基于图像处理技术的（Image-based processing technology） 4 Chinese science and technology of science and technology The fruit is of reference value for agricultural irrigation and fertilizing [35] It is. The canopy size is to determine the medium-term growth of rice A key factor, Singh measured the size of the canopy based on the rice image processing, and was used to judge water The growth of rice and the mathematical model of rice yield [36] It is. The application of image processing technology in agricultural automation in our country also has many, from recent years related The research progress is mainly manifested in the identification of crop deficiency symptoms, weed identification, crop group structure detection and so on There are few studies on automatic detection of crop development. Gui-li xu [37] Wait for an unmapped culture The color characteristics of the color image of the tomato nutrient elements are not easy to be found in the image To diagnose the lack of a certain or various nutrient elements, early judgment and appropriate measures to reduce the growth of crops Production losses. According to the characteristics of the color Hue (Hue) of the wheat field and the significance of wheat in the middle and late wheat fields, li The green area of wheat population is studied by combining image processing technology with artificial neural network technology (ANN) And the image recognition method of green leaf area is used to automatically diagnose wheat seedling. This method can also be used It is used to identify the characteristics of other crops such as rice and other crops, such as disease spots, plant type, appearance quality, etc [38] It is. Based on the observation and research of the location characteristics of plant in seedling stage, MAO wenhua proposed the computer vision The method of sensing technology DBW is divided and identified for the weeds in the seedling stage [39] It is. The technique of using digital image to detect cotton is not found in the
