The invention discloses a camera scene change detecting method based on the image angular point set characteristic. The camera scene change detecting method based on the image angular point set characteristic comprises the following steps that firstly, image angular point set information is obtained; secondly, an angular point set matching template is trained; thirdly, whether scene change occurs is judged. According to the camera scene change detecting method based on the image angular point set characteristic, the image angular point set information characteristic and the mathematical statistic probability template are combined to be used for judging whether scene change occurs within the monitoring range of a camera, and the image angular point set information is adopted ruing processing; compared with an existing method, only angular point information is adopted, the interference of pseudo angular points caused by accidental factors can be reduced, and the subsequent angular point matching is facilitated due to the fact that the angular point set information has the statistical probability stability; the overall angular point set probability matching template which is trained in advance is essentially manufactured according to statistical probability events in an angular point appearing area; in this way, the influence of the external accidental factors can be eliminated to a great extent, the method can be adapted to the practical engineering application environment, and the accurate detection effect can be achieved.
