Abstract: The present application discloses a method and apparatus for generating a panoramic image. A cuboid three-dimensional image of each local space is determined according to an original two-dimensional image of each local space in the overall space and a preset cuboid model corresponding to each local space, and then a three-dimensional panoramic image of the overall space is generated according to all determined cuboid three-dimensional images. Since the three-dimensional panoramic image of the overall space is generated according to the cuboid three-dimensional images of all local spaces, the overall space may be visually viewed at a three-dimensional angle of view to achieve the three-dimensional real-scene effect.

Abstract: Provided are a method and apparatus for fusion of a panoramic video to solve a problem that a panoramic video image formed by stitching is incomplete. The method includes: acquiring a panoramic video image (21); extracting a moving target from at least two cuboid three-dimensional images (22); performing image fusion processing on the panoramic video image and the moving target to form a panoramic video image incorporated with the moving target (23). Thereby, problems such as overlapping and disappearance of a moving target, in whole or in part, in a panoramic video image generated by adopting a cuboid three-dimensional model are solved, thereby ensuring the completeness of a panoramic video image and improving the quality of the panoramic video image.

Abstract: Embodiments of the present application disclose a method and apparatus for generating an indoor panoramic video. For each of frames of the fish-eye video, coordinates of each of pixels of this frame in an image coordinate system are converted into coordinates in a spherical coordinate system to obtain a spherical coordinate system-based hemispherical fish-eye image. The frustum parameters of each of the N texture images of N viewing angles for the hemispherical fish-eye image are determined according to a shape of a preset living room. Based on the frustum parameters of each of the N texture images of N viewing angles, the N texture images of N viewing angles for the hemispherical fish-eye image are obtained. The N texture images of N viewing angles are rendered onto the N faces inside the preset living room, to generate the panoramic video image corresponding to the frame. As such, in the embodiment of the present application, a panoramic video image having a stereoscopic effect can be generated.

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.
