Getting SYNC image

[YDai2]

Hi,when I try to get the depth ,IR, color image with SR300, but there is nothing int Sample struct , my code is based on the SDK Example 17, So any ideas of how to accomplish it? many thanks.

here is my code:

int main(){

PXCImage *IR;

PXCImage *Depth;

PXCImage::ImageData IRdata;

pxcStatus sts;

PXCCapture::Sample *sample;

PXCSenseManager *pp=PXCSenseManager::CreateInstance();

pp->EnableStream(PXCCapture::STREAM_TYPE_DEPTH,0,0,0,PXCCapture::Device::STREAM_OPTION_STRONG_STREAM_SYNC);

pp->EnableStream(PXCCapture::STREAM_TYPE_IR,0,0,0,PXCCapture::Device::STREAM_OPTION_STRONG_STREAM_SYNC);

pp->EnableStream(PXCCapture::STREAM_TYPE_COLOR,0,0,0,PXCCapture::Device::STREAM_OPTION_STRONG_STREAM_SYNC);

pp->Init();

PXCCapture::Device *device = pp->QueryCaptureManager()->QueryDevice();

device->ResetProperties(PXCCapture::STREAM_TYPE_ANY);

device->SetMirrorMode(PXCCapture::Device::MirrorMode::MIRROR_MODE_DISABLED);

for(int i=0;i<1;i++)

{

sts=pp->AcquireFrame(true);

sample= pp->QuerySample();

IR = (*sample)[PXCCapture::STREAM_TYPE_IR];

Depth = (*sample)[PXCCapture::STREAM_TYPE_DEPTH];

IR ->AcquireAccess(PXCImage::ACCESS_WRITE,&IRdata);

pp->ReleaseFrame();

}

return 0;

}

Hi Div3,

Thank you for contacting us.From what I understand from your case, you're looking at https://software.intel.com/sites/landingpage/realsense/camera-sdk/v1.1/documentation/html/index.html?doc_essential_strong_synchronization.html as a reference to build your code, and your goal is to enable strong synchronization, right? We'd like to do a bit of research before providing a suggestion. Could you tell us more information about your environment such as DCM version, SDK Release version, is the error from the picture you posted the only message you receive, are there additional error logs. The more information you can provide, the better.Regards,-Sergio A

Hi, Sergio,

thanks for your reply. You are right, I would like to get the IR,depth images with closest time stamp,and do some further treatment with them,here is the detailed information:

--------------------------

SDK :10.0.26.396

DCM:3.3.27.5718

OS:windows 10

Programming platform: VS2012

---------------------------------

when the code exercises at

IR->AcquireAccess(PXCImage::ACCESS_WRITE,PXCImage::PIXEL_FORMAT_Y16,&IRdata);

Sorry, I have no English version of VS2012. theThrew error means "An access violation occurred while reading location '0x00000000'"

and the error seams comes from the "pxcimage.h"

On the face of this problem,get nothing from after exercise code

sts=pp->AcquireFrame(true);sample= pp->QuerySample();

when I change the parameter of function to "false", only "depth" of "sample" has data.

and then, I remove the option "PXCCapture::Device::STREAM_OPTION_STRONG_STREAM_SYNC",all the streams I enabled has data,

but this is not what I need, So it is a little weird. any further information requirement, please that me know. thanks a lot.

Hi Div3,

Thank you for your patience. We've been working on your case and noticed that you're looking at only one frame as seen in this statement for(int i=0;i<1;i++). You should try capturing more frames for sync to happen. You can test your code with the CameraViewer sample.<p> Let us know your results. -Sergio A
