Abstract

The invention discloses a snapshot method and device, electronic equipment and a storage medium. The method comprises: acquiring a target visible light image and a target infrared image of a snapshotarea; determining a fusion image according to the pixel value of each pixel point in the target visible light image and the pixel value of each pixel point in the target infrared image; and accordingto a set snapshot target, identifying a target area matched with the snapshot target in the target visible light image and the fusion image, and replacing the image of the target area in the fusion image with the image of the target area in the target visible light image to obtain a snapshot image. The method and the device are used for ensuring that the dynamic range of a snapshot image is increased and the resolution on a local target area is not reduced, so that the visible content of the snapshot image in visibility is increased, the local target area is clear and clean, and the quality ofthe snapshot image is improved.

Description

technical field [0001] The present invention relates to the technical field of image processing, in particular to a snapshot method, device, electronic equipment and storage medium. Background technique [0002] With the continuous development of science and technology and the increasing importance of security monitoring, more and more functions are integrated on the camera equipment. The existing camera equipment can collect video images in real time, and can also be based on the On the road, capture the passing pedestrians, vehicles, etc. However, it is easily affected by natural factors such as lighting conditions. When there are strong light sources such as sunlight, reflections and other bright areas, and dark areas such as shadows and backlighting, the visible light images captured by the camera equipment will appear white due to overexposure, and dark areas. The area becomes black due to underexposure, that is, the captured visible light image has limitations in brig...
