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.

Panoramic image generating method and apparatus

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 (); extracting a moving target from at least two cuboid three-dimensional images (); performing image fusion processing on the panoramic video image and the moving target to form a panoramic video image incorporated with the moving target (). 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.

Method and device for fusing panoramic video images

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. The real-time performance for generating a panoramic video is improved, as no complicated image stitching algorithm is used. In addition, the cost for camera devices can be reduced, as there is no need for several cameras or an aerial camera.
