camera-cuda

This is a repo that integrate multiple image processing algos on CUDA-based acceleration with bazel build

There are some cuda-based algorithms covered in this repos, such as HDR, Scaler, Resize, Rotater and Edge Detector etc., which will be updated and iterated from time to time.

Maybe, GDC, DVS, Deblur or anothers image processing algos will be added one by one in the future.

I expect camera-cuda to be used as an image processing library, or be viewed as a middleware, to be called by the camera driver to implement application layer functions.

Setup Environment

Step1: Please make sure to download the executor file of Bazel version 6.2.0 or above

Step2: Please add the path of bazel.exe as environment variables

Step3: Please make sure to install VS2019 and above and add the path as environment variables

Step4: Please make sure to install CUDA 12.4 and cuDNN 9.2.0 and add the path as environment variables

Step5: Please make sure you downloads camera-supp

$ git clone https://github.com/cuiyixin555/camera-supp

$ cd camera-supp

$ git lfs pull

Step6: Please make sure the repo of camera-cuda and camera-supp in same directory

Step7: Please add the path of camera-supp as Win11 environment value

The bazel.exe path is

C:\Users\admin\OneDrive\Desktop\workspace\camera-supp\build_tools\windows\bazel.exe

Note: Hardware Configuration is GeForce 4090 24G
