Embodiment 1

[0050] The present embodiment provides a kind of meteorological automatic observation system of crops, such as Figure 2-6 Shown, comprise crop meteorological automatic observation station 10, provincial central station 40 and national comprehensive meteorological information sharing platform 30, the signal end of crop meteorological automatic observation station 10 is connected with the signal end of provincial central station 40, and provincial central station 40 The signal end of the national comprehensive meteorological information sharing platform 30 is connected to the signal end; the crop meteorological automatic observation station 10 includes an image sensor 102, an image collector 101 and peripheral equipment 104, and the image sensor 102 is connected with the image collector 101, and the image collector 101 Also connected to peripheral device 104 .

[0051] As a preferred embodiment, the crop weather observation station 10 also includes a video sensor 103 .

[0052...

Embodiment 2

[0064] The present embodiment provides the automatic meteorological observation method for crops, such as figure 1 As shown, the method includes:

[0065] Collect crop images, identify crop types according to the crop images, and the crop types include rice, wheat, corn, cotton, rapeseed, soybean and sugarcane;

[0066] Continuously acquire image information of crops, analyze the image information acquired at different time nodes, and judge the characteristic types of crops respectively, which include crop development period, coverage, density, canopy height, growth status evaluation, leaf Area index and dry matter weight;

[0067] Analyze and compare each feature type to determine whether the feature type is in a normal state.

[0068] Further, when judging the crop development period of the crop, first judge the type of the crop according to the image of the crop;

[0069] When the crop type is rice, the development period of the crop includes the transplanting period, th...

Embodiment 3

[0092]In this embodiment, on the basis of Embodiment 1 and Embodiment 2, the image information or video information collected by the image collector 101 of the present embodiment is transmitted to the provincial central station 40 and the national comprehensive weather information sharing platform 30 through the network for analysis judge. This embodiment can automatically identify agricultural meteorological disasters based on image data, meteorological data and artificially assisted observation data. Agricultural meteorological disasters are divided into dominant disasters with obvious symptoms of crop damage and can be identified through image analysis, and hidden disasters with no obvious symptoms of crop damage and difficult image recognition. Dominant disasters mainly include: drought, windy lodging, hail disaster; hidden disasters mainly include: waterlogging, continuous rain, low temperature and chilling damage, frost, freezing damage, snow disaster, high temperature h...

Abstract

The invention discloses an automatic meteorological observation method for crops. The method comprises the following steps: collecting a crop image, and recognizing the types of crops according to thecrop image, and the types of crops comprise rice, wheat, corn, cotton, oilseed rape, soybean and sugarcane; continuously acquiring image information of the crops, analyzing the image information acquired at different time nodes, and respectively judging characteristic types of the crops, the characteristic types including crop development period, coverage, density, canopy height, growth conditionevaluation, leaf area index and dry matter weight; and analyzing and comparing each feature type, and judging whether the feature type is in a normal state or not. The problem that existing agricultural production is poor in meteorological observation capacity is solved, continuous observation of crop growth can be achieved, the working efficiency is improved, the objectivity of observation datais enhanced, personal errors are reduced, and the timeliness and pertinence of services are improved.

Description

technical field [0001] The invention relates to the technical field of agricultural informatization, in particular to an automatic meteorological observation method and system for crops. Background technique [0002] With the rapid development of electronic information technology, the era of combining agriculture and electronic information is getting closer. Existing agriculture already has large-scale machinery and monitoring systems for auxiliary operations. But the existing agriculture cannot observe and monitor agricultural meteorology. Therefore, enhancing the ability of agricultural meteorological observation is the need of my country's agricultural production, disaster prevention and mitigation, and meteorological development in the new century and under the new situation, and it is also the need of modern meteorological business development. Contents of the invention [0003] The purpose of the present invention is to overcome the deficiencies in the prior art, p...
