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.

Method and apparatus for generating indoor panoramic video

A method and a device for adjusting a 3D model are disclosed. The method includes: fusing a 2D video and a 3D model of a target monitored area to generate a mesh model (S); determining whether each set plane in the mesh model is even based on the location of a respective reference plane in the 3D model (S); for each set plane that is uneven, referred to as a target set plane, selecting an uneven point in the target set plane as a mark point (S), and generating a virtual plane based on the mark point and the reference plane corresponding to the target set plane (S); and adding the virtual plane to the 3D model, and for the 2D video, saving the 3D model in which the virtual plane is added (S). With the embodiments of the present application, operations for the uneven planes improve the effect of the fusion of a video and a 3D model. There is no need to modify a 3D scene model, which reduces the labor cost and time cost of modifying the 3D scene model.
