Python Onvif 控件

问题描述

我用python做了一切来操作ptz

我不确定焦点的输入/输出。 onvif首页，好像是焦点移动。

我不知道要获取和编辑什么值，所以我会上传它。

而且即使在调整光圈（光圈）值时，降低该值也可以，但是如果您做了+，则该值变化不大

在这种情况下，我认为

ptz = mycam.create_imaging_service()

如果您通过 ptz.Getoptions() 查看选项，则最大光圈值为 0，最小值为 -22。

media = mycam.create_media_service()

media_profile = media.GetVideoSources()[0]

这里，相机的图像设置是通过 GetVideoSources 加载的。从这个值，在 Imaging.Exposure

有当前光圈值的Iris，最大光圈值的MaxIris，最小光圈值的MinIris。

如果当前光圈值为-5，则MinIris取-22，但MaxIris取当前光圈值-5。

似乎即使每次加载时都带上更改后的值也不会更改，但是如果您知道如何修复它，请。
