AI Technical Summary
Technical Problem
Existing methods for identifying changes in building areas suffer from low accuracy.
Method used
By acquiring remote sensing images and building vector maps, the building outlines are identified, enlarged, and segmented to determine whether the building outlines have changed.
Benefits of technology
It improves the accuracy of identifying areas of building change and overcomes the problem of misjudgment caused by the offset of building outline position in remote sensing images.

Abstract
The application provides a remote sensing image processing method, device and electronic equipment, the remote sensing image processing method comprises the following steps: acquiring a remote sensing image of a preset area and a first building vector diagram of the preset area; identifying a building contour in the remote sensing image, and acquiring a second building vector diagram; performing magnification processing on the building contour in the second building vector diagram to obtain a target building vector diagram; segmenting the target building vector diagram to obtain at least two to-be-tested subimages; and segmenting the first building vector diagram to obtain a reference subimage corresponding to each to-be-tested subimage; judging whether each to-be-tested subimage is an image in which a building contour changes based on the reference subimage, and outputting a target subimage in which a building contour changes. The application discloses a remote sensing image processing method, device and electronic equipment, and can solve the problem of low recognition accuracy of an existing building change area recognition method.
