A scene reconstruction method, apparatus, terminal device, and storage medium. The method includes: acquiring a first image set matching a to-be-reconstructed scene (); extracting a characteristic region of an image in the first image set by using a characteristic extraction algorithm (); performing recognition on the characteristic region to obtain a scene characteristic region in the image (); and performing three-dimensional reconstruction on the to-be-reconstructed scene according to the scene characteristic region in the image, and rendering and generating the to-be-reconstructed scene (). Some useless and unstable characteristic regions are filtered off, and the three-dimensional reconstruction on the to-be-reconstructed scene is performed only according to the scene characteristic region associated with the to-be-reconstructed scene, thereby improving the efficiency and accuracy of reconstruction.

Method and apparatus for reconstructing scene, terminal device, and storage medium

The present application discloses a picture presentation method and apparatus. A specific implementation of the method includes: acquiring an original picture set encompassing a same scene; selecting, from the original picture set, a reconstruction picture set for reconstructing a three-dimensional structure of the scene, and reconstructing the three-dimensional structure of the scene by using reconstruction pictures in the reconstruction picture set, the three-dimensional structure of the scene comprising three-dimensional feature points; selecting a to-be-presented picture set from the reconstruction picture set, a number of the three-dimensional feature points included in the to-be-presented picture set being above a preset threshold; determining a presentation order of to-be-presented pictures in the to-be-presented picture set, and generating a picture presentation sequence based on the presentation order of the to-be-presented pictures; and presenting pictures in the picture presentation sequence continuously. By acquiring pictures encompassing a same scene, determining a presentation order of the pictures based on the association relationship between the pictures, and continuously presenting the pictures according to the presentation order, this implementation improves the spatial continuity of the scene in the pictures when the pictures are presented.
