I am using latest Jetpack 4.2.1 and compiled opencv with opengl.
Opencv is compiled without any error and following were the parameters
cmake -D CMAKE_BUILD_TYPE=RELEASE -D CMAKE_INSTALL_PREFIX=/usr/local
-D OPENCV_EXTRA_MODULES_PATH=…/…/opencv3.4/opencv_contrib-3.4.1/modules
-D WITH_CUDA=ON -D CUDA_ARCH_BIN=“6.2” -D CUDA_ARCH_PTX=“”
-D WITH_CUBLAS=ON -D ENABLE_FAST_MATH=ON -D CUDA_FAST_MATH=ON
-D ENABLE_NEON=ON -D WITH_LIBV4L=ON -D BUILD_TESTS=OFF
-D BUILD_PERF_TESTS=OFF -D BUILD_EXAMPLES=OFF
-D WITH_QT=ON -D WITH_OPENGL=ON …
I made a simple test to check opengl. The mat blow display blue correctly while opengl window stays black. I am not able to resolve it although there are no compilation or run time error.
int main(int argc, char* argv)
{
Mat testImage(480, 640, CV_8UC3, cv::Scalar(0xBB));
cv::namedWindow(“OpenGL”, cv::WINDOW_OPENGL | cv::WINDOW_AUTOSIZE);
cuda::GpuMat testImageGpu;
testImageGpu.upload(testImage);
cv::imshow("OpenGL", testImageGpu);
cv::imshow("Window", testImage);
cv::waitKey(5000);
return 0;
}
