C Specification

The possible premade profiles for an XrMarkerDetectorML are specified by the XrMarkerDetectorProfileML enumeration:

// Provided by XR_ML_marker_understanding
typedef enum XrMarkerDetectorProfileML {
    XR_MARKER_DETECTOR_PROFILE_DEFAULT_ML = 0,
    XR_MARKER_DETECTOR_PROFILE_SPEED_ML = 1,
    XR_MARKER_DETECTOR_PROFILE_ACCURACY_ML = 2,
    XR_MARKER_DETECTOR_PROFILE_SMALL_TARGETS_ML = 3,
    XR_MARKER_DETECTOR_PROFILE_LARGE_FOV_ML = 4,
    XR_MARKER_DETECTOR_PROFILE_CUSTOM_ML = 5,
    XR_MARKER_DETECTOR_PROFILE_MAX_ENUM_ML = 0x7FFFFFFF
} XrMarkerDetectorProfileML;

Description

Enumerant Descriptions

  • XR_MARKER_DETECTOR_PROFILE_DEFAULT_ML — Tracker profile that covers standard use cases. If this does not suite the needs of the application try the other profiles listed below.

  • XR_MARKER_DETECTOR_PROFILE_SPEED_ML — Optimized for speed. Use this profile to reduce the compute load and increase detection/tracker speed. This can result in low accuracy poses.

  • XR_MARKER_DETECTOR_PROFILE_ACCURACY_ML — Optimized for accuracy. Use this profile to optimize for accurate marker poses. This can cause increased load on the compute.

  • XR_MARKER_DETECTOR_PROFILE_SMALL_TARGETS_ML — Optimized for small targets. Use this profile to optimize for markers that are small or for larger markers that need to be detected from afar.

  • XR_MARKER_DETECTOR_PROFILE_LARGE_FOV_ML — Optimized for FoV. Use this profile to be able to detect markers across a larger FoV. The marker tracker system will attempt to use multiple cameras to detect the markers.

  • XR_MARKER_DETECTOR_PROFILE_CUSTOM_ML — Custom Tracker Profile. The application can define a custom tracker profile. See XrMarkerDetectorCustomProfileInfoML for more details.
