使用OpenGL绘制OpenCV [英] Drawing in OpenCV with OpenGL

问题描述

OpenCV库在编译时支持GPU和OpenGL，允许使用OpenGL显示图像。例如， video_reader.cpp （位于gpu示例中）使用OpenGL直接从 cv :: gpu :: GpuMat 。

OpenCV library, when compiled with GPU and OpenGL support, allows for displaying images with OpenGL. For example, video_reader.cpp (located in gpu samples) uses OpenGL to render display graphics directly from cv::gpu::GpuMat.

cv::gpu::GpuMat d_frame;
namedWindow("OpenGL", WINDOW_OPENGL);
cv::gpu::VideoReader_GPU d_reader(fname);
d_reader.dumpFormat(std::cout);
if (!d_reader.read(d_frame))
    break;
cv::imshow("GPU", d_frame);

这是一个非常有用的功能。但是，在在线文档中没有记录。例如，对于 namedWindow 标志 WINDOW_OPENGL 未列在文档中。在哪里可以找到OpenCV相关功能的文档？

This is a very useful feature. However, it is not documented in the documentation on-line. For example, for namedWindow the flag WINDOW_OPENGL is not listed in the docs. Where can I find the documentation for OpenGL -related functionality of OpenCV?

推荐答案

文档不是很完整的2.4.5。我认为没有任何文档比您在 http://docs.opencv.org 上看到的文档更多。

The documentation is not very complete for 2.4.5. I don't think there is any more documentation than what you see on http://docs.opencv.org.

有较旧的文档，例如 http： //opencv.willowgarage.com/documentation/cpp/ for 2.1，但我没有找到它所需要的标志的文档。

There are older documentation, such as http://opencv.willowgarage.com/documentation/cpp/ for 2.1, but I didn't find it having the documentation for the flag that you wanted.
