Problems solved by technology

[0004] The existing technology saves the monitoring video at every moment to storage devices such as hard disks and video tapes in real time for subsequent retrieval and review, but the monitoring video files generated in this way require a large storage space, which leads to monitoring equipment. In the case of limited storage space, only a short duration of surveillance video can be stored

Abstract

The invention provides monitoring video file generation and playing methods and devices and terminal equipment. The monitoring video file generation method comprises the steps of: acquiring a real-time video frame shot by a monitoring camera; inquiring a prior video frame consistent with the real-time video frame in a de-duplicated video frame set; if the prior video frame consistent with the real-time video frame is not inquired, storing the real-time video frame into the de-duplicated video frame set, and recording a mapping relationship between playing time and the real-time video frame ina playing index; if the prior video frame consistent with the real-time video frame is inquired, abandoning the real-time video frame, and recording a mapping relationship between the playing time andthe prior video frame in the playing index; and according to the de-duplicated video frame set and the playing index, generating a monitoring video file. According to the invention, a size of the monitoring video file can be reduced, and duration of a storable monitoring video is prolonged.

Description

technical field [0001] The invention relates to the technical field of information security, in particular to a monitoring video file generation and playback method, device and terminal equipment. Background technique [0002] As a social security system, video surveillance system has been widely used in daily life. Video capture equipment such as cameras can be seen everywhere in banks, shopping malls, supermarkets, hotels, street corners, intersections, toll stations and other public places. The installation of this type of system has greatly increased social security, played a role in real-time monitoring and recording of the behavior of criminals, and provided a large number of real and reliable clues for the public security organs to detect cases. [0003] Existing video surveillance systems store surveillance videos in a way that generally records videos recorded by cameras in real-time and completely in a database. For general video surveillance application scenarios...
