Possible SDK bug in 5.2.1

Software C#
1

When using the SDK 5.2.1 in combination with the .NET/c# bindings the following command now returns an sl.ERROR_CODE.INVALID_FUNCTION_PARAMETERS error code where it would work fine with SDK 5.1:

s.Camera.RetrieveImage ( Buf, sl.VIEW.LEFT_BGR );

Then, immediately after the sl_zed64.dll irreparably crashes the whole process with this exception:

`Exception thrown at 0x00007FFDCA5BA80A in ZED_Depth_Sensing.exe: Microsoft C++ exception: std::system_error at memory location 0x000000D4471EF8E0

And this call stack:

```
KernelBase.dll!00007ffdca5ba80a() Unknown
vcruntime140.dll!00007ffda2815277() Unknown
msvcp140.dll!00007ffda2792c96() Unknown

sl_zed64.dll!00007ffc7cf7d90b() Unknown
sl_zed_c.dll!00007ffd9392ed5a() Unknown
```

I am testing using a ZED 2i camera.

It’s fairly ease to reproduce this by modifying the SDK’s ZED_Depth_Sensing sample code as follows:

At line 168 of mainwindow.cs, insert:

var Res = new sl.Resolution ( zedCamera.ImageWidth, zedCamera.ImageHeight );
var Buf = new sl.Mat ();
Buf.Create ( Res, sl.MAT_TYPE.MAT_8U_C3, sl.MEM.CPU );
var Result = zedCamera.RetrieveImage ( Buf, sl.VIEW.LEFT_BGR );

Then run the example using SDK 5.2.1 and witness the error code and subsequent crash.

Hi,

Thanks for the report.

I tested and confirm the issue, which was a combination of a bug in the SDK and in the wrapper itself).
I’ll update the wrappers soonso you’ll be able to retrieve the LEFT_BGR image. The underlying crash will be addressed in the next patch of the ZED SDK.
