Embodiment Construction

[0043] Embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0044] figure 1 A schematic diagram of a layered encoding and decoding technology adopted in the embodiment of the present invention is shown.

[0045] Layered video coding is to divide the video image into a base layer and multiple enhancement layers to create a video image. These video streams are respectively carried in different data packets on the network. The impact of the base layer packet loss and non-layerable The result of encoding is consistent, and the enhancement layer is based on the base layer instead of the previous frame image. Therefore, the loss of data packets in the enhancement layer will not cause the degradation of image quality, thereby greatly improving the anti-packet loss capability of the video.

Abstract

The present invention relates to a video monitoring system and a large-scale video scheduling method. The system includes a plurality of video acquisition devices, a video encoding device and a video display device; The video information is sent to the video encoding device; the video encoding device is used to perform layered encoding on the video information collected by the plurality of video acquisition devices, and obtain a plurality of encoded segments corresponding to each video acquisition device. Layer video information; the video encoding device is also used to send layered video information to the video display device after receiving the video request information; the video display device is used to convert the layered The video information is displayed in a three-dimensional geographic information system corresponding to the location identified by the video capture device. The invention improves the scale of decoding and displaying video of the video display device.

Description

technical field [0001] The invention relates to the field of three-dimensional geographic information, in particular to a video monitoring system and a large-scale video scheduling method. Background technique [0002] The field of computer vision involves the encoding and decoding of video and the transmission of data. Video codec refers to the compression or decompression of digital video. Scaled Video Coding (SVC) is a technology that can divide a video stream into multiple resolutions and frame rates. It is an extension of the H264 video coding standard used by most video conferencing equipment today. SVC can greatly improve bit error resilience and video quality, and does not have high requirements for bandwidth. SVC is widely used in video transmission and display, which can improve the transmission efficiency of video, thereby improving the overall effect of the surveillance video system. [0003] Traditional video surveillance is mainly two-dimensional, and multip...
