A state of the art real-time human social distance detection system for C# (Visual Studio). This project has CPU and GPU support, with GPU the detection works much faster. In the background we use the Windows Yolo version of AlexeyAB/darknet. Send an image path or the byte array to yolo and receive the position of the detected objects. Our project is meant to return the object-type -position and -distance as processable data. This library supports YoloV3 and YoloV2 Pre-Trained Datasets
It is important to use GPU mode for fast object detection. It is also important not to instantiate the wrapper over and over again. A further optimization is to transfer the images as byte stream instead of passing a file path. GPU detection is usually 10 times faster!
- 64-bit CPU architechture
- .NET Framework 4.6.1 or .NET standard 2.0
- Microsoft Visual C++ Redistributable for Visual Studio 2015, 2017 und 2019 x64
It is important to use the mentioned version 10.2
- Install the latest Nvidia driver for your graphic device
- Install Nvidia CUDA Toolkit 10.2 (must be installed add a hardware driver for cuda support)
- Download Nvidia cuDNN v7.6.5 for CUDA 10.2
- Copy the
cudnn64_7.dllfrom the output directory of point 2. into the project folder.

If you have some error like DllNotFoundException use Dependencies to check all references are available for yolo_cpp_dll_gpu.dll
If you have some error like NotSupportedException check if you use the latest Nvidia driver
Check graphic device usage "%PROGRAMFILES%\NVIDIA Corporation\NVSMI\nvidia-smi.exe"
