CameraWithCVAndCalibration not working! #96

Open Julian243 opened 2 years ago

Julian243 commented 2 years ago

Hello,

I've been trying to get the CameraWithCVAndCalibration sample to work for the past two days. However I still haven't succeded yet. Opening the sln-file I got the error: LNK1104 cannot open file 'opencv_world412d.lib' so I manually added the path to the .lib-file under Properties->Configuration Properties->VC++ Directories->Library Directories. Trying to deploy the project to HoloLens2 as Debug|ARM64 configuration results in the following two errors: error1 error2 And yes I did use git lfs clone to clone the repository! Can anyone please help me? I spend hours trying to figure out where things went wrong and still have no clue... I tried out different PC's and even factory resetted my HoloLens2. Other examples work just fine but I can't get this to work.

Thanks in advance!

Edit: The console shows the following output. Could it be that there might be a dll reference missing?

Update: Checking out an earlier version of this repository solved the issue for me! I checked out commit 41ec9e542a7a84b3a68e5089b9906864bc7c526a which contains the missing lib files in the staticlib folder. Please fix this!

Thanks a lot for the solution. Don‘t understand why the authors delete the library.

Downloading the previous commit didn't help with the OpenCV lib issue. :/ Could anyone clarify how they got the CameraWithCVAndCalibration app to work? Thank you in advance!

Thanks for the pointer for using this older commit. Hope the fixing PR https://github.com/microsoft/HoloLens2ForCV/pull/120 gets merged soon.

I'm able to build the app now, but get the following run time error after deploying to my HL2:

Exception thrown at 0x00007FFD9D8C5E5C (KernelBase.dll) in CameraWithCVAndCalibration.exe: WinRT originate error - 0x8000FFFF : 'Catastrophic failure'.
Exception thrown at 0x00007FFD9D8C5E5C in CameraWithCVAndCalibration.exe: Microsoft C++ exception: winrt::hresult_error at memory location 0x00000021234FD290.

Anyone else has this problem?

@friederwC I had the same problem. I realized research mode was not enabled on my HoloLens 2. Make sure you have research mode enabled.
