opencv - OpenCV camera properties dialog

Question

A few weeks ago I saw on the internet that you could display a small dialog/ menu with a few properties of the camera. In this menu the user can change the contrast, brightness...but I can not find it anymore. Does somebody know the code to get this dialog?

Thank you in advance!

Answer 1

CV_CAP_PROP_SETTINGS使用任何值 设置属性。

cv::VideoCapture cap(0); 
cap.set(CV_CAP_PROP_SETTINGS, 0); //opens camera properties dialog

Answer 2

OpenCV 不提供此功能。不同的相机制造商有不同的 API 用于访问和更改相机参数。没有标准的方法可以做到这一点。因此，您可以尝试使用其 API 访问您的相机设置，然后您可以编写自己的 GUI 对话窗口（例如，使用QT 库）来查看/更改参数。
