3D Scene Model for Expert Photo Composition
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional photography systems fail to effectively capture the depth and geometry of a 3D scene, limiting amateur photographers' ability to achieve expert-level photo compositions, as they lack the capability to incorporate 3D geometry information and often result in photos lacking wide/short angle effects.
Innovation Solution
A photographic system comprising a photo composition unit that determines an extracted view from a 3D scene using multi-view image geometry techniques and a photo synthesizer that synthesizes an output photo according to this view, incorporating photographic composition rules and user settings to provide expert-like photo compositions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If conventional 2D photo cropping methods are used, then image processing is simple, but depth information and 3D geometry are lost
Solution Approach 1:
The patent transitions from 2D photo cropping to 3D scene understanding by building a three-dimensional scene model from multiple images. This allows the system to preserve depth information and geometric relationships by operating in 3D space rather than merely cropping 2D images, directly resolving the information loss problem while managing complexity through structured 3D reconstruction
2Manufacturing precision
If expert photographers manually compose photos, then photo composition quality is high, but time consumption and difficulty are increased
Solution Approach 1:
The system enables automated photo composition by allowing the 3D scene model and algorithm to automatically determine optimal viewing positions, angles, and camera settings according to composition rules. This self-service approach eliminates the need for amateur photographers to manually learn and apply complex composition techniques, delivering expert-level results without the time investment
Solution Approach 2:
The system performs preliminary 3D scene reconstruction and pre-calculates optimal photo compositions based on composition rules before actual photo capture. By preparing the 3D model and determining best viewing angles in advance, the system eliminates time-consuming manual composition adjustments during photo taking, directly reducing loss of time while maintaining high composition quality
3Adaptability or versatility
If amateur photographers use simple camera lenses, then device complexity is low, but optical zoom control and angle effects are limited
Solution Approach 1:
The patent replaces mechanical optical zoom controls with computational methods. Instead of requiring complex variable focal length lenses, the system uses 3D scene reconstruction and virtual camera positioning to achieve different viewing angles and zoom effects through software processing, thereby gaining versatility without increasing mechanical device complexity
Solution Approach 2:
The system achieves versatile viewing angles and zoom effects by operating in 3D space rather than relying on 2D lens adjustments. By reconstructing the scene in three dimensions and virtually positioning cameras at different locations and angles, the system provides expert-level optical control capabilities without requiring complex physical lens mechanisms
