用于在ubuntu12.04中使用OpenCV查看图像中的值的GUI [英] GUI to view values in image using OpenCV in ubuntu12.04

问题描述

是否可以同时显示图像和像素，基于鼠标指针位置的坐标值？

Is it possible to simultaneously display an image and the pixel,coordinate values based on the mouse pointer positions?

我在MATLAB中询问OpenCV等效的imview函数。

I am asking an OpenCV equivalent of imview function in MATLAB.

推荐答案

我曾经使用旧代码单独使用OpenCV尝试执行此操作时出现了一些问题。在这一点上，我不确定我是否遗漏了某些内容，或者它是否是OpenCV中的错误。我会进一步调查。

I had a few problems trying to do this with OpenCV alone using an old code I wrote a while back. At this point I'm not sure if I missed something or if it's a bug in OpenCV. I'll investigate this further.

但我分享了一个简短，自我在我的存储库中包含，更正（可编辑），示例，检查 cvImage 。它用Qt和OpenCV 用 C ++编写。这是一个Qt应用程序使用OpenCV加载图像并将RGB值显示为Qt窗口的标题。

But I shared a short, self contained, correct (compilable), example at my repository, check cvImage. It's written in C++ with Qt and OpenCV. It's a Qt application that loads an image with OpenCV and displays the RGB values as the title of the Qt window.

移动鼠标并放置光标在您感兴趣的像素之上，看它的RGB值。

Move the mouse around and place the cursor on top of the pixel that you are interested at to see it's RGB value.
