捕捉来自网络摄像机的照片并存储在内存中或磁盘上。
演示如何使用 PhotoCapture 功能拍摄照片并将照片显示在 Unity 游戏对象上。
using UnityEngine; using System.Collections; using System.Linq; using UnityEngine.Windows.WebCam;
public class PhotoCaptureExample : MonoBehaviour { PhotoCapture photoCaptureObject = null; Texture2D targetTexture = null;
// Use this for initialization void Start() { Resolution cameraResolution = PhotoCapture.SupportedResolutions.OrderByDescending((res) => res.width * res.height).First(); targetTexture = new Texture2D(cameraResolution.width, cameraResolution.height);
// Create a PhotoCapture object PhotoCapture.CreateAsync(false, delegate(PhotoCapture captureObject) { photoCaptureObject = captureObject; CameraParameters cameraParameters = new CameraParameters(); cameraParameters.hologramOpacity = 0.0f; cameraParameters.cameraResolutionWidth = cameraResolution.width; cameraParameters.cameraResolutionHeight = cameraResolution.height; cameraParameters.pixelFormat = CapturePixelFormat.BGRA32;
// Activate the camera photoCaptureObject.StartPhotoModeAsync(cameraParameters, delegate(PhotoCapture.PhotoCaptureResult result) { // Take a picture photoCaptureObject.TakePhotoAsync(OnCapturedPhotoToMemory); }); }); }
void OnCapturedPhotoToMemory(PhotoCapture.PhotoCaptureResult result, PhotoCaptureFrame photoCaptureFrame) { // Copy the raw image data into our target texture photoCaptureFrame.UploadImageDataToTexture(targetTexture);
// Create a gameobject that we can apply our texture to GameObject quad = GameObject.CreatePrimitive(PrimitiveType.Quad); Renderer quadRenderer = quad.GetComponent<Renderer>() as Renderer; quadRenderer.material = new Material(Shader.Find("Unlit/Texture"));
quad.transform.parent = this.transform; quad.transform.localPosition = new Vector3(0.0f, 0.0f, 3.0f);
quadRenderer.material.SetTexture("_MainTex", targetTexture);
// Deactivate our camera photoCaptureObject.StopPhotoModeAsync(OnStoppedPhotoMode); }
void OnStoppedPhotoMode(PhotoCapture.PhotoCaptureResult result) { // Shutdown our photo capture resource photoCaptureObject.Dispose(); photoCaptureObject = null; } }
SupportedResolutions | 用于拍摄照片的所有受支持的设备分辨率列表。 |
Dispose | 必须调用 Dispose 来关闭 PhotoCapture 实例。 |
GetUnsafePointerToVideoDeviceController | 为原生 IVideoDeviceController 提供 COM 指针。 |
StartPhotoModeAsync | 异步启动照片模式。 |
StopPhotoModeAsync | 异步停止照片模式。 |
TakePhotoAsync | 使用网络摄像机异步捕捉照片并将照片存储在磁盘上。 |
CreateAsync | 异步创建可用于捕捉照片的 PhotoCapture 对象的实例。 |
OnCapturedToDiskCallback | 在照片被保存到文件系统时调用。 |
OnCapturedToMemoryCallback | 在照片被捕捉到内存中时调用。 |
OnCaptureResourceCreatedCallback | 在创建 PhotoCapture 资源时调用。 |
OnPhotoModeStartedCallback | 在照片模式启动时调用。 |
OnPhotoModeStoppedCallback | 在照片模式停止时调用。 |
