Cultivated land image extraction method and equipment

Abstract

The invention discloses a cultivated land image extraction method and device, and the method comprises the steps: determining a remote sensing image of a to-be-detected region, obtaining the basic information of the remote sensing image, and enabling the basic information to at least comprise time information and space information; determining a plurality of identification models pre-stored in a database, and obtaining matching degrees between the remote sensing image and the plurality of identification models according to the basic information of the remote sensing image; performing edge detection analysis on the remote sensing image of the to-be-detected area, and dividing the remote sensing image of the to-be-detected area into a plurality of to-be-determined areas; the identification model with the highest matching degree is selected to identify the land types of the plurality of to-be-determined areas, and image tags corresponding to the land types of the plurality of to-be-determined areas are generated; determining whether the to-be-determined area is a cultivated land area according to the image label; and if yes, extracting a remote sensing image corresponding to the to-be-determined area as a cultivated land image of the to-be-detected area. The process of extracting the cultivated land image through the remote sensing image is more detailed, and the accuracy and precision are improved.

Description

technical field [0001] This application relates to the field of cultivated land protection, in particular to a method and equipment for extracting cultivated land images. Background technique [0002] Cultivated land protection refers to the protection of the quantity and quality of cultivated land by using legal, economic, technical and other means and measures. If the area of ​​arable land is greatly reduced, it will directly threaten the development of agriculture. For this, we must secure a certain amount and quality of arable land. In order to use cultivated land resources reasonably and effectively, it is first necessary to use remote sensing technology to complete the revision of the overall land use plan and the census of the quantity and quality of cultivated land. However, at present, the accuracy of extracting cultivated land images through remote sensing technology is not high, and misjudgments, errors and omissions are prone to occur. Therefore, there is an u...
