Abstract

The invention discloses a video monitoring method and apparatus based on virtual cameras, applied to a video monitoring system. The method comprises the following steps: receiving basic stream video data from the camera, and virtualizing a predetermined number of virtual cameras; receiving a code stream request from a video terminal, and allocating the virtual camera to the received code stream request to serve as a stream sending end of the video terminal; sending the basic stream video data to the stream sending end, packaging the basic stream video data of the stream sending end according to a code stream package mode corresponding to the code stream request, and sending the packaged basic stream video data to the corresponding video terminal. By adoption of the video monitoring method and apparatus disclosed by the invention, the shared use of the camera is achieved, thereby greatly reducing the deployment number of physical cameras and improving the monitoring utilization rate of the cameras, only a plurality of virtual cameras are configured to be compatible with different platforms, and the cameras only need to send encoded basic streams, so that the performance requirements for the cameras are greatly reduced, and the investment cost of the cameras is reduced.

Description

technical field

[0001] The invention belongs to the technical field of video monitoring, and in particular relates to a video monitoring method and device based on a virtual camera. Background technique

[0002] The video monitoring system is an important part of the security system, and it is widely used in the security monitoring of various places (such as workplaces, offices, entertainment places, homes, etc.). Under the existing technical conditions, a video monitoring system usually consists of a monitoring device end (ie, a camera) and a monitoring terminal (ie, a video terminal).

[0003] For the monitoring of the same scene, because the monitoring platforms (that is, video terminals) of departments at all levels are connected in different ways, the compatible protocols are different. Because in order for each video terminal to monitor normally, it is necessary to deploy a protocol compatible with the video terminal. A corresponding number of cameras is set to meet t...
