我正在使用官方 Kinect SDK 1.5 示例之一,我正在尝试了解如何添加检查以检测 Kinect 何时断开连接。目前,该应用程序只会卡住,因此必须有一种方法来防止这种情况发生。
这是来自 SDK 示例的主要消息循环:
// Main message loop
while (WM_QUIT != msg.message)
{
hEvents[0] = m_hNextDepthFrameEvent;
// Check to see if we have either a message (by passing in QS_ALLINPUT)
// Or a Kinect event (hEvents)
// Update() will check for Kinect events individually, in case more than one are signalled
DWORD dwEvent = MsgWaitForMultipleObjects(eventCount, hEvents, FALSE, INFINITE, QS_ALLINPUT);
// Check if this is an event we're waiting on and not a timeout or message
if (WAIT_OBJECT_0 == dwEvent)
{
Update();
}
// does not work.
bool bla = m_pNuiSensor->NuiStatus();
if (NULL == m_pNuiSensor)
{
cout << 1 << endl;
}
if (PeekMessageW(&msg, NULL, 0, 0, PM_REMOVE))
{
// If a dialog message will be taken care of by the dialog proc
if ((hWndApp != NULL) && IsDialogMessageW(hWndApp, &msg))
{
continue;
}
TranslateMessage(&msg);
DispatchMessageW(&msg);
}
}
return static_cast<int>(msg.wParam);
我添加了以下内容:
// does not work, bla will always be the same value.
bool bla = m_pNuiSensor->NuiStatus();
if (NULL == m_pNuiSensor)
{
cout << 1 << endl;
}
因为我假设 NuiStatus
可能是一种检测断开连接的方法。不幸的是它不会工作。检查m_pNuiSensor
是否为NULL
也是如此。
那么检测正在运行的应用程序断开连接的方法是什么?
EDIT1:我应该使用 NuiSetDeviceStatusCallback
吗?
最佳答案
在documentation它说 NuiStatus 返回 HRESULT 而不是 bool,所以它不应该是
HRESULT bla = m_pNuiSensor->NuiStatus();
if (bla == E_NUI_NOTCONNECTED)
{
cout << 1 << endl;
}
代替?
