Stereo Camera Configuration for Virtual Set Parallax
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current stereo camera configurations struggle to ensure optimal parallax characteristics for 3D content projection, particularly in virtual and physical environments, leading to discomfort and visual issues for viewers due to inadequate adjustment of camera positions and distances.
Innovation Solution
A computer-implemented method and graphical user interface that allow users to configure stereo cameras by detecting relocation within a virtual set, updating three-dimensional views, and adjusting planes such as the convergence distance plane and infinity distance plane, ensuring that the interaxial distance and parallax characteristics align with human interocular distance for comfortable 3D viewing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If stereo cameras are configured with fixed interaxial distance, then device complexity is reduced, but viewer comfort deteriorates due to inadequate parallax adjustment
Solution Approach 1:
The patent implements dynamic camera configuration by allowing the interaxial distance to be adjusted based on detected manipulator relocation. The system transitions from fixed camera spacing to variable spacing that adapts to the virtual set configuration, enabling optimal parallax characteristics while maintaining computational simplicity through automated detection and calculation.
Solution Approach 2:
The system changes the interaxial distance parameter automatically based on the manipulator's new position in the virtual set. By calculating the required camera spacing from the manipulator relocation data, the system adjusts this critical parameter to ensure comfortable viewing without requiring manual configuration or complex user input.
2Manufacturing precision
If camera positions are manually adjusted, then manufacturing precision is improved, but productivity decreases due to time-consuming configuration
Solution Approach 1:
The system performs self-configuration by automatically detecting manipulator relocation and calculating the required camera positions. Instead of requiring manual adjustment or complex user guidance, the system serves itself by using the detected manipulator data to directly compute and apply the correct interaxial distance, achieving both precision and speed.
Solution Approach 2:
The patent replaces manual mechanical adjustment with automated computational calculation. By substituting the manual process with algorithmic calculation based on manipulator relocation data, the system achieves precise camera positioning instantaneously without human intervention or time-consuming physical adjustment.
3Ease of operation
If parallax is increased for depth effect, then visual experience is improved, but viewer comfort deteriorates due to excessive interocular distance violation
Solution Approach 1:
The system incorporates feedback by continuously monitoring manipulator relocation and using this information to adjust camera configuration in real-time. The detected manipulator position provides feedback that triggers automatic recalculation of interaxial distance, ensuring parallax remains within comfortable limits while maximizing depth effect for enhanced visual experience.
