Member Data Documentation

final int HINT_MAX_SIMULTANEOUS_IMAGE_TARGETS = 0
static

How many image targets to detect and track at the same time.

This hint tells the tracker how many images shall be processed at most at the same time. E.g. if an app will never require tracking more than two targets, this value should be set to 2. Default is: 1.

final int HINT_MAX_SIMULTANEOUS_OBJECT_TARGETS = 1
static

How many object targets to detect and track at the same time.

This hint tells the tracker how many 3D objects shall be processed at most at the same time. E.g. if an app will never require tracking more than 1 target, this value should be set to 1. Default is: 1.

final int HINT_DELAYED_LOADING_OBJECT_DATASETS = 2
static

Force delayed loading for object target DataSet.

This hint tells the tracker to enable delayed loading of object target datasets upon first detection. Loading time of large object dataset will be reduced but the initial detection time of targets will increase. Please note that the hint should be set before loading any object target dataset to be effective. To enable delayed loading set the hint value to 1. To disable delayed loading set the hint value to 0. Default is: 0.

final int HINT_ASYNC_FETCH_OF_LATEST_CALIBRATION = 3
static

Asynchronously fetch the latest device calibration profile.

This hint enables asynchronous fetching of the latest device calibration profile from the cloud, which does not block Vuforia's initialization until the calibration profile is successfully acquired. Skipping the blocking attempt to get the latest profile can cause the SDK to run in a non-optimized mode on the first run. By default, acquiring of the latest device calibration profile may block Vuforia's initialization for up to a maximum timeout of 10 seconds or until a new profile is successfully acquired from the cloud. Please note that the hint should be set before Vuforia's initialization to be effective. To enable asynchronous fetching set the hint value to 1. To disable asynchronous fetching set the hint value to 0. Default is: 0.

final int HINT_MODEL_TARGET_RECO_WHILE_EXTENDED_TRACKED = 4
static

Turn on recognition engine for an Advanced (360) Model Target dataset while extended tracking a model.

This hint enables the recognition engine when extended tracking an existing target. It needs to be set after the ObjectTracker has been initialized. Valid values for the hint are 0 or 1. When set to 0, the recognition engine is stopped for Advanced (360) datasets after a model target has been found and is never turned on again automatically. The dataset needs to be deactivated and activated, or the tracker stopped and started, in order to turn on recognition again. When set to 1, recognition is turned on as soon as an existing target is only extended tracked. If the recognition engine finds a new target in the image frame, tracking will be switched to the newly identified target, resulting in tracking loss of the prior model target Default is: 1

final int HINT_MODEL_TARGET_MODE = 5
static

Set Model Target tracking mode.

This hint modifies the internal Model Target tracking parameters to optimize the tracking quality and robustness for different target types.

Note: The hint can only be set when the ObjectTracker is stopped.

Valid values for the hint can be found in MODEL_TARGET_MODE. Note: to use this flag with setHint() method you need to static cast the value to an int Default is: MODEL_TARGET_MODE::MODEL_TARGET_MODE_DEFAULT
