Embodiment Construction
[0051] The specific embodiment of the present invention will be further described below in conjunction with accompanying drawing:
[0052] refer to figure 1 , the embodiment of the present invention provides a kind of building change classification detection method, comprises the following steps:
[0053] S1. Acquiring a reference time-phase image map and a comparison time-phase image map;
[0054] In this embodiment, the detection is mainly aimed at the change of buildings in a certain area. The reference time-phase image map is the satellite image map taken in the previous year of the target detection area, and the comparison time-phase image map is the satellite image map taken at the current time. image map.
[0055] S2. Extracting the building outline from the reference time-phase image map and the comparison time-phase image map to obtain the building outline in the reference time-phase image map and the building outline in the comparison time-phase image map;

The invention discloses a building change classification detection method, system, device and storage medium. The method includes: extracting building outlines from a reference time-phase image map and a comparison time-phase image map to obtain the building outline in the reference time-phase image map. The building outline and the building outline of the comparative time-phase image map; calculate the SIFT eigenvalue of each building outline separately; according to the SIFT eigenvalue of each building outline, calculate the relationship between the corresponding building outlines in the overlay layer The matching degree; according to the matching degree, the building change classification result is obtained. According to the calculated matching degree, the present invention obtains the classification results of building changes, so that the present invention can work efficiently in a large scale and in a large range, and has high detection accuracy, which can effectively improve detection accuracy, greatly improve work efficiency, and greatly reduce manpower burden. The invention can be widely used in building change detection.
Description
technical field [0001] The present invention relates to the technical field of classification detection, in particular to a method, system, device and storage medium for classification detection of building changes. Background technique [0002] With the rapid development of urban construction, a very important task in the land supervision business is to supervise the construction, demolition, modification and expansion of buildings on the ground. If it is completely dependent on manpower, it will consume a lot of manpower, material resources and financial resources, and it will not be able to monitor the status quo of land resource utilization in an all-round way in real time. In recent years, remote sensing technology is generally used to detect changes in buildings, but the current detection methods have low precision and low accuracy, resulting in low work efficiency. Contents of the invention [0003] In order to solve the above technical problems, the object of the ...
