See-Through Image Alignment for Viewing-Angle Distortion
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing see-through image display systems cause incongruity between visual and somatosensory information due to positional and color shifts when capturing three-dimensional objects, especially when the photographer's viewing angle differs from the camera's field of view, and require distance measurement for homograph transformation.
Innovation Solution
A see-through image display system that includes an image capturing device for the photographer, multiple image capturing devices for the object, a viewing angle detection portion, and an image connection portion to connect and perform homograph transformation on captured images without measuring the distance, using facial recognition and optical parameter detection to align viewing angles.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If homograph transformation is used for see-through image display, then the display can be generated, but distortion occurs to images of three-dimensional objects with depth
Solution Approach 1:
The patent changes the transformation parameters by using detected viewing angle and positional information to dynamically adjust the homograph transformation parameters. This allows the transformation to adapt to different viewing conditions and object positions, reducing distortion while maintaining ease of generation.
Solution Approach 2:
The system implements feedback by detecting the photographer's viewing angle and the relative position between camera and object, then using this information to adjust the homograph transformation parameters. This closed-loop approach compensates for distortion caused by depth and viewing angle variations.
2Ease of manufacture
If distance measurement is performed for homograph transformation, then transformation can be achieved, but device complexity increases
Solution Approach 1:
The patent uses an intermediary approach by leveraging the camera's existing positional information and detected viewing angle as intermediate parameters. Instead of directly measuring distance to the object, the system uses these intermediary measurements to calculate the necessary transformation parameters, avoiding complex distance measurement devices.
Solution Approach 2:
The system captures the photographer's viewing angle by imaging their face and detecting eye position, creating a copy of the viewing information. This copied information is then used to determine transformation parameters without requiring direct distance measurement to the target object.
3Adaptability or versatility
If the photographer's viewing angle differs from the camera's field of view, then capturing flexibility is improved, but positional deviation and color shift occur
Solution Approach 1:
The system dynamically adjusts the see-through image generation based on the detected viewing angle and relative position. By making the transformation parameters dynamic rather than fixed, the system can accommodate different viewing angles and camera positions while maintaining alignment accuracy and reducing positional deviation.
4Ease of manufacture
If the display range of screen is narrower than the field of view, then see-through image can be displayed, but user concentration is required and search time increases
Solution Approach 1:
The patent addresses the narrow display range issue by performing homograph transformation that maps the wide field of view onto the narrower display screen while preserving spatial relationships. This dimensional transformation allows the see-through image to be displayed in the limited screen area without requiring users to search extensively, as the transformed image maintains proper alignment and context.
