Methods for Camera Calibration via Bundle Adjustment - A simplified explanation of the abstract
This abstract first appeared for US patent application 20240104778 titled 'Methods for Camera Calibration via Bundle Adjustment
Simplified Explanation
The patent application describes methods for performing camera calibration for outward-facing cameras on devices like head-mounted display devices. The process involves determining relative rotational parameters of the cameras using an optimization technique, such as a two-view bundle adjustment algorithm, and then analyzing these parameters statistically to provide updated calibration values. The calibration process does not rely on tracking points of interest over time but instead focuses on the convergence of rotational parameters determined for different moments in time.
- Using cameras with overlapping fields of view
- Determining relative rotational parameters through optimization techniques
- Statistical analysis for updating calibration values
- Calibration process based on convergence of rotational parameters over time

Original Abstract Submitted
methods for performing a camera calibration process for outward-facing cameras on devices such as head-mounted display devices are disclosed. using cameras with overlapping fields of view, relative rotational parameters of the cameras with respect to one another may be determined using an optimization technique such as a two-view bundle adjustment algorithm. a statistical analysis of the relative rotational parameters of the cameras, determined for a plurality of moments in time, may then be made to provide updated relative rotational parameters for recalibration of the cameras. a camera calibration process, such as those disclosed, may not depend on tracking points of interest over multiple moments in time, but rather on a convergence of the relative rotational parameters determined for respective moments in time.
