    This demo was part of a set of demonstrations from the CES 2020 show.

    https://www.intelrealsense.com/lidar-camera-l515-at-ces-2020/ 

    I researched carefully but could not find any announcements about the software that the box measurement demo was based on (though there are commercial box dimensioning solutions for the RealSense 400 Series cameras that it could have been based on). So it may be a tool that will be made available with L515 compatibility at a later date.  This is pure speculation though.

    Hi again Carld  I remembered that you asked about box measuring with L515.  On Wednesday August 5 2020, Intel are holding an online RealSense webinar session about logistics, and during this event they are planning to show the L515 and introduce their software solution for box and pallet measurement.

    I would also be really interested by this code.

    Hello 

    Does Intel plan to release a Python Wrapper for this SDK? Thank you

    Hi Henry,  If you mean the Dimensional Weight Software SDK: though it uses the L515 camera, my understanding is that it is a standalone software that is not connected to the RealSense SDK.  It requires Windows 10 and is integrated into a project simply by linking the project to a DLL file of the Dimensional Weight Software.

    The full details of installation are explained in a data sheet document for the Dimensional Weight Software that can be downloaded as a PDF file in your web browser by left-clicking on the link below.

    Thank you Marty for getting back to me. I have read the doc. I believe that the DWS SDK is a C++ library in DLL file. Is that correct? I have not done this before but I don't think I can use C++ library in the Python program. Maybe it is possible, do you know?

    The manual does seem to be orientated towards C++ use.  DLLs can be accessed from non-C++ applications.  In Python that can be done with ctypes.

    Thank you @MartyG. I got the SDK and read the doc!
    Is there a procedure from scratch to call the dim api from a C# app?

    C++ DLL library files can be called from C# using a "native" method called Pinvoke.

    https://docs.microsoft.com/en-us/dotnet/standard/native-interop/pinvoke 

    The librealsense SDK makes use of Pinvoke in its C# wrapper to communicate with the SDK's C++ based DLL files.

    Hello Marty

    The doc says "Link the DWS_Sdk.dll to your project. " I just cannot find this file in the downloads. Is this file generated? If it in the SDK download, could you tell me the path? Thank you so much.

    Hi Henry, the documentation says that the DLL should be in the 'download folder'.  I would recommend finding the file by going to the top folder of the program folder and doing a file search in the folder's search box for the term dws_sdk.dll

    Hello Marty 

    Do you see the file? Because I have download the folder 3 times and double-checked and it is not there. The closest thing I can find is "DIM3DSDK.dll". Is this the one?

    Best

    Hi Henry, I haven't been able to receive a download code by email after registering for a trial version, so I haven't been able to check the file contents.  This is a question that is likely best handled on the RealSense GitHub forum anyhow, as that is the forum that is responsible for L515 related tech support.
