The problem here is that version of opencv distributed with your system (Windows in this case) was not compiled with Cuda support.

You must install OpenCV for GPU if your system allows you. OpenCV library can be used for both CPU and GPU, but if you just install OpenCV by “pip” or “conda” command ( pip install opencv-python) it will use CPU as a backend by default.

If you are working on deep learning or real-time video processing project using Opencv (like Object Detection, Social Distance detection), you will face lags in the output video (less frame rate per second), you can fix this lag using GPU if your system has NVIDIA GPU (NVIDIA Graphics card). OpenCV library can be used for both CPU and GPU.

OpenCV includes GPU module that contains all GPU accelerated stuff. Supported by NVIDIA the work on the module, started in 2010 prior to the first release ...

Jan 08, 2013 · GPU-Accelerated Computer Vision (cuda module) Squeeze out every little computation power from your system by using the power of your video card to run the OpenCV algorithms. This will give a good grasp on how to approach coding on the GPU module, once you already know how to handle the other modules. As a test case it will port the similarity ...

... you can fix this lag using GPU if your system has NVIDIA GPU (NVIDIA Graphics card). OpenCV library can be used for both CPU and GPU.

Use Opencv with GPU with just 2 lines of code. If you are working on deep learning or real-time video processing project using Opencv (like Object Detection, Social Distance detection), you will face lags in the output video (less frame rate per second), you can fix this lag using GPU if your system has NVIDIA GPU (NVIDIA Graphics card).

30.03.2021 · openCV GPU usage disappoints… Use the GPU with your openCV code, get performance gains… Not! Peter Gaston Mar 30 · 3 min read Several times I’ve been drawn to the siren call of using key openCV calls on the GPU. Most recently for the matchTemplate call — before that for calls relating to visual odometry. Ah, disappointment!
