XR_EXT_spatial_image_tracking creates asynchronous bases and associates each detection with the source image. See formats, IDs and portability precautions.
Direct answer
The OpenXR 1.1.63 ratified extension XR_EXT_spatial_image_tracking defines asynchronously created reference image banks and components that associate a detected image with the corresponding input bank and index. The runtime must support at least RGB and RGBA formats defined by the extension. The application still needs to provide distinct and appropriate images, physical dimensions when supported, handle asynchronous creation, and validate quantity and quality limits on each device.
Common bank organizes product references
Packaging, signs and markers can be grouped into a standardized structure. The returned index links the tracking to the item inserted in the database.
Asynchronous creation avoids blocking the experience
Preparing visual data can be costly. The flow with future requires loading state, timeout and recovery when the bank is not ready.
Duplicate image makes result ambiguous
The specification warns against repeated references between active banks. Catalog needs curation to prevent inconsistent indexes or multiple responses.
Supported format does not guarantee good detection
Contrast, texture, reflection, distance and lighting remain crucial. API portability does not standardize the camera or algorithm for each runtime.
Nexus Reading
A robust pipeline versions database, image, physical size and acceptance criteria. Before scaling, measure acquisition time, loss, false positives, and recovery on target devices.
FAQ
Is the extension ratified?
Yes. The OpenXR 1.1.63 registration marks XR_EXT_spatial_image_tracking revision 1 as ratified.
How many images does the bank need to have?
The framework requires at least one reference image.
Can I repeat the same image in several active banks?
The specification recommends avoiding duplicates because they can cause inconsistent discovery or indexes.
