Fingerdata Foldness

Debabrata_B_ — Thu, 26 Mar 2015 12:08:09 GMT

Hello,

I am newbie to Realsense . I just have started writing application one week back. I wanted to track the foldness of my index finger by a small program(as pasted below) . But unfortunately I am always getting zero. As I as seen in definition of foldness it should range from 0 to 100. What I am missing here? Can anybody help please.

Regards,

void CFaceProcessor::processHand()
{
   PXCSenseManager *psm = getSenseManager();
   psm->EnableStream(PXCCapture::STREAM_TYPE_DEPTH, 640, 480, 30);
   psm->EnableHand();
   PXCHandModule *handAnalyzer = NULL;
   while (!(handAnalyzer = psm->QueryHand())){
       std::cout << "wating...\n";
       Sleep(1);
   }
   if (psm->Init() < PXC_STATUS_NO_ERROR) {
       return;
   }
   PXCHandData* outputData = handAnalyzer->CreateOutput();
   PXCHandConfiguration* config = handAnalyzer->CreateActiveConfiguration();
   config->EnableNormalizedJoints(true);
   config->SetTrackingMode(PXCHandData::TRACKING_MODE_EXTREMITIES);
   config->EnableAllGestures();
   config->ApplyChanges();
   config->Update();
   pxcI32 foldnessOld = -1;
   while (psm->AcquireFrame(true) >= PXC_STATUS_NO_ERROR){
       outputData->Update();
       pxcU16 numOfHands = outputData->QueryNumberOfHands();
       PXCHandData::IHand* handData;
       for (int i = 0; i < numOfHands; i++){
           if (outputData->QueryHandData(PXCHandData::AccessOrderType::ACCESS_ORDER_BY_TIME, i, handData)
               == PXC_STATUS_NO_ERROR)
           {

                       == PXC_STATUS_NO_ERROR){

                           foldnessOld = foldess;
                       }

are you using R2 (v4.0) of the RSSDK?

I dont know how exactly it

Debabrata_B_ — Thu, 26 Mar 2015 17:24:28 GMT

I dont know how exactly it should be checked but in the directory C:\Program Files (x86)\Intel\RSSDK\runtime I can notice the binary installed is intel_rs_sdk_runtime_3.1.085181.exe . This binary I downloaded from this Intel site. If it is not the correct version then please let me know the link from where i can download the correct version. Debabrata

https://software.intel.com/en-us/intel-realsense-sdk has the 4.0 version.

Did you download 3.1 recently? or just didn't update with the new software available for just over a month now?

Yes! I downloaded very

Debabrata_B_ — Thu, 26 Mar 2015 18:31:35 GMT

Yes! I downloaded very recently( 1 or 2 week(s) ago) . But at that time my System was windows 7 with core i3 processor. Looking at RealSense requirement , I Upgraded my system to windows 8 and core i5 one week back and used the same installer binary .

And Thanks a lot for you quick support.

Hello.

I updated with the new RealSense 4 as you have said. But unfortunately the result is same. Also

outputData->QueryFiredGesturesNumber(); is returning zero for any gesture like indexfinger,thunb etc etc. Can you help me by pointing out what I am doing wrong?

The extremeties are indeed

The extremeties are indeed edge points of the hand. You can read about the extremity points at : https://software.intel.com/sites/landingpage/realsense/camera-sdk/2014gold/documentation/html/index.html?extremitytype_pxchanddata.html

and you can see the other options (and the comparative speeds) including finger and hand openness @
