Sure, I'd be happy to help you with that. Installing OpenCV with CUDA support on Windows can be a bit challenging, but I'll guide you through the process step by step. CUDA is a parallel computing platform and application programming interface model created by Nvidia, which can significantly accelerate certain operations in OpenCV.
Before you start, make sure you have a compatible Nvidia GPU and have installed the latest Nvidia CUDA Toolkit and cuDNN library.
Step 1: Install Visual Studio
OpenCV with CUDA requires a compatible version of Visual Studio. As of my last knowledge update in January 2022, you can use Visual Studio 2019.
Download and install Visual Studio 2019 from the official Microsoft website: Visual Studio
During installation, make sure to select the "Desktop development with C++" workload.
Step 2: Install CUDA Toolkit and cuDNN
Download and install the latest version of the Nvidia CUDA Toolkit and cuDNN library:
Follow the installation instructions provided by Nvidia for each package.
Step 3: Install Python and required packages
Install Python and some required packages using pip:
Step 4: Install OpenCV with CUDA support
Now, let's install OpenCV with CUDA support. Open a command prompt or terminal and run the following command:
This will install the regular OpenCV package. Now, we need to install the OpenCV with CUDA support. You can use a precompiled version available on the unofficial repository lucasg/Dependencies:
Step 5: Test your installation
Now, let's create a simple Python script to test if OpenCV with CUDA is working correctly:
Replace 'path/to/your/image.jpg' with the path to your image file. Save the script and run it. If everything is set up correctly, you should see a window displaying the thresholded version of your image.
Congratulations! You've successfully installed OpenCV with CUDA support on Windows.
