PXC3DScan::QueryTrackingTransformation not available

[Eduard_R_1]

Hi all,

I am using the 3DScan module and I am trying to access to the camera pose through the method QueryTrackingTransformation. Unfortunately the compiler says:

"PXC3DScan" has no member function "QueryTrackingTransformation"

Anyone with the same problem? Thanks in advance,

Eduard.

Nobody?

Hi Eduard,

Can you find the function "QueryTrackingTransformation" in documents ?

Thanks,

Zachary

Hi Zachary,

Thanks for your response. What do you mean by "documents"? I refer to the function documented in here:

https://software.intel.com/sites/landingpage/realsense/camera-sdk/v1.1/documentation/html/index.html?querytrackingtransformation_pxc3dscan.html

I installed the Realsense SDK R2 with all the modules. When trying to access to QueryTrackingTransformation from the 3DScan module the compiler says it is not a member function. Shouldn't it be?

Best regards,

Eduard.

Any news?

Hi,    we need more information in order to investigate this issue, such as RS SDK version, development tool(IDE), target OS(Windows 10?), etc. Thanks.

Hi Bilel,

Thanks for your answer. We are using Realsense SDK R2 on windows 10. Our hardware is a Realsense R200 camera and we're using Microsoft Visual Studio as IDE.

We got support directly from Intel Customer Care team, I paste their answer:

"Currently, there is no way to get camera pose information from 3D scan. However, in the next SDK release of the 3D Scan module in about a month, they will add this capability in a function called TransformPointWithTrackingTransform. It will 

"Transform the Point with TrackingTransform which transforms pt from Object/World to Camera Coordinate system."

The function you mentioned: QueryTransformTracking is actually not implemented and is in the documentation by mistake.  Actually, the upcoming function I mentioned above, TransformPointWithTrackingTransform, is the correct and full implementation of QueryTransformTracking.

So, short answer, in about a month the RealSense SDK will support a get-camera-pose type function called TransformPointWithTrackingTransform."

As they mention, the function QueryTrackingTransformation appears in the documentation but it is not implemented. Nevertheless, they mention that they will add another function in newer SDKs called TransformPointWithTrackingTransform with this signature:

virtual  Status PXCAPI TransformPointWithTrackingTransform( PXCPoint3DF32* point ) = 0;

This function will allow us to map points from 3D to 2D but it still hides what is more relevant to most of the developers, the camera pose and the intrinsic parameters of the cameras. It would be very useful to get full access to the cameras used by tracker.

Thank you very much,

Eduard.
