ARKit和Vuforia-标记识别

您可以处理标记的识别(在Vuforia中称为图像目标) 创建脚本:

public class CustomTrackableEventHandler : MonoBehaviour,
                                           ITrackableEventHandler
{
    ...

    public void OnTrackableStateChanged(
                                    TrackableBehaviour.Status previousStatus,
                                    TrackableBehaviour.Status newStatus)
    {
        if (newStatus == TrackableBehaviour.Status.DETECTED ||
            newStatus == TrackableBehaviour.Status.TRACKED ||
            newStatus == TrackableBehaviour.Status.EXTENDED_TRACKED)
        {
            OnTrackingFound(); 
            // **** Your own logic here ****
        }
        else
        {
            OnTrackingLost();
        }
    }
}

问题2:为了在那里放置3D内容,我需要获得标记的位置,然后我想使用ARKit进行跟踪。

您可以添加一个空游戏对象作为标记(ImageTarget)的子对象,层次结构将是:

YourMarker(ImageTarget)
     |__EmptyPlaceHolder

识别标记后,您可以通过编程获得其位置:

var placeHolder = GameObject.Find("EmptyPlaceHolder");
if(placeHolder != null){
    Debug.Log(placeHolder.transform.position); // all the location, localPosition, quaternion etc will be available to you

}
