如图所示 后面的ui是摄像机的rawimage代码是：

using System.Collections;

using System.Collections.Generic;

using UnityEngine;

using UnityEngine.UI;



[RequireComponent(typeof(RawImage))]  //脚本挂在RawImage  

public class CameraDevice : MonoBehaviour

{

    private List<WebCamTexture> webCamTextures = new List<WebCamTexture>();

    private RawImage image;

    #region Unity Method

    // Called once before Start

    void Awake()

    {

        image = GetComponent<RawImage>();

    }



    // Use this for initialization

    IEnumerator Start()

    {
        //获取授权  
        yield return Application.RequestUserAuthorization(UserAuthorization.WebCam);
        if (Application.HasUserAuthorization(UserAuthorization.WebCam))
        {

            WebCamDevice[] devices = WebCamTexture.devices;
