing

In recent years overuse of chemical fertilizer has become an increasingly prominent issue, and crop nutrition diagnosis based on image processing technology has been developed to solve this issue. The paper describes the research background of crop nutrition diagnosis, points out the significance of application of crop nutrient diagnosis based on image processing technology, and summarizes the overall situation and the basic ideas of crop image nutrition diagnosis. It also describes the technical methods and results of crop image acquisition, image preprocessing, feature extraction and optimization, classification and identification. The problems arising from the diagnosis of crop nutrition based on image processing are discussed, based on which the main directions of future research are proposed.
