Embodiment 1

[0024] A method for generating a variable plant protection super-dimensional application prescription map provided by the present invention includes the following specific steps:

[0025] S1 to obtain spectral data: set a linear filter, the measured light from the measured object is irradiated on the linear filter, and the linear filter divides the measured light into multiple monochromatic lights arranged in parallel; and makes the linear The filter is imaged on the image sensor unit through the camera lens on the terminal to obtain the spectrum.

[0026] S2 Obtain field monitoring data: obtain field temperature and humidity, soil fertility, soil moisture meteorological data, etc.

[0027] S3 data preprocessing: Splice the collected aerial photography data, perform geometric correction after splicing, and perform radiation calibration, convert the DN value of the picture into reflectance, and finally save it as a TIFF file.

[0028] S4 Generate a preventive prescription map:...

Abstract

The invention discloses a variable plant protection super-dimensional pesticide application prescription map generation method, and the technical scheme is that the method comprises the following specific steps: S1, obtaining spectral data, S2, obtaining field monitoring data, S3, carrying out data preprocessing, S4, generating a preventive prescription map, S5, generating a fishing net grid, S6, assigning coordinates, S7, obtaining fishing net grid data, and S8, obtaining a variable plant protection super-dimensional pesticide application prescription map. The method has the advantages that in the actual operation process, the variable plant protection super-dimensional pesticide application prescription map is generated by means of accurate monitoring and analysis of nutrition and health conditions of field crops, material input is scientifically guided according to the variable plant protection super-dimensional pesticide application prescription map, differentiated plant protection operation, namely accurate variable plant protection, is carried out on the field crops according to the conditions of the crops. Therefore, the pesticide is scientifically and reasonably applied, the pesticide dosage is reduced, pesticide residues are reduced, and the crop phytotoxicity condition is reduced.

Description

technical field [0001] The invention relates to the technical field of drug application prescription map generation, in particular to a variable plant protection super-dimensional drug application prescription map generation method. Background technique [0002] Crops are various plants cultivated in agriculture. Including food crops and economic crops (oil crops, vegetable crops, flowers, grass, trees) two categories. "Food is paramount to man", which expresses the relationship between man and food, and a reasonable diet can bring health to human beings. The growth of crops is inseparable from scientific and technological production technologies, as well as machinery and equipment manufactured by new industries that can assist agricultural production. [0003] The prior art has the following deficiencies: in the existing current agricultural operation process, the plant protection operation is carried out by uniformly spraying in the field, and excessive application of pe...
