Monocular Device Stereo Image Alignment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for viewing stereoscopic images are cumbersome for multiple viewers, as they often require wearing glasses or head-mounted displays, making it difficult for multiple people to simultaneously view both stereoscopic and non-stereoscopic images comfortably.
Innovation Solution
A method using a monocular device worn on one eye and a remote display viewed with the other eye, where the monocular device adjusts its image alignment based on the position of the remote display using a camera and processor to provide a stereoscopic image experience, allowing multiple viewers without monocular devices to see two-dimensional images.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If traditional stereoscopic viewing methods (head mounted displays, shutter glasses, polarized glasses) are used, then stereoscopic images can be viewed, but multiple viewers cannot simultaneously view both stereoscopic and non-stereoscopic images comfortably
Solution Approach 1:
The viewing system is segmented into two independent parts: a monocular device for one eye and a remote display for the other eye. This segmentation allows the monocular device to be removed or adjusted while still providing stereoscopic viewing, enabling multiple viewers to share the system without each needing their own complete setup.
Solution Approach 2:
A remote display acts as an intermediary between the monocular device and the viewer's other eye. This intermediary allows the system to function with fewer components per viewer, enabling multiple people to view images simultaneously - some with monocular devices and others without - while maintaining stereoscopic capability.
2Adaptability or versatility
If monocular devices are provided for each viewer, then stereoscopic viewing is enabled, but device complexity and cost increase
Solution Approach 1:
The remote display serves multiple functions: it displays images for viewers without monocular devices, and it receives images from the monocular device to complete the stereoscopic pair. This multi-functionality reduces the number of dedicated monocular devices needed, as the remote display can serve multiple viewers in different configurations.
Solution Approach 2:
Instead of providing each viewer with their own complete monocular display system, the system uses a single monocular device that can be shared. The remote display creates a virtual copy of the viewing experience for others, allowing them to view the same stereoscopic images without requiring identical hardware.
3Device complexity
If images are displayed on a single display device, then device simplicity is maintained, but alignment precision between stereo image pairs becomes difficult to achieve
Solution Approach 1:
The system uses a camera to capture the remote display and feeds this information back to the monocular device. This feedback loop enables the processor to determine the relative position and orientation of the remote display, allowing automatic adjustment of the monocular display alignment to maintain precise correspondence between the two images.
Solution Approach 2:
Instead of using complex mechanical alignment mechanisms, the system replaces physical adjustment with digital image processing. The processor uses camera feedback to calculate alignment transformations and digitally adjusts the images displayed on the monocular device, substituting mechanical precision with computational precision.

AI summary
A method for viewing of a three dimensional image of a scene with a monocular device on one eye for viewing a first two-dimensional image of the scene and providing a second display for viewing a second two-dimensional image of the scene in a stereo image pair with the other eye. Using a camera to provide an image of the second display to determine the position of the second display relative to the first display. Adjusting the alignment of the first two-dimensional image in correspondence to the determined position of the second display relative to the first display, whereby the viewer perceives a three dimensional image of the scene and one or more other viewers that are not wearing monocular devices can view the second display with both eyes so that they can perceive a two-dimensional image of the scene.
