Embodiment 1

[0038] Such as figure 1 As shown, it is a schematic flow chart of the video surveillance method described in Embodiment 1 of the present invention, and the video surveillance method may include the following steps:

[0039] Step 101: The multimedia processor receives the ultra-high-definition video image sent by the video acquisition device.

[0040] Step 102: Compress the ultra-high-definition video image according to a preset compression ratio to obtain a compressed video image; and, according to the set video format requirements, encode the compressed video image to obtain a compressed video stream .

[0041] Wherein, in one embodiment, the compressed video image is, for example, a high-definition video image or a standard-definition video image, and the compressed video stream is a high-definition video stream and a standard-definition video stream, respectively.

[0042] Among them, in order to collect high-definition video images for monitoring, the video collection eq...

Embodiment 2

[0059] Based on the same inventive concept, the embodiment of the present invention also provides a video monitoring device, such as image 3 Shown is a schematic structural diagram of the device, including:

[0060] The receiving module 301 is used to receive the ultra-high-definition video image sent by the video acquisition device;

[0061] The compressed video stream processing module 302 is used to compress the ultra-high-definition video image according to a preset compression ratio to obtain a compressed video image; and, according to the set video format requirements, perform compression processing on the compressed video image Encoding to obtain a compressed video stream;

[0062] The interest video stream processing module 303 is configured to intercept the image of the target area from the ultra-high-definition video image according to the predetermined target area in the ultra-high-definition video image to form an interest image; and, according to the set video ...

Abstract

The invention discloses a video monitoring method and a video monitoring device. In the technical scheme provided by the invention, a multi-media processor receives a UHDV (ultra high definition video) and then carries out the following two aspects of operation: on one hand, the UHDV is compressed and coded into a low-resolution compressed video stream, the low-resolution compressed video stream is sent to a client; therefore, a user can monitor pictures in the UHDV by the compressed video stream, which helps the user to know the dynamic state of the whole monitoring scene; as the data volume of the compressed video stream is less than the data volume of the UHDV, so that the network traffic for transmission of video stream can be saved; on the other hand, a picture in an object region is intercepted from the pictures of the UHDV, the picture in the object region is coded into an ultra high definition video stream, the ultra high definition video stream is sent to the client, so that the user can conveniently monitor the video through viewing the ultra high definition video stream, thereby being beneficial to monitoring, moreover, the user can clearly see the details of the pictures in the object region, therefore, the monitoring efficiency can be improved.

Description

technical field [0001] The invention relates to the technical field of video processing, in particular to a video monitoring method and device. Background technique [0002] Video surveillance has become an important security measure to ensure financial, personal and information security. In the prior art, there are mainly two methods for video monitoring: [0003] The first method is: use high-definition image and video acquisition equipment to collect high-definition video images, and then play them on the client side to facilitate monitoring. However, this method plays the entire image content collected by the high-definition image video acquisition equipment. Even if the user is only interested in part of the entire image, the whole image is played, which makes the target area not clear. , The monitoring efficiency is low. [0004] The second method is: use ultra-high-definition image video acquisition equipment to collect ultra-high-definition video images, and use t...
