Calibration Data from R200

[idata]

Hi,

I recently started working with Intel RealSense R200 camera. I am having issues in accessing data from R200 using the member functions QueryStreamProjectionParameters and QueryStreamProjectionParametersEx. Whenever I use these two functions to get the calibration data they either return "PXCM_STATUS_FEATURE_UNSUPPORTED" and "PXCM_STATUS_DATA_UNAVAILABLE". Any help would be much appreciated.

Part of the code I am using to get Calibration Data:

sm.EnableStream(PXCMCapture.StreamType.STREAM_TYPE_DEPTH, 0, 0, 0); SetStatus("Init Started");if (sm.Init() >= pxcmStatus.PXCM_STATUS_NO_ERROR) { /* Reset all properties */ sm.captureManager.device.ResetProperties(PXCMCapture.StreamType.STREAM_TYPE_ANY); PXCMProjection projection = sm.captureManager.device.CreateProjection(); PXCMCalibration calib = projection.QueryInstance<<span style="color: # 2b91af;">PXCMCalibration>(); PXCMCalibration.StreamCalibration calibData; PXCMCalibration.StreamTransform calibTrans; SetStatus(calib.QueryStreamProjectionParameters(PXCMCapture.StreamType.STREAM_TYPE_COLOR, out calibData, out calibTrans).ToString());

Hello TulasiSunil,

Thanks for reaching out!

Could you please let us know which version of the SDK you are using?

In case you are using version R3 of the SDK, please note that the R200 is not supported on this release, therefore this behavior could be explained by that.

I've checked pxcmstatus.cs (https://github.com/SharpSenses/libpxcclr.cs/blob/master/src/pxcmstatus.cs libpxcclr.cs/pxcmstatus.cs at master · SharpSenses/libpxcclr.cs · GitHub) and it states that pxcmStatus value, if it is different than 0 it indicates an error, in this case PXCM_STATUS_FEATURE_UNSUPPORTED is -1 and PXCM_STATUS_DATA_UNAVAILABLE is -501. So, something might be wrong on your application.

PXCM_STATUS_DATA_UNAVAILABLE in pxcmblobdata.cs (https://github.com/SharpSenses/libpxcclr.cs/blob/master/src/pxcmblobdata.cs libpxcclr.cs/pxcmblobdata.cs at master · SharpSenses/libpxcclr.cs · GitHub) it is stated that the segmentation image is not available. You might want to take a look this files.

Let us know.

-Peter.

Hello Peter,

I really appreciate your reply. It was very helpful. I was able to fix the Issue and get all the calibration data by using R2 SDK.
