以下是访问Hololens摄像头的代码示例:
```c#
using UnityEngine;
using UnityEngine.XR.WSA.WebCam;
public class CameraCapture : MonoBehaviour
{
PhotoCapture photoCaptureObject;
void Start()
{
// 创建PhotoCapture对象
PhotoCapture.CreateAsync(false, OnPhotoCaptureCreated);
}
void OnPhotoCaptureCreated(PhotoCapture captureObject)
{
photoCaptureObject = captureObject;
// 创建CameraParameters对象
CameraParameters cameraParameters = new CameraParameters();
cameraParameters.hologramOpacity = 0.0f;
cameraParameters.cameraResolutionWidth = 2048;
cameraParameters.cameraResolutionHeight = 2048;
cameraParameters.pixelFormat = CapturePixelFormat.BGRA32;
// 开始捕捉照片
photoCaptureObject.StartPhotoModeAsync(cameraParameters, OnPhotoModeStarted);
}
void OnPhotoModeStarted(PhotoCapture.PhotoCaptureResult result)
{
if (result.success)
{
// 捕捉照片
photoCaptureObject.TakePhotoAsync(OnCapturedPhotoToMemory);
}
else
{
Debug.LogError("无法启动照相模式");
}
}
void OnCapturedPhotoToMemory(PhotoCapture.PhotoCaptureResult result, PhotoCaptureFrame photoCaptureFrame)
{
if (result.success)
{
// 获取照片数据
byte[] imageBuffer = null;
photoCaptureFrame.CopyRawImageDataIntoBuffer(out imageBuffer);
// 创建Texture2D对象
Texture2D tex = new Texture2D(2, 2);
tex.LoadImage(imageBuffer);
// 在屏幕上显示照片
GetComponent<Renderer>().material.mainTexture = tex;
}
// 停止照相模式
photoCaptureObject.StopPhotoModeAsync(OnStoppedPhotoMode);
}
void OnStoppedPhotoMode(PhotoCapture.PhotoCaptureResult result)
{
// 释放PhotoCapture对象
photoCaptureObject.Dispose();
photoCaptureObject = null;
}
}
```
这个示例演示了如何使用Hololens摄像头捕捉照片。它使用PhotoCapture类来访问摄像头,并使用CameraParameters类来设置摄像头参数。在OnCapturedPhotoToMemory回调中,它获取了照片数据,并使用Texture2D类将其呈现在屏幕上。最后,在OnStoppedPhotoMode回调中释放了PhotoCapture对象。
