Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing image processing methods fail to effectively present multiple user-shared pictures of the same scene in a way that enhances spatial continuity and richness of content, leading to a monotonous user experience.
Innovation Solution
A method and apparatus that acquire pictures of the same scene, determine their presentation order based on association relationships, and insert transition pictures to ensure smooth transitions, reconstructing a three-dimensional structure using SIFT keypoints and camera parameters to select and present pictures that cover the scene from multiple angles.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If pictures having the same scene are placed together randomly, then the presentation process is simple, but the scene presented is monotonous and cannot reflect the characteristics of the scene
Solution Approach 1:
The patent changes the parameter of picture arrangement from random to ordered based on spatial coordinates. By extracting coordinates from picture metadata and sorting pictures according to their spatial positions (longitude and latitude), the system transforms the presentation from a simple random sequence to a spatially-organized sequence that reflects the actual scene layout, thereby preserving scene characteristics without significantly increasing system complexity.
Solution Approach 2:
The patent introduces a spatial dimension to the picture presentation by using geographic coordinates (longitude and latitude) as the basis for arrangement. Instead of presenting pictures in a one-dimensional random sequence, the system maps pictures to their two-dimensional spatial positions in the scene, creating a presentation that reflects the actual spatial relationships and characteristics of the scene.
2Loss of information
If pictures are arranged in spatial order, then the spatial continuity of the scene is improved, but the transition between pictures becomes abrupt
Solution Approach 1:
The patent introduces transition pictures as intermediary elements between adjacent pictures in the spatial sequence. These transition pictures are generated by blending or interpolating between neighboring pictures based on their spatial coordinates, creating a smooth visual transition that bridges the gap between discrete pictures and maintains the continuity of the scene presentation.
3Ease of operation
If transition pictures are inserted between pictures, then the transition smoothness is improved, but the presentation time increases
Solution Approach 1:
The patent applies transition pictures selectively rather than universally. Transition pictures are inserted only between certain adjacent pictures in the spatial sequence, specifically where the spatial distance or visual difference between pictures is significant. This partial application of transitions provides smoothness where needed while avoiding unnecessary delays in sections where pictures are already visually similar or closely spaced.

AI summary
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.
