Vuforia判断当识别追踪的对象

  

 方法一，如果有多个识别对象，在Update中循环识别对象数组，获取TrackableBehaviour组件

foreach (var item in trackObjects)
        {
            var mTrackableBehaviour = item.GetComponent<Vuforia.TrackableBehaviour>();
            if (mTrackableBehaviour != null && (int)mTrackableBehaviour.CurrentStatus>1)
            {
                if (mTrackableBehaviour.transform.name == "追踪物体的Name")
                    {  }
                Debug.Log("追踪的物体名字为："+mTrackableBehaviour.Trackable.Name);
                break;
            }
            else
            {
                //
            }
        }

方法二，直接把代码挂在识别对象上，判断该对象是否被识别

　　　　　　　var mTrackableBehaviour = GetComponent<Vuforia.TrackableBehaviour>();
            if (mTrackableBehaviour != null && (int)mTrackableBehaviour.CurrentStatus>1)
            {
                if (mTrackableBehaviour.transform.name == "追踪物体的Name")
                    {  }
                Debug.Log("追踪的物体名字为："+mTrackableBehaviour.Trackable.Name);
                break;
            }

识别对象状态枚举：

public enum Status
        {
            NOT_FOUND = -1,
            UNKNOWN = 0,
            UNDEFINED = 1,
            DETECTED = 2,
            TRACKED = 3,
            EXTENDED_TRACKED = 4,
        }
