3D Position Shift Correction for Virtual View Accuracy
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing techniques for generating virtual point-of-view images from multiple captured images struggle with maintaining accuracy due to changes in the state of image capturing apparatuses, such as shake or lens position changes, which affect the quality of the generated image content.
Innovation Solution
An information processing apparatus comprising a first acquisition unit for capturing images, a second acquisition unit for acquiring image capturing information, and a correction unit that corrects shifts between three-dimensional positions identified from feature points across multiple images and corresponding image capturing information, ensuring accurate image generation despite changes in the image capturing apparatuses.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If multiple image capturing apparatuses are used to generate virtual point-of-view images, then the quality and variety of image content is improved, but the accuracy of generated shape data decreases due to changes in apparatus state (shake, lens position changes)
Solution Approach 1:
The patent implements feedback by detecting the state of image capturing apparatuses (shake, lens position changes) and using this information to correct shifts in three-dimensional positions. The correction unit adjusts the reconstructed shape data based on detected apparatus state changes, creating a closed-loop system that maintains accuracy despite environmental disturbances.
Solution Approach 2:
The patent changes parameters by dynamically adjusting the three-dimensional position calculations based on detected apparatus state. When shake or lens position changes are detected, the system modifies the position parameters of reconstructed objects to compensate for the apparatus movement, thereby maintaining measurement precision.
2Measurement precision
If image capturing apparatuses are fixed in position and orientation, then measurement precision is maintained, but adaptability to different capturing scenarios decreases
Solution Approach 1:
The patent applies dynamics by transitioning from static apparatus positioning to dynamic state detection and correction. The system continuously monitors apparatus state (shake, lens position) and dynamically adjusts three-dimensional position calculations, allowing the system to adapt to different capturing scenarios while maintaining precision through real-time compensation.
3Measurement precision
If correction processing is applied to maintain accuracy, then shape data accuracy is improved, but device complexity increases due to additional correction units and processing steps
Solution Approach 1:
The patent introduces an intermediary correction unit that acts as a mediator between the image capturing apparatuses and the shape data generation process. This correction unit processes the raw data, applies necessary adjustments based on detected apparatus state, and outputs corrected three-dimensional positions, thereby maintaining accuracy without requiring fundamental changes to the entire system architecture.

AI summary
An information processing apparatus for correcting a shift between a first three-dimensional position in an image capturing region that is identified based on a position of a first feature point on a first image and a second three-dimensional position in an image capturing region that is identified based on a position of a second feature point corresponding to the first feature point on a second image.
