摘要:OpenNI 程式解讀

挑了一個看起來最單純的範例程式

C:\Program Files\OpenNI\Samples\NiSimpleRead

執行起來只有一個Console一直跑出數值

 

#include <XnOpenNI.h>
C:\Program Files\OpenNI\Include\XnOpenNI.h
 
#include <XnLog.h>
C:\Program Files\OpenNI\Include\XnLog.h
 
#include <XnCppWrapper.h>
C:\Program Files\OpenNI\Include\XnCppWrapper.h
 
#include <XnFPSCalculator.h>
C:\Program Files\OpenNI\Include\XnFPSCalculator.h
 
using namespace xn;
 
c:\Program Files\OpenNI\Include\XnStatus.h
 
設定檔 C:\Program Files\OpenNI\Data\SamplesConfig.xml

讓我們把這個最簡單的程式SimpleRead加到OGRE中

這裏岔個題, 我的VS2010 一直遇到錯誤訊息,

c1xx : fatal error C1027: Inconsistent values for /Ym between creation and use of precompiled header

如果你知道這個東東要怎麼解決, 歡迎你的指教...

 

我產生了一個空的Ogre專案, 在場景中放入一個Sinbad人物,

因為OpenNI要等待資料進來, 我們的Render又不能等, 所以要另外開一個thread給OpenNI

boost::thread(&OpenRzNIApp::openNIThread,this);

這個thread要一直讀depth的圖

nRetVal = ONIContext.WaitOneUpdateAll(ONIDepth);

因為讀進來的值有點跳動, 我做了一點smooth, 然後把它Mapping到適當的值域


	goodDepth = Rz::smoothToTarget(goodDepth,depthPoint,150.0f,evt.timeSinceLastFrame,10.0f);
	float remap = Rz::LinearClampBoth(goodDepth,0,1900,0,800);
	SinbadNode->setPosition(0,0,remap);

結果就像這樣

Sinbad會跟著我相對於攝影機移動而改變位置
