Hard disk recorder with human face image capturing function and method for capturing a human face image

Abstract

The invention discloses a hard disk recorder with human face image capturing function and a method for capturing a human face image. The hard disk recorder comprises a human face image capturing system. The human face image capturing system comprises an image acquisition unit, a first storage unit, a human face real-time comparison unit, an image real-time screening unit, a second storage unit and a human face afterward comparison unit, wherein the image real-time screening unit screens a human face image in the first storage unit according to the similarity calculated by the human face real-time comparison unit, and keeps only one human face posture image for the same person. The human face afterward comparison unit selects human face images which have similarities, with human face images set in the second storage unit, smaller than the set similarity, and stores the human face images into the second storage unit. The hard disk recorder and the method directly complete acquisition work of human face photographs, reduce workload of manually playing back, screening and capturing.

Description

technical field [0001] The present invention relates to a hard disk video recorder, in particular to a hard disk video recorder with the function of capturing human face images, and at the same time relates to a method for capturing human face images of the above hard disk video recorder. Background technique [0002] In reality, some key places need to monitor and store images, and DVRs are usually selected for video storage. However, traditional DVRs have the following problems: [0003] 1. The traditional hard disk video recorder produces about 850MB of video per hour, and the video stored for three months is about 1793GB under normal circumstances. The stored video recordings take up a lot of hard disk space; it is often necessary to export data from the hard disk or add a new hard disk; [0004] 2. The utilization rate of video recording is low, and manual video playback is often required, and photos are intercepted again for use; while wasting hard disk space, a lot o...

Problems solved by technology

The stored video recordings take up a lot of hard disk space; it is often necessary to export data from the hard disk or add a new hard disk;

[0004] 2. The utilization rate of video recording is low, and manual video playback is often required, and photos are intercepted again for use; while wasting hard disk space, a lot of manual labor is required;

[0005] 3. The video compression rates of hard disk video recorders from various manufacturers on the market are different, resulting in different video quality, which directly leads to blurred and distorted key photos captured
