US 2019/0058875 A1 · Three-Dimensional Surveillance System, and Rapid Deployment Method for Same

Abstract

The present application relates to a video surveillance technology, and discloses a 3D monitoring system and a rapid deployment method for the same. In the present application, two corresponding point sets are obtained by means of an input device respectively in a virtual scene and in a monitoring video, so as to obtain a mapping between the virtual scene and the monitoring video; and a video mesh, to be superimposed and displayed on the virtual scene, is generated based on this mapping. Thus, a 3D monitoring system can be rapidly deployed without calibrations of intrinsic and extrinsic parameters of a camera, and requirements on accuracy in matching between a 3D monitoring scene and an actual monitored site are decreased, greatly reducing the difficulty in system deployment while ensuring the effect of superimposing a monitoring video on a virtual scene.

Dependent claims

A rapid deployment method for a 3D monitoring system, comprising:

displaying a virtual scene and a monitoring video of a monitored site;
obtaining, through an input device, N points selected in the virtual scene as a first point set, and obtaining, through an input device, N points selected in the monitoring video as a second point set, wherein N is greater than 2, and there is a one-to-one correspondence between points in the first point set and points in the second point set respectively, so that a first mapping between the virtual scene and the monitoring video is formed;
generating a first video mesh according to the first mapping, wherein a texture of the first video mesh is at least a part of the monitoring video;
and
superimposing and displaying the first video mesh on the virtual scene.

A 3D monitoring system, comprising:

a processor;
and
a memory, coupled to the processor and having stored thereon program instructions that, upon execution by the processor, cause the system to perform a method comprising:
displaying a virtual scene and a monitoring video of a monitored site;
obtaining, through an input device, N points selected in the virtual scene as a first point set, and obtaining, through an input device, N points selected in the monitoring video as a second point set, wherein N is greater than 2, and there is a one-to-one correspondence between points in the first point set and points in the second point set respectively, so that a first mapping between the virtual scene and the monitoring video is formed;
generating a first video mesh according to the first mapping, wherein a texture of the first video mesh is at least a part of the monitoring video;
and
superimposing and displaying the first video mesh on the virtual scene.
