Method and device for displaying monitoring video three-dimensionally

Abstract

The embodiment of the invention provides a method and device for displaying a monitoring video three-dimensionally. The method and the device are applied to an electronic device. The method comprises the steps of obtaining the monitoring video and a three-dimensional background model and video mesh information which are pre-configured and correspond to a collection scene of the monitoring video, wherein the video mesh information comprises sizes of image areas in video images of the monitoring video and area coordinates of the image areas in the three-dimensional background model; segmenting the video images in the monitoring video into a plurality of image areas of corresponding sizes according to the video mesh information and adjusting the image areas according to the area coordinates of the image areas in the three-dimensional background model contained in the video mesh information; and superposing the adjusted image areas to the corresponding coordinate areas in the three-dimensional background model. According to the embodiment of the invention, the monitoring video images and the three-dimensional background model can be deeply integrated and the three-dimensional displaying effect of the monitoring video can be improved.

Description

technical field [0001] The invention relates to the technical field of video monitoring, in particular to a method and device for three-dimensional display of monitoring video. Background technique [0002] With the development of video technology, the method of displaying video in three dimensions, that is, the method of processing and simulating two-dimensional video images into three-dimensional dynamic real scenes, has been more and more used. For example, in the field of video surveillance, by displaying the surveillance video collected by the video collection device in three dimensions, users can see the video images in the surveillance scene more intuitively. [0003] Existing methods for displaying surveillance video in 3D mainly focus on only three-dimensionalizing the surveillance scene, that is, constructing a corresponding 3D background model in advance for each surveillance scene. When displaying surveillance video, for the surveillance video collected for each...

[0004] However, in the above method, the monitoring video and the 3D background model are actually separated, and each frame of the monitoring video is completely displayed on the 3D background model. Therefore, the monitoring video image cannot be deeply fused with the 3D background model. The three-dimensional display effect of the video is not intuitive enough
