Xavier OpenCV4 cudaimgproc.hpp

I have used SDK manager to configure/install the Jetson Xavier AGX, and have OpenCV version 4.1.1 installed.

This is the cmake file using for my C++ codes:

cmake_minimum_required (VERSION 3.0)

set(CMAKE_CXX_STANDARD 17)

project(xiapi_test_1)

find_package(OpenCV REQUIRED)

include_directories(“/usr/include/opencv4/”)

add_executable(xiapi_test_1 xiapi_test_1.cpp)

target_link_libraries(xiapi_test_1 ${OpenCV_LIBS} -lm3api)

cmake, make and most of my C++ codes work, with cv::demosaicing. But when try to use the cuda assisted function cv::cuda::demosaicing, getting this error:

fatal error: opencv2/cudaimgproc.hpp: No such file or directory
include <opencv2/cudaimgproc.hpp>
compilation terminated.

please note that opencv2/cudaimgproc.hpp is the required library for cv::cuda::demosaicing

When I check the usr/include/opencv4/opencv2 folder see this:

no cudaimgproc.hpp file exist??

is this normal, or am I making a mistake?

IF your application needs CUDA supported OpenCV, you should build OpenCV by yourself.
OpenCV 4.1.1 installed by SDK manager may not support CUDA.
To figure out:

$ python3
>> import cv2
>> print(cv2.getBuildInformation())

Find CUDA is enabled.

Hi,
You may run this script to build OpenCV:
JEP/install_opencv4.5.0_Jetson.sh at master · AastaNV/JEP · GitHub

@MtHiker thanks for giving quick explanation.

As your configuration, CUDA is not enabled.

Yours and DaneLLL’s suggestions solved my issue. Thanks a lot to you. Wish I could select your both’s answers as solution.

One last question: Should I use cv::cuda::GpuMat Class to fully enhance the power of the GPU on image processing problems?

Back in the days, when using TX2 or TK1, I had heard that cv::Mat Class was modified for Jetsons to also use the GPU’s power. Was it true? If so, did things changed for Xavier?

Hi,

No, it is not true. cv::Mat is CPU buffer. For GPU buffer, please use cv::cuda::GpuMat to utilize CUDA filters.
