TargetInstance Class¶

Description¶

TargetInstance是被tracker跟踪到的target。

TargetInstance包括被跟踪上的原始 Target 以及这个 Target 当前的状态和姿态。

Constructor¶

C: void easyar_TargetInstance__ctor(easyar_TargetInstance * * Return)¶

C++17: TargetInstance()¶

Traditional C++: TargetInstance()¶

Java: public TargetInstance()¶

Kotlin: constructor()¶

Objective-C: + (easyar_TargetInstance *) create¶

Swift: public convenience init()¶

C#: public TargetInstance()¶

status¶

返回当前被跟踪target的状态。通常你可以status是否等于 TargetStatus.Tracked 来判断当前target的状态。

C: easyar_TargetStatus easyar_TargetInstance_status(const easyar_TargetInstance * This)¶

C++17: TargetStatus status()¶

Traditional C++: TargetStatus status()¶

Java: public int status()¶

Kotlin: fun status(): Int¶

Objective-C: - (easyar_TargetStatus)status¶

Swift: public func status() -> TargetStatus¶

C#: public virtual TargetStatus status()¶

target¶

获取原始target。如果曾经被加载到tracker中，会返回与load进 tracker 相同的 Target 。

C: void easyar_TargetInstance_target(const easyar_TargetInstance * This, easyar_OptionalOfTarget * Return)¶

C++17: std::optional<std::shared_ptr<Target>> target()¶

Traditional C++: void target(Target * * Return)¶

Java: public @Nullable Target target()¶

Kotlin: fun target(): Target?¶

Objective-C: - (easyar_Target *)target¶

Swift: public func target() -> Target?¶

C#: public virtual Optional<Target> target()¶

pose¶

返回当前被跟踪的target相对于Camera的位姿。其中camera坐标系与target坐标系均为右手坐标系。Camera坐标系的原点为相机光心，x轴正方向为右，y轴正方向为上，z轴正方向为光线进入相机的方向。（其中的右和上，在移动设备上指设备自然方向的右和上。）数据的排列方式为row-major，与OpenGL的column-major相反。

C: easyar_Matrix44F easyar_TargetInstance_pose(const easyar_TargetInstance * This)¶

C++17: Matrix44F pose()¶

Traditional C++: Matrix44F pose()¶

Java: public @Nonnull Matrix44F pose()¶

Kotlin: fun pose(): Matrix44F¶

Objective-C: - (easyar_Matrix44F *)pose¶

Swift: public func pose() -> Matrix44F¶

C#: public virtual Matrix44F pose()¶
