Title: METHOD AND DEVICE FOR THREE-DIMENSIONAL PRESENTATION OF SURVEILLANCE VIDEO
Abstract:
Embodiments of the present application are applicable in an electronic device. Provided are a method and device for three-dimensional presentation of a surveillance video. The method comprises: acquiring a surveillance video and a three-dimensional background model and video grid information preconfigured and corresponding to a scenario in which the surveillance video is captured, where the video grid information comprises the size of each image area in a video image of the surveillance video and the area coordinates of each image area in the three-dimensional background model; partitioning the video image in the surveillance video into multiple image areas of corresponding sizes on the basis of the video grid information, and adjusting the image areas on the basis of the area coordinates of each image area in the three-dimensional background model that the video grid information comprises; and superimposing the adjusted image areas over areas of corresponding coordinates in the three-dimensional background model. The embodiments of the present application implement deep integration of the surveillance video with the three-dimensional background model, thus increasing three-dimensional presentation effects of the surveillance video.
