TargetInstance Class¶
Description¶
TargetInstance是被tracker跟踪到的target。
Constructor¶
- C
void easyar_TargetInstance__ctor(easyar_TargetInstance * * Return)
- C++17
TargetInstance()
- C++03
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()
- C++03
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()
- C++03
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。
