Video See-Through Augmented Reality - A simplified explanation of the abstract
This abstract first appeared for US patent application 20240046575 titled 'Video See-Through Augmented Reality
Simplified Explanation
The abstract describes a method for calibrating a video see-through augmented reality (AR) system using stereo images and position data. The method involves capturing stereo images of a calibration object and obtaining position data for each camera at the time of capture. A 3D reconstruction of the calibration object is generated, and a registration process is performed using parameters of virtual cameras. Differences between the virtual images and a virtual rendering of the calibration object are determined and used to adjust the virtual-camera parameters or store them for the system.

Original Abstract Submitted
in one embodiment, a method includes capturing, using a pair of cameras of a video see-through ar system, stereo images of a predetermined calibration object having a predetermined pose and obtaining, by a position sensor, position data for each of the pair of cameras at a time when the stereo images are captured. the method further includes generating a 3d reconstruction of the calibration object. the method further includes performing a registration process by generating, using parameters of each of a pair of stereo virtual cameras, stereo virtual views that include the predetermined calibration object and determining, for each of the stereo virtual views, one or more differences between the predetermined calibration object in the virtual images and a virtual rendering of the calibration object, and then using those differences to either adjust the virtual-camera parameters and repeat the registration process or to store the parameters for the system.
