Panoramic Camera Orientation Maintenance via Magnetometer Remapping
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Panoramic camera devices experience image distortion when moved from their initial orientation, particularly in non-cylindrical configurations, as they fail to account for changes in camera orientation relative to the table, leading to uneven resolution and distorted facial images.
Innovation Solution
The implementation of a panoramic camera device with a processor, memory, and modules for image stitching and warping, along with a magnetometer and orientation initialization unit, which detects and corrects for camera rotations by applying remapping and warping functions to maintain consistent image orientation and resolution across the panoramic image.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the panoramic camera is moved to different positions or orientations, then the camera can capture different views or perspectives, but the image becomes distorted and resolution becomes uneven
Solution Approach 1:
The system dynamically adjusts the remapping function based on the camera's current orientation relative to the table. The processor determines the camera's rotational status and modifies the remapping parameters accordingly, allowing the system to adapt to different camera positions while maintaining consistent image quality and orientation.
Solution Approach 2:
The system changes the remapping function parameters according to the camera's orientation. When the camera rotates or changes position, the processor updates the remapping parameters to compensate for the positional change, thereby maintaining consistent resolution and preventing image distortion across different viewing angles.
2Ease of operation
If the panoramic camera is moved after adjustments are made, then the camera can reposition itself, but the previous adjustments are rendered incorrect and the image becomes distorted
Solution Approach 1:
The system uses feedback from the magnetometer to detect the camera's current orientation and feeds this information back to the processor. The processor then adjusts the remapping function based on this feedback, ensuring that image orientation remains accurate even after the camera has been repositioned.
Solution Approach 2:
The remapping function is made dynamic rather than static. It automatically adapts to the camera's current position and orientation, allowing the system to maintain reliable image orientation accuracy while permitting easy camera repositioning without requiring manual realignment.
3Manufacturing precision
If a non-cylindrical panoramic image is generated, then the resolution can be optimized for specific viewing angles, but the image becomes distorted when the camera is rotated
Solution Approach 1:
The system changes the remapping parameters dynamically based on the camera's orientation. When the camera rotates, the processor updates the remapping function to compensate for the rotation, thereby maintaining stable image orientation while preserving the resolution optimization benefits of non-cylindrical panoramic images.

AI summary
Systems and methods for maintaining orientation of a non-cylindrical panorama is described wherein an initial magnetometer reading is obtained for a panoramic camera. If the panoramic camera is rotated from an initial position, a new magnetometer reading is obtained and a magnitude of rotation is determined. The magnitude of rotation is factored into an image stitching and warping process to create a panoramic image that maintains the initial orientation.
