Illegal building acquisition method and device based on image data

Abstract

The invention relates to an illegal building acquisition method and system based on image data, computer equipment and a storage medium. The method comprises the steps that a first building image anda second building image matched with the first building image are acquired, wherein each building image comprises multiple building sides; image alignment processing is performed on the second building image according to the first building image to acquire a third building image, wherein building sides in the third building image are in one-to-one alignment with the corresponding building sides inthe first building image; contour information of the building sides in the first building image and contour information of the building sides in the third building image are acquire respectively andcompared to acquire contour difference information; and an illegal building is determined according to the contour difference information. By the adoption of the method, the recognition efficiency ofthe illegal building and the timeliness of illegal building processing can be improved.

Description

technical field [0001] The present application relates to the technical field of information monitoring, in particular to a method, device, computer equipment and storage medium for acquiring illegal buildings based on image data. Background technique [0002] With the rapid development of my country's economy, the demand for land continues to grow. Illegal construction laws such as occupying cultivated land and encroaching on expressway construction control areas are gradually increasing, especially encroaching on expressway construction control areas. Cause visual impairment, affect the driver's driving judgment, and lead to an increase in the incidence of traffic accidents. At present, the identification of illegal buildings is mainly realized through patrolling by road administrators or self-reporting by the masses. These methods are often difficult to obtain real-time and accurate information on illegal buildings. The timeliness of material processing. Contents of the...
