Embodiment 1

[0029] figure 1 It is a flowchart of a monitoring method for freezing damage in farmland provided by an embodiment of the present invention. The method can be implemented by a monitoring device for freezing damage in farmland, which can be implemented by software and / or hardware, and can be configured in a terminal and / or server to realize the monitoring method for freezing damage in farmland in the embodiment of the present invention.

[0030] Such as figure 1 As shown, the method of this embodiment may specifically include:

[0031] S101. Obtain an image of a target farmland to be monitored.

[0032] In a specific implementation, the farmer can use the input device to perform a circle selection operation on the visualized display images displayed in the farmer terminal, and determine the circled image as the target farmland image to be detected. It should be noted that the visualized display image may be a visualized image containing crop information in the target farmlan...

Embodiment 2

[0054] figure 2 It is a flow chart of another monitoring method for freezing damage in farmland provided by the embodiment of the present invention. This embodiment is optimized on the basis of the above-mentioned technical solutions. Optionally, based on the first normalized normalized vegetation index corresponding to each pixel position in the target farmland image and the target meteorological data, determine whether the target farmland area suffers from freezing damage, including: determining whether the target meteorological data is less than the preset meteorological threshold; if less than Preset meteorological threshold, then determine the rate of change of the first normalized normalized vegetation index relative to the historical normalized vegetation index of the pre-stored target farmland, and determine whether the rate of change is greater than the preset rate of change threshold; if greater than the preset rate of change threshold , it is determined that the t...

Embodiment 3

[0068] The corresponding embodiments of the monitoring method for freezing damage in farmland have been described in detail above. In order to make those skilled in the art more aware of the technical solution of this method, the scene of post-loan risk management and control based on the monitoring results of freezing damage in farmland is used below. As an example, further details are given.

Abstract

The embodiment of the invention discloses a farmland freezing damage monitoring method and device, electronic equipment and a storage medium. The method comprises the following steps: acquiring a to-be-monitored target farmland image; determining a first normalized vegetation index corresponding to each pixel position in the target farmland image based on a pre-stored satellite image; wherein the satellite image is an image containing crop information of the target farmland area; and obtaining target meteorological data of the target farmland area, and determining whether the target farmland area is subjected to freezing damage based on the first normalized vegetation index corresponding to each pixel position in the target farmland image and the target meteorological data. According to the technical scheme of the embodiment of the invention, whether the target farmland area is subjected to freezing damage can be determined without manual field investigation, the monitoring efficiency is improved, and the growth condition of crops can be quickly and accurately known.

Description

technical field [0001] The embodiments of the present invention relate to the technical field of image processing, and in particular to a monitoring method, device, electronic equipment and storage medium for freezing damage in farmland. Background technique [0002] With the rapid development of the rural economy, rural growers usually obtain financial support through bank loans to expand the scale of agricultural planting. After lending to rural growers, it is necessary to monitor the planting status of the crops. When the loaned agricultural land is damaged by low temperature and freezing, the farmers and the bank can be alerted respectively to prevent losses of farmers and reduce post-loan risks. [0003] At present, business personnel conduct on-site inspections manually to determine whether the crops in the loaned agricultural land area are damaged by low temperature freezing, so as to realize the monitoring of the planting conditions of the crops. However, it is inef...
