Abstract

The invention provides a remote sensing cultivated land change detection method based on an object map and a mixed spectrum. The remote sensing cultivated land change detection method comprises the following steps: step 1, acquiring synchronous remote sensing image data of at least five years; step 2, constructing an object map of the image according to the remote sensing image data; wherein the construction process comprises data preprocessing, image segmentation, feature extraction and image classification; step 3, performing mixed spectrum analysis on the object spectrum; and step 4, detecting the change of the cultivated land through superposition analysis. According to the invention, the difference characteristics of a cultivated land object map and the differentiation characteristicsof mixed spectrum calculation are combined; a corresponding knowledge rule structure is established according to the evolution characteristics of the cultivated land change type, the change of the cultivated land and other ground object types in the change process is described, the detection precision of cultivated land change details is improved, the precision of the whole remote sensing cultivated land change detection method is further improved, and the adaptability of the new detection method is better.

Description

technical field [0001] The invention belongs to the technical field of remote sensing image detection, and in particular relates to a remote sensing cultivated land change detection method based on an object map and a mixed spectrum. Background technique [0002] With the rapid economic development, increased pollution, population growth and many other reasons, the world is facing food security issues such as the reduction of cultivated land and the decline of soil quality. Therefore, protecting cultivated land is an important task in the process of promoting the realization of food security; then, can Efficient and accurate detection and grasp of changes in cultivated land conditions will have important guiding significance for the precise control of changes in land resource types and land resource development planning. [0003] Traditional cultivated land change detection relies on cultivated land monitoring. This method has problems such as heavy workload, high cost, long...
