MegaTracker Class¶

This type is an EasyAR Sense API in C#: MegaTracker . Some descriptions may not apply to Unity environment on this page.

This type is partially wrapped into Unity components: MegaTrackerFrameFilter . Members and instances of this type are not required to be used directly in most situations. Use this type by MegaTrackerFrameFilter.Tracker instead of creating new instances when a few unwrapped API is desired for use.

Description¶

Provides cloud based localization.

MegaTracker occupies 1 buffers of camera.

Methods¶

isAvailable¶

C#: public static bool isAvailable()

Check whether SparseSpatialMap is is available, always return true.

inputFrameSink¶

C#: public virtual InputFrameSink inputFrameSink()

Input port for input frame. For MegaTracker to work, the inputFrame must include camera parameters, timestamp and spatial information. See also InputFrameSink .

setInputFrameSourceType¶

C#: public virtual void setInputFrameSourceType( InputFrameSourceType type)

Sets source type of input frames.

accelerometerResultSink¶

C#: public virtual AccelerometerResultSink accelerometerResultSink()

Input port for accelerometer result. See also AccelerometerResultSink .

locationResultSink¶

C#: public virtual LocationResultSink locationResultSink()

Optional. Input port for location result. See also LocationResultSink .

proximityLocationResultSink¶

C#: public virtual ProximityLocationResultSink proximityLocationResultSink()

Optional. Input port for proximity location result. See also ProximityLocationResultSink .

bufferRequirement¶

C#: public virtual int bufferRequirement()

Camera buffers occupied in this component.

outputFrameSource¶

C#: public virtual OutputFrameSource outputFrameSource()

Output port for output frame. See also OutputFrameSource .

create¶

C#: public static MegaTracker create(string server, string apiKey, string apiSecret, string appId)

Creates an instance.

setRequestTimeParameters¶

C#: public virtual void setRequestTimeParameters(Optional<int> timeoutMilliseconds, int requestIntervalMilliseconds)

Sets request time parameters. timeoutMilliseconds is connection timeout. requestIntervalMilliseconds is the expected request interval, and the default value is 1000 and the minimum value is 300, with a longer value results a larger overall error.

setResultPoseType¶

C#: public virtual void setResultPoseType(bool enableLocalization, bool enableStabilization)

Sets type of result pose. enableLocalization and enableStabilization default to true.

setLocalizationCallback¶

C#: public virtual void setLocalizationCallback( CallbackScheduler callbackScheduler, Optional<Action< MegaTrackerLocalizationResponse >> callback)

Sets request delay. On every localization, the callback will be triggered.

start¶

C#: public virtual bool start()

Start MegaTracker.

stop¶

C#: public virtual void stop()

Stop MegaTracker. Call start() to resume running.

reset¶

C#: public virtual void reset()

Reset MegaTracker and clear all internal states.

close¶

C#: public virtual void close()

Close MegaTracker. MegaTracker can no longer be used.
