Unity的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,
}
