DllNotFoundException Occurs After Replacing opencvforunity.dll in OpenCVforUnity 2.6.5 with OpenCV 4.10.0 (CUDA Backend)

[youpenrai]

I followed the instructions in this guide to build OpenCV 4.10.0 for GPU acceleration in an OpenCVforUnity 2.6.5 Yolo v8 Segmentation project. I placed the built OpenCV as a native plugin and replaced the opencvforunity.dll, but I encountered a DllNotFoundException for opencvforunity.dll.

How can I resolve this issue?

Thank you for your report.
In my environment, the dll files created by the following procedure worked fine.

• Build the dll file with cuda enabled with the following settings: 65 dll files were generated.

• Copy the built group of files to the ‘Plugins/Windows/x86_64’ folder and set ImportSettings as in this image.

• Then replace the opencvforunity.dll file in the Extra package with opencvforunity.dll in the Plugins folder.
