Google Cardboard 中的实时摄像头馈送

Question

我想在Google Cardboard应用程序中显示实时相机提要。基本上说 - 我只是想看看我的相机在纸板应用程序中看到的内容。你能告诉我如何实现它吗？我迷失在 Unity 中。

Answer 1

我认为您想要 Unity 的立体视图，它非常简单 尝试使用此代码从相机获取实时馈送，并按照以下步骤在纸板应用程序中制作您的应用程序。

/***** script for getting live feed from camera *****/
using System.Collections;
using System.Collections.Generic;
using UnityEngine;
using UnityEngine.UI;
public class CamScript : MonoBehaviour {
    private bool camAvilable ;
    private WebCamTexture webcam;
    private Texture2D defaultbackground;
    private Texture2D output;
    public RawImage background;
    public RawImage imageToDisplay;
    public AspectRatioFitter fit;
    private Color[] data;
    void IntialCam(){
        defaultbackground = background.texture;
        WebCamDevice[] cam_devices = WebCamTexture.devices;
        if(cam_devices.Length == 0){
            Debug.Log ("No Camera");
            camAvilable = false;
            return;
        }
        webcam = new WebCamTexture (cam_devices [0].name, 320, 400, 60);
        if (webcam == null) {
            Debug.Log ("Unable to detect camera");
            return;
        }
        webcam.Play ();
        background.texture = webcam;
        imageToDisplay.texture = output;
        camAvilable = true;
    }
    void GetFeed(){
        if(!camAvilable){
            return;
        }
        float ratio = (float)webcam.width / (float)webcam.height;
        fit.aspectRatio = ratio;
        float scaleY = webcam.videoVerticallyMirrored ? -1f : 1f;
        background.rectTransform.localScale = new Vector3 (1f, scaleY, 1f);
        int orinat = -webcam.videoRotationAngle;
        background.rectTransform.localEulerAngles = new Vector3 (0,0,orinat);
    }
    void Start () {
        IntialCam ();
        output = new Texture2D (320,400);
        GetComponent<Renderer> ().material.mainTexture = output; 
        data = new Color[webcam.width * webcam.height];
    }
    // Update is called once per frame
    void Update () {
        GetFeed ();
        webcam.GetPixels(data);
        output.SetPixels(data);
        output.Apply();
    }
}

现在要使其成为纸板应用程序，您只需要转到Unity 播放器设置>>其他设置>>选中虚拟现实复选框>>然后在虚拟现实 SDK 中选择纸板。

就是这样，现在只需构建它，您就会得到结果。
