Question on D405

Follow
Redyoung
Hi I have VB .NET program that works fine with D455 and D435. But when I use it with D405, it gives me error at pipeline.start(configuration) with a message that memory access violation. It looks like there are some issue with 'pipeline' based on the way the program was written.. Are there common issues or new features of D405 that need to address? Any help would be appreciated! Thanks!

    Hi Redyoung   A key difference between D405 and D435 / D455 is that the D405 model does not have a separate RGB sensor, as RGB is instead provided by the depth sensor.  So a program may fail on D405 if the code has a check to see whether an RGB sensor can be detected.  That is an error that would not usually be triggered by the cfg / configuration part of the script though.

     

    Could you post the 'configuration' lines from your script in a comment, please?  Thanks!

    Dim pipeline As New Pipeline
    Dim cif As New Config

    cif.Enablestream(Intel.Realsense.Stream.Depth, 640, 480, format.Z16, 60)
    cif.Enablestream(Intel.Realsense.Stream.Infrared, 640, 480, format.Y8, 60)
    cif.Enablestream(Intel.Realsense.Stream.Color, 640, 480, format.Bgr8, 60)
    cif.EnableDivce (serialNumber)
    pipeline.Start(cif)

    Above are lines that make D435/D455 running but does not work with D405. I tried without colorstreaming and the result was the same.
    Thanks in advance for your help here!

    Does the code below work?

     

    var pipeline = new Pipeline();

    var cfg = new Config();

    cif.EnableStream(Stream.Depth, 640, 480, Format.Z16, 60);

    cif.EnableStream(Stream.Infrared, 640, 480, Format.Y8, 60);

    cif.EnableStream(Stream.Color, 640, 480, Format.RGB8, 60);

    cif.EnableDevice(serialNumber);

    pipeline.Start(cif);

    Thank you for the code..
    This is basically same as what I posted I think. And this works for D435/455 but not for D405 as I mentioned earlier.

    Let's test whether it really is a stream configuration issue by removing cif from the brackets of the pipeline start line.  The program should then ignore the cif lines and launch the D405 with its default stream configuration profile.

     

    pipeline.Start();

    Thanks MartyG for suggestion. I already did and did not work. Interestingly, if I use similar code in Phyton, it works fine...

    Assuming then that the problem is not with the cif configuration lines, I recall a D405 case from October 2022 where a RealSense user of C# had a crash error with D405 that did not occur with D435.

    Are you using the x86 or x64 version of the RealSense DLLs with the C# wrapper?   In RealSense SDK 2.50.0 there was a D405-specific crash problem when using D405 with the x86 DLLs (x64 worked fine) that was fixed in SDK 2.51.1.

    I am using SDK 2.49/2.5 I believe. I will try SDK 2.51.1 and report back to you.
    Thanks!

    This error can occur if the target platform has been set to 'Any CPU' instead of x86 or x64.
