Cannot verify interface compatibility of device adapter

[yuegew]

i write a device adapter for the Daheng camera. And when i test it, i find this error "Cannot verify interface compatibility of device adapter""Line 2: run-time error : Failed to load device "DCam" from adapter module "Dahengcameratest" [ Failed to load device adapter "Dahengcameratest" from "C:\Program Files\Micro-Manager-2.0\mmgr_dal_Dahengcameratest.dll" [ Cannot verify interface compatibility of device adapter [ Cannot find function GetModuleVersion() in module "C:\Program Files\Micro-Manager-2.0\mmgr_dal_Dahengcameratest.dll" [ ÕҲ»µ½ָ¶¨µijÌÐò¡£" Do you know what it mains? Thankyou very much.

The most likely explanation is that your device adapter is not correctly linking to MMDevice-SharedRuntime.

Thank you very much. I think i fixed this issue by adding the MODULE_API function. However, i encounter another problem. I open and run through the configuration of the device, but when i run through the step of opening the GUI, the micromanager crashed. The log is here.

The expossure time and the height and width of the device is right. I wonder wheter the 3rd party drive is link to the device ,but the expossure time and the height and width of the device is right. Then i try using script to load the device and it returns this.

Do you know what it means?

[marktsuchida]

From your first log, it looks like your device is correctly instantiated and its Initialize() function was successfully called. After Initialize(), other functions of your device may be called by Micro-Manager to interact with the device, and it is not possible to tell from the log which of them caused the crash.

I would recommend building your device adapter in Debug configuration and attaching the Visual Studio debugger before configuring the device. This should allow you to debug the crash.

As for your second log, I cannot interpret the error without knowing the exact script you ran.

[yuegew]

Thank you so much! I will try this very soon.

[yuegew]

Thank you very much. I think I solove the issue of the micromanager crashed. Unfortunately, when I snap an image , there is an "Missing pixel type in Thread" problem. And when i use live image the interface didn't open. The corelog is here

I'm wondering what is related to it and want to get some supports from you, thank you very much.

[marktsuchida]

If it has something to do with pixel type, make sure that your camera's GetImageBytesPerPixel() returns 1 (8-bit gray), 2 (16-bit gray), or 4 (RGB). Correspondingly, GetNumberOfComponents() must return 1, 1, or 4, respectively. In contrast, GetBitDepth() is supposed to return the actual bit depth, independent of the pixel format (e.g., a 16-bit pixel might contain 14-bit data).

[yuegew]

Thank you very much! I think now I can open the device and grab the picture. But now I encounter another problem. The device only have 24 bits RGB, but the micromanager shows that it is 32 bits RGB, and the color of the picture seems to be raw data of bayer rg8, but I think i do convert the pixel format. I wonder how I can solve the problem. And the following is how I(not MM) convert and show the picture, it works well.

img.create(objImageDataPointer->GetHeight(), objImageDataPointer->GetWidth(), CV_8UC3);
pRGB24Buffer = objImageDataPointer->ConvertToRGB24(GX_BIT_0_7, GX_RAW2RGB_NEIGHBOUR, true);
memcpy(img.data, pRGB24Buffer, (objImageDataPointer->GetHeight()) * (objImageDataPointer->GetWidth()) * 3);
cv::flip(img, img, 0);
cv::imshow("www", img);
cv::waitKey(1);

[marktsuchida]

For historical reasons, the required format for RGB images is BGRA32. The extra 'A' component is not used, and should be set to zero. It is best to test your code by pointing the camera to blue or red objects (e.g. an LCD screen showing those colors) to confirm that you have the components in the correct order.

So I think you need to convert your image to RGB (debayer), and then to BGRA32. There are functions in MMDevice/Debayer.h that you can use for debayering (instead of OpenCV). These functions will generate the BGRA32 format directly, if I remember correctly.

[yuegew]

Thank you very much ,i follow your step and it turn out that this return a very good result , i can now run the camera in 32 bit RGB Howerver, i have to use scaneimage ,it only support device that GetImageBytesPerPixel() returns 1 (8-bit gray), 2 (16-bit gray). I wonder how i can show colored image with this， maybe 16bit RGB or 8bit RGB?

[marktsuchida]

Great to hear it worked!

MMDevice/MMCore does not support RGB with fewer than 8 bits per component. You could convert your images to 16-bit grayscale, at least to get a preview. You will have to ask the ScanImage people about their RGB image support.

[marktsuchida]

Considering this solved; please open a new issue if necessary.
