Unity调用摄像头并截图

首先界面是这样的,很简易,脚本上挂了三个按钮

直接上代码

using UnityEngine;
using UnityEngine.UI;public class WebCamera : MonoBehaviour
{WebCamTexture camTexture;private WebCamDevice[] devices;/// <summary>/// 摄像头设备名/// </summary>string deviceName;/// <summary>/// 摄像头显示状态/// </summary>bool cameraIsOpen;public Button openCamera, closeCamera, screenShot;private void Awake(){//初始化摄像头显示的图像的大小camTexture = new WebCamTexture(deviceName, 800, 600, 60);}private void Start(){cameraIsOpen = false;openCamera.onClick.AddListener(OpenWebCamDevice);closeCamera.onClick.AddListener(CloseWebCamDevice);screenShot.onClick.AddListener(() =>{// 将图像传给截图方法if (camTexture.isPlaying)GetComponent<ScreenShot>().SaveScreenShot(camTexture);});}//通过GUI绘制摄像头要显示的窗口private void OnGUI(){//首先根据摄像头展示的画面来判断摄像头是否存在if (cameraIsOpen && camTexture){//绘制画面(Screen.width / 2 - 150f, Screen.height / 2 - 290,这里是画面距离场景的高和宽的限制)//800, 600是和camTexture的画面一样大的绘制窗口GUI.DrawTexture(new Rect(0, 0, 800, 600), camTexture);}if (!cameraIsOpen && camTexture)//不显示画面(没写这个步骤之前有个坑){GUI.DrawTexture(new Rect(Screen.width / 2 - 150f, Screen.height / 2 - 290, 0, 0), camTexture);}}/// <summary>/// 打开摄像头/// </summary>void OpenWebCamDevice(){//用户授权if (Application.HasUserAuthorization(UserAuthorization.WebCam)){//显示画面的设备就是要打开的摄像头devices = WebCamTexture.devices;//获取到设备名称deviceName = devices[0].name;//开启摄像头camTexture.Play();cameraIsOpen = true;}}/// <summary>/// 关闭摄像头/// </summary>void CloseWebCamDevice(){if (cameraIsOpen == true && camTexture != null){cameraIsOpen = false;camTexture.Stop();}}
}

截图脚本

using System;
using System.IO;
using UnityEngine;public class ScreenShot : MonoBehaviour
{readonly string savePath = Application.streamingAssetsPath + "/my"; // 图片保存路径public void SaveScreenShot(Texture texture){Texture2D jietuTexture = TextureToTexture2D(texture);Save(jietuTexture);}/// <summary>/// 保存图片/// </summary>/// <param name="texture2D"></param>void Save(Texture2D texture2D){byte[] textureBytes = texture2D.EncodeToPNG();string filename = string.Format("IMG_{0}{1}{2}_{3}{4}{5}.jpg", DateTime.Now.Year, DateTime.Now.Month, DateTime.Now.Day, DateTime.Now.Hour, DateTime.Now.Minute, DateTime.Now.Second);if (!Directory.Exists(savePath)){Directory.CreateDirectory(savePath);}Debug.Log("保存路径=====" + savePath + "/" + filename);File.WriteAllBytes(savePath + "/" + filename, textureBytes);if (File.Exists(savePath + "/" + filename))Debug.Log("找到照片");elseDebug.Log("未找到");}/// <summary>/// Texture转换成Texture2D/// </summary>/// <param name="texture"></param>/// <returns></returns>private Texture2D TextureToTexture2D(Texture texture){Texture2D texture2D = new Texture2D(texture.width, texture.height, TextureFormat.RGBA32, false);RenderTexture currentRT = RenderTexture.active;RenderTexture renderTexture = RenderTexture.GetTemporary(texture.width, texture.height, 32);Graphics.Blit(texture, renderTexture);RenderTexture.active = renderTexture;texture2D.ReadPixels(new Rect(0, 0, renderTexture.width, renderTexture.height), 0, 0);texture2D.Apply();RenderTexture.active = currentRT;RenderTexture.ReleaseTemporary(renderTexture);return texture2D;}
}

效果如图

截图上面那张图让我不小心删了…
