1、选择目标图

选择了一个与模型寒冰相关的图片

AIXI.jpg

2、上传图片到官网的数据库

3、查看该图片目标的识别星级

4、下载数据到本地

浏览器会下载.unitypackge的包，包名与你创建的数据集名字一样，导入unity即可。

5.在unity中选择自己的数据

6.控制模型的生成

创建脚本AR，附加在imagTagert,移除自身的，继承接口 ITrackableEventHandler

using System.Collections;
using System.Collections.Generic;
using UnityEngine;
using Vuforia;


public class AR : MonoBehaviour, ITrackableEventHandler
{


    protected TrackableBehaviour mTrackableBehaviour;  //声明可识别行为脚本

    public GameObject AIXIPrefab;//模型预制

    private GameObject aixi; //生成的模型


    protected virtual void Start()
    {
        mTrackableBehaviour = GetComponent<TrackableBehaviour>();
        if (mTrackableBehaviour)
            mTrackableBehaviour.RegisterTrackableEventHandler(this);
    }

    protected virtual void OnDestroy()
    {
        if (mTrackableBehaviour)
            mTrackableBehaviour.UnregisterTrackableEventHandler(this);
    }

 


    /// <summary>
    ///  状态的改变
    /// </summary>
    public void OnTrackableStateChanged(
        TrackableBehaviour.Status previousStatus,
        TrackableBehaviour.Status newStatus)
    {
        if (newStatus == TrackableBehaviour.Status.DETECTED ||
            newStatus == TrackableBehaviour.Status.TRACKED ||
            newStatus == TrackableBehaviour.Status.EXTENDED_TRACKED)
        {
            Debug.Log("Trackable " + mTrackableBehaviour.TrackableName + " found");
            OnTrackingFound();
        }
        else if (previousStatus == TrackableBehaviour.Status.TRACKED &&
                 newStatus == TrackableBehaviour.Status.NOT_FOUND)
        {
            Debug.Log("Trackable " + mTrackableBehaviour.TrackableName + " lost");
            OnTrackingLost();
        }
        else
        {
            OnTrackingLost();
        }
    }


    /// <summary>
    /// 识别到物体
    /// </summary>
    protected virtual void OnTrackingFound()
    {
        aixi = GameObject.Instantiate(AIXIPrefab);
        aixi.transform.position = this.transform.position;
        aixi.transform.SetParent(this.transform);

       
    }


    /// <summary>
    /// 丢失物体
    /// </summary>
    protected virtual void OnTrackingLost()
    {
        if (aixi != null)
        {
            Destroy(aixi);
        }
       

    }
}

主要接口方法：

OnTrackableStateChanged（TrackableBehaviour.Status previousStatus, TrackableBehaviour.Status newStatus）
