Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing systems fail to correctly align the positions of images captured by lens units with two optical systems, leading to reversed positional relationships between the optical systems and the images, which affects the appropriate display of stereoscopic content.
Innovation Solution
A system and method for aligning the positions of images captured by a lens unit with two optical systems, using lens-specific metadata to adjust the position and orientation of left and right images, and applying equidistant cylinder transformation to correct the positional inversion.

Engineering Contradiction Analysis
1Manufacturing precision
If images are displayed using conventional methods without correction, then the display process is simple, but the positional relationship between the two images and the two optical systems becomes reversed
Solution Approach 1:
The patent applies preliminary action by performing position correction processing on the captured images before display. The system reads lens information metadata, determines the relative positions of the two optical systems, and pre-adjusts the image positions to match the correct spatial relationship. This ensures that when images are displayed, their positional relationships accurately reflect the actual optical system configuration, resolving the reversal issue without requiring hardware modifications.
Solution Approach 2:
The patent uses lens information metadata as an intermediary element to bridge the gap between the optical system configuration and image display. This metadata contains information about the relative positions of the two optical systems, which serves as a reference for the position correction processing. By using this intermediary data, the system can automatically determine the correct positional relationship and apply appropriate corrections, eliminating the need for complex manual calibration or additional hardware sensors.
2Manufacturing precision
If lens-specific metadata is used to adjust image positions, then positional alignment accuracy improves, but processing time increases
Solution Approach 1:
The patent performs position correction processing immediately after image capture, using the lens information metadata that is already embedded in the captured data. By reading and processing this pre-existing metadata, the system determines the relative positions of optical systems and applies corrections in a single processing step, rather than requiring multiple iterative adjustments or time-consuming calibration procedures.
Solution Approach 2:
The system uses self-service by automatically reading and utilizing the lens information metadata that is already present in the captured image data. The metadata contains the necessary information about optical system configurations, and the system autonomously processes this information to perform position corrections without requiring external intervention or additional time-consuming measurements. This self-contained approach minimizes processing time while maintaining high alignment accuracy.
