请写一段使用Kinect进行测距的c++代码

我们可以使用下面的C代码来进行测距：#include <Kinect.h>
#include <iostream>int main()
{
// 创建Kinect对象
IKinectSensor* pSensor = nullptr;
HRESULT hr = ::CoCreateInstance( CLSID_KinectSensor, nullptr, CLSCTX_INPROC_SERVER,
IID_PPV_ARGS(&pSensor)); // 打开Kinect
if(SUCCEEDED(hr))
{
hr = pSensor->Open();
} // 获取深度帧
IDepthFrameSource* pDepthSource = nullptr;
if(SUCCEEDED(hr))
{
hr = pSensor->get_DepthFrameSource(&pDepthSource);
} // 获取深度数据
IDepthFrameReader* pDepthReader = nullptr;
if(SUCCEEDED(hr))
{
hr = pDepthSource->OpenReader(&pDepthReader);
} // 读取深度数据
IDepthFrame* pDepthFrame = nullptr;
if(SUCCEEDED(hr))
{
hr = pDepthReader->AcquireLatestFrame(&pDepthFrame);
} // 获取深度数据
UINT nBufferSize = 0;
UINT16* pBuffer = nullptr;
if(SUCCEEDED(hr))
{
hr = pDepthFrame->AccessUnderlyingBuffer(&nBufferSize, &pBuffer);
} // 计算深度
if(SUCCEEDED(hr))
{
for (UINT i = 0; i < nBufferSize; ++i)
{
UINT16 depth = pBuffer[i] >> 3;
// Use the depth value to calculate the distance
// in meters...
}
} SafeRelease(pDepthFrame);
SafeRelease(pDepthReader);
SafeRelease(pDepthSource);
SafeRelease(pSensor); return 0;
}
