First Claim
1. A picture presentation method, comprising:
- 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,wherein the 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, comprises;
selecting a reference to-be-presented picture from the reconstruction picture set, a number of three-dimensional feature points included in the reference to-be-presented picture being greater than a number of three-dimensional feature points included in any other reconstruction picture in the reconstruction picture set; and
selecting a plurality of to-be-subsequently-presented pictures satisfying a first preset condition in sequence from the reconstruction picture set by using the reference to-be-presented picture, the first preset condition comprising;
a number of different three-dimensional feature points included in the to-be-subsequently-presented picture and a to-be-subsequently-presented picture previously selected is greater than a number of different three-dimensional feature points included in a reconstruction picture that is not selected as a to-be-subsequently-presented picture and the to-be-subsequently-presented picture previously selected.

Abstract
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.
