Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods lack the capability to effectively project a source image onto a geometrically changing surface, as they do not provide a suitable means to identify and adjust the number and location of source and target pixels in real-time.
Innovation Solution
A device comprising a viewable surface image sampler, comparator, and image modification unit that generates and modifies source image frames to match the geometrically changing surface by identifying and comparing surface and source image pixels, determining target pixels, and reconfiguring the image for accurate projection.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If a source image is projected onto a geometrically changing surface without real-time pixel identification and adjustment, then the projection process is simple, but the image does not fit the changing surface geometry accurately
Solution Approach 1:
The system captures an image of the viewable surface in advance to establish a reference geometry. This preliminary action allows the system to pre-determine the relationship between surface coordinates and projector pixel coordinates, enabling accurate projection without real-time complex calculations during the actual projection process.
Solution Approach 2:
The patent introduces a viewable surface image sampler and comparator as intermediary components that mediate between the source image and the projector. These intermediaries capture surface geometry, compare it with stored reference data, and determine the appropriate pixel mapping, thereby achieving accurate image fitting without requiring direct real-time complex geometric calculations.
2Reliability
If the number and location of pixels are adjusted in real-time to match a changing surface, then the image fits the surface accurately, but the processing time and computational load increase
Solution Approach 1:
The system performs preliminary capture and storage of the viewable surface image to establish a reference geometry before projection. This allows the pixel mapping relationships to be predetermined, reducing the computational burden and processing time during actual projection while maintaining accuracy on dynamically changing surfaces.
Solution Approach 2:
The system dynamically adjusts the pixel mapping based on the captured surface geometry. By using the viewable surface image sampler to detect actual surface positions and comparing them with reference data, the system adaptively determines the number and location of target pixels, enabling accurate projection on changing surfaces without requiring exhaustive real-time calculations for every possible surface configuration.
3Adaptability or versatility
If a fixed pixel grid is used for projection, then the projection system is simple to implement, but the image cannot adapt to geometrically changing surfaces
Solution Approach 1:
The patent implements a dynamic pixel mapping system that adapts to changing surface geometries. The viewable surface image sampler captures the actual surface configuration, and the comparator dynamically determines the appropriate pixel mapping by comparing captured data with reference geometry. This allows the system to adapt to various surface shapes and movements while maintaining a relatively simple overall architecture.
Solution Approach 2:
The system uses the viewable surface image sampler to automatically detect and capture the actual surface geometry without external intervention. The comparator then autonomously compares this captured data with stored reference information and self-determines the appropriate pixel mapping, enabling the system to adapt to changing surfaces autonomously without requiring complex external control mechanisms.

AI summary
A device for modifying source image frames to create modified image frames and for projecting the modified image frames onto a geometrically changing viewable surface is presented. The device may include a viewable surface image sampler for outputting surface image frames each including surface image pixels that reflect the geometrically changing viewable surface and a comparator in circuit with the surface image sampler. The comparator may be configured for identifying a number and a location of the surface image pixels of one or more of the surface image frames and for identifying a number and a location of source image pixels in one or more of the source image frames. The comparator may be further configured to thereafter compare the number and the location of the surface image pixels with the number and the location of the source image pixels to determine a number and a location of target pixels. An image modification device may be interconnected with the comparator and configured to receive the target pixels and to reconfigure the one or more source image frames to one or more modified image frames that are reconfigured to fit the target pixels and thereby fit the geometrically changing viewable surface. At least one projector may be configured to project the one or more modified image frames onto the geometrically changing viewable surface.
