Periodic video recording method, device thereof, equipment and medium

Abstract

The invention provides a periodic video recording method and a device thereof, equipment and a medium. The method comprises the following steps: presetting a video recording period; and carrying out continuous sectional photographing and recording according to the photographing and recording period so as to continuously obtain an image data set which corresponds to each photographing and recording period and comprises a plurality of image data units, so that periodic storage and / or periodic transmission of the corresponding photographing and recording period is carried out aiming at each image data set or each image data unit. According to the video recording method provided by the invention, the core information in the image data can be simply and effectively acquired, and the characteristic of periodic sectional type shooting can be organically combined with periodic storage and periodic transmission, so that more core information can be stored in an unstable environment; and sufficient core information can be transmitted in real time and optimally, and the real-time video recording, storage and transmission process is more automatic, intelligent, effective and stable in a mutually coordinated manner.

Description

technical field [0001] The present application relates to the technical field of data recording, in particular to a periodic recording method, device, equipment and medium. Background technique [0002] In some application fields, it is necessary to automatically complete the real-time recording, storage, and transmission processes. But in some uncontrollable environments, how to automatically capture clear enough core useful information? [0003] For example, the focusing methods of existing cameras include: such as phase detection autofocus and contrast detection autofocus. But the phase detection, although its focusing speed is faster, but this detection mode will make the AF point focus on the middle of the picture; the principle of the contrast detection mode is to find the place with the highest contrast in the image to ensure that this place is the clearest of. But in order to do that, the lens has to move back and forth across the frame, which doesn't work well fo...

Problems solved by technology

More advanced cameras can reduce some of the total focus points, thereby increasing the speed of autofocus, or manually select a set of AF points, but more focus points will have an impact on the speed and accuracy of the camera's focus, the focus points themselves The accuracy and sensitivity of the
