Augmented reality platforms that are based on camera mapping often have the capability to recognize user-specified images in the environment and provide tracking information for them. The Image Tracking API makes this feature available to WebXR applications. Since detecting and tracking these images happens locally on the device, this functionality can be implemented without providing raw camera images to the application.


Allows applications to detect the presence and location of a set of application-specified images or markers in the real-world environment. This is an alternative to the proposed WebXR Raw Camera Access API ( While applications could use that API for computer vision algorithms to do similar detection, that requires granting the application site access to raw camera images. The Image Tracking API works locally on the device and does not provide camera data to the application, it only reports data about the specific images for which tracking was requested.
