| titleOfInvention | Automatic recognizing method and device for nitrogen phosphorus and potassium stress of protected tomatoes |
| abstract | The invention relates to an automatic recognizing method and device for nitrogen phosphorus and potassium stress of protected tomatoes. The automatic recognizing device consists of a CCD (charge coupled device), a spectrograph, an optical system, a light source, a displacement platform, a controller, a PC (personal computer), a display and a light box. The method comprises the following steps of: firstly, performing system experiment calibration on the automatic recognizing device by a calibrating sample; then sampling a model sample during a whole growth period at equal time intervals, and collecting the reflection intensity, the polarization distribution and hyper spectrum image information of visible light-near infrared of inverted-7-shaped leaves of the tomatoes; analyzing and acquiring a main ingredient image of a nutrition stress sample according to main ingredients by combining with a measured value of chemical nitrogen phosphorus and potassium analysis and a micro structure scanning electron microscope test of the model sample, thus determining the characteristic wavelength of nitrogen phosphorus and potassium; and classifying nutrition stress characteristics into three types including a polarization characteristic, an intensity characteristic and an image characteristic, establishing the characteristic space of the nutrition stress characteristics, and establishing an automatic recognizing and comprehensive evaluation model for nitrogen phosphorus and potassium of the tomatoes according to a D-S (Dempster/Shafer) criterion theory, thus automatically recognizing and diagnosing the nitrogen phosphorus and potassium stress types of the protected tomatoes. |
