Face feature video device

Abstract

The invention discloses a face feature video device, comprising digital signal processing chip, and video I / O unit connected with digital signal processor through the video interface of the digital signal processing chip, where the video I / O unit comprises two video decoding chips and two video input interfaces and also comprises a loop circuit, and on the condition that the face feature video device is power-off, the monitoring system can still normally work. And the invention can obtain video information of monitored environment and clear video information of specific monitored objects at the same time, beneficial to accuracy and practicality of the monitoring system.

Description

technical field [0001] The invention relates to a video device, in particular to a facial feature video device. Background technique [0002] The current digital surveillance system stores the original video stream on the hard disk after being compressed by a video compression board or an embedded digital video recorder (Digital Video Recorder, DVR for short). When it is necessary to view the video, it can be retrieved and played back through the monitoring software to obtain useful information. Due to the limitations of storage conditions, the current video compression algorithms all use lossy compression methods, so the video stream generated after the original video stream passes through the video codec will have a higher picture quality than the original video stream. Loss. If the face on the video screen is small, it will be found that the face will be very blurred during playback, and the facial features of the face can hardly be seen clearly.

However, this count is only instantaneous. When the customer completes the business and the salesperson uses the money counter again, the excess points of the previous customer will disappear.

Since the existing digital monitoring system cannot clearly record the facial features of the monitored object, and cannot monitor and save the video signals of the monitored object and the environment at the same time, especially for some backlit scenes, the problem of unclear images is more prominent

Therefore, it is difficult to serve as direct and effective evidence, which has caused many difficulties for the public security organs or security departments to carry out investigations and follow-up work, and will cause some cases to be unsolved or finalized, causing great damage to the property of the country and the people. loss
