Problems solved by technology
[0003] In the prior art, although based on the video monitoring equipment, the video monitor can monitor the monitored scene in real time, but in some cases, it may be difficult for the video monitor to monitor the video all the time, or the video monitor needs to monitor many videos , it is difficult to take into account each video in real time, and some events that have occurred may be missed
If criminals quietly place stationary dangerous goods such as timed explosives in a place that can be photographed by the video camera, but the public security management personnel fail to detect and stop the illegal acts of criminals in time, which will lead to disasters. so that the people or collectives suffer losses

Embodiment Construction
[0052] In the present invention, in order to make it easier for video monitors to know some events in the monitored scene in a timely manner, a technical solution mainly for monitoring static scenes is provided, which specifically includes: for images captured by a fixed camera, by comparing and detecting frame images With the reference frame image, obtain the still area candidate image of the scene to be determined as the still area; then, match the still area candidate image with the preset still area reference image, if the still area candidate image is similar to the still area reference image If the performance is good and the preset similarity conditions are satisfied, the scene shown in the still area reference image or the still area candidate image can be determined as a still scene, and the still area reference image and / or the still area candidate image can be marked as the still area image .
[0053]In practical applications, after the image of the still area is ma...

The embodiment of the invention provides a static scene calibration method, including: inter-comparing the testing frame image and reference frame image to obtain static zone candidate image whose represented scene is indeterminate as static scene; performing matching process to the static zone candidate image and the preset static zone reference image, calibrating the static zone reference image and the corresponding static zone candidate image as static zone images representing the static scenes if the similarity between the static zone candidate image and the static zone reference image satisfies the preset similar condition. The embodiment of the invention also provides a static scene calibration device. The technical scheme provided the embodiment of the invention can automatically calibrate the static zone images, which helps video observer to quickly and accurately discover the static objects under monitoring scenes.
Description
technical field [0001] The present invention relates to the technical field of image processing, in particular to a calibration method and device for still scenes. Background technique [0002] In real life, in some environments, a video monitor may monitor the scene captured by a fixed video camera, so as to keep abreast of what is happening in the monitored scene. For example, public security management personnel usually use video surveillance equipment to monitor the jurisdiction area under management, so as to eliminate potential safety hazards in time and ensure the safety of the jurisdiction area. [0003] In the prior art, although based on the video monitoring equipment, the video monitor can monitor the monitored scene in real time, but in some cases, it may be difficult for the video monitor to monitor the video all the time, or the video monitor needs to monitor many videos , it is difficult to take into account each video in real time, and some events that have ...
