VR Camera Stitching Markers for Post-Processing Complexity
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Post-production editing of virtual reality (VR) captured content is challenging due to the complexity of stitching together images from multiple cameras, especially when stitching regions contain detailed or moving scenery, which requires significant expertise, time, and resources.
Innovation Solution
A virtual reality visual indicator apparatus that uses a visual indicator provider to transmit markers indicating stitching regions before image capture, allowing for the arrangement of less complex scenery in these areas, thereby simplifying the post-processing of VR images by reducing the complexity of stitching regions during image capture.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If multiple cameras are used to capture VR content, then the immersive experience is improved, but the complexity of post-production stitching increases
Solution Approach 1:
The patent applies preliminary action by projecting visual indicators (lasers) onto the scene before image capture to mark stitching regions. This allows the scene to be prepared in advance with clear boundaries indicated, so that during post-production, the stitching process can reference these pre-marked areas rather than having to analyze and determine stitching regions from complex captured imagery. The visual indicators are transmitted into the scene prior to capture and then removed during processing, effectively performing the stitching region identification step beforehand.
2Manufacturing precision
If detailed scenery is present in stitching regions, then the visual quality of the scene is improved, but the difficulty of stitching increases
Solution Approach 1:
The patent introduces an intermediary element - the visual indicator (laser projection) - that mediates between the detailed scenery and the stitching process. The laser indicators are projected onto the scene to mark the boundaries of stitching regions, serving as a reference layer that separates the complex visual content from the stitching task. This intermediary allows stitchers to identify exactly where stitching should occur without having to analyze the complex detailed scenery to determine appropriate stitching locations, thus reducing the difficulty of detecting and measuring stitching regions while preserving the detailed visual content.
3Measurement precision
If visual indicators are transmitted into the scene, then the stitching region identification is improved, but the scene complexity during capture increases
Solution Approach 1:
The patent applies periodic action by transmitting visual indicators into the scene only during specific phases: before image capture to mark stitching regions, and potentially during setup phases, but not continuously during the actual capture process. The indicators are transmitted periodically or intermittently based on operational needs, and then removed or deactivated during the critical capture phase to minimize scene complexity. This periodic transmission allows stitching region identification to be performed accurately when needed while keeping the scene relatively simple during image capture.
