A law enforcement recording system and method based on feature marks and audio and video analysis and recognition

Abstract

The invention discloses a law enforcement recording system and method based on feature marks and audio and video analysis and recognition, the system comprises a law enforcement recorder, the law enforcement recorder is provided with a shooting device, and the shooting device is used for shooting audio and video and the combination of the feature marks to form an audio and video file; The system further comprises a background application service system, and the background application service system is provided with an audio and video feature mark identification unit and an audio and video fileprocessing unit. Wherein the audio and video feature mark identification unit is used for identifying information contained in a feature mark in the audio and video file; And the audio and video fileprocessing unit is used for carrying out unique association on the identified feature mark and the audio and video file. By adopting the technical scheme of the invention, law enforcement officers are very convenient to use, and shot audio and video files are all processed by the background application service system located at the background. Therefore, the method has wide practical requirementsin governments adopting law enforcement records and other industries.

Description

technical field [0001] The invention belongs to the technical field of law enforcement equipment, in particular to a law enforcement recording system and method based on feature marks and audio and video analysis and recognition. Background technique [0002] From the way of formation, QR codes can be divided into two categories: [0003] (1) Stacked two-dimensional code: on the basis of one-dimensional barcode, multiple barcodes are stacked together for encoding. Common encoding standards include PDF417, etc.; [0004] The other is the matrix two-dimensional barcode represented by QR. [0005] (2) Matrix two-dimensional code: In a matrix space, information is represented by black and white squares, black squares represent 1, white squares represent 0, and the corresponding combination represents a series of information, common coding There is a QR code as standard, [0006] At present, many applications use QR codes for encoding and decoding. QR codes not only have large...

Problems solved by technology

In actual use, the video of the law enforcement recorder can be leaked and disseminated to unauthorized Internet, WeChat, Weibo and other media by directly playing back photos, audio and video files, and recording files in the law enforcement recorder, and has been Leaked resources cannot be traced back to the source through effective means; once the photos, audio and video files, and recording files of the law enforcement recorder are collected on the collection workstation or saved in the storage setting, they can be processed at will, copied and cut; law enforcement records can be operated independently By the time the instrument was released, the video could be remade and leaked irretrievably

During the use of the law enforcement recorder, since the memory card can be hot-swapped, the video files stored in the memory card may also be deleted or modified at will.
