Focal length compensated augmented reality.

Abstract

The present disclosure is directed to presenting a more realistic augmented reality view on a video see-through display of a device by configuring the device such that the displayed image of the real world substantially matches what would be perceived by the user if the display were not present. This may be implemented by determining one or more of: a distance from the user's eyes to the display of the device, and an angular offset between the optical axis of a rear camera of the device and the user's visual field, and using the determined distance and/or angular offset to adjust the image that is displayed to the user. The image that is displayed to the user may be adjusted by optically or digitally zooming the rear camera of the device. It may also be adjusted by tilting the rear camera or by digitally translating the displayed video feed.

Background

TECHNICAL FIELD

The present disclosure relates generally to augmented reality technology.DESCRIPTION OF THE RELATED ART

Being immersed in augmented reality using a handheld mobile device or other augmented reality capable device, may be an engaging and unique experience.BRIEF SUMMARY OF THE DISCLOSURE

Techniques described herein are directed to presenting a more realistic augmented reality view on a video see-through display of a device by configuring the device such that the displayed image of the real world substantially matches what would be perceived by the user if the display were not present.

In one embodiment, a method includes: capturing and displaying a video feed of a real-world environment using a rear-facing camera of an augmented reality (AR) device of a user; determining a distance from a facial point of the user to a display of the AR device; based on at least the determined distance, digitally or optically zooming the video feed of the real-world environment; and after zooming the video feed, rendering an augmented reality object overlaid over the video feed. In implementations, the augmented reality device may be a handheld video see-through augmented reality device such as a smartphone or tablet.

In implementations, based on at least the determined distance, the rear-facing camera is optically zoomed by translating a zoom lens of the rear-facing camera. Alternatively, based on at least the determined distance, the displayed vide

Claims

1. A method, comprising: capturing and displaying a video feed of a real-world environment using a rear-facing camera of an augmented reality (AR) device of a user; determining a distance from a facial point of the user to a display of the AR device; based on at least the determined distance, digitally or optically zooming the video feed of the real-world environment; and after zooming the video feed, rendering an augmented reality object overlaid over the video feed. 11. A device, comprising: a display; a rear-facing camera; a processor; and a non-transitory computer-readable medium having instructions stored thereon that, when executed by the processor causes the device to: capture and display a video feed of a real-world environment using the rear-facing camera; determining a distance from a facial point of a user of the device to the display; based on at least the determined distance, digitally or optically zoom the video feed of the real-world environment; and after zooming the video feed, render an augmented reality object overlaid over the video feed. 21. A method, comprising: capturing and displaying a video feed of a real-world environment using a rear-facing camera of an augmented reality (AR) device of a user; determining a position of the user's eyes relative to a display of the AR device; based on the determined position of the user's eyes, determining an angular offset between an optical axis of the rear-facing camera and a visual field of the user; based on at least the determined angular offset, tilting the rear-facing camera or digitally translating the displayed video feed to match the displayed video feed to an image of the real-world environment that would be perceived by the user without the presence of the display; and after tilting the rear-facing camera or digitally translating the video feed, rendering an augmented reality object overlaid over the video feed.
