如何获取 OpenCV 的 USB 网络摄像头 属性 ID

How do I get usb webcam property IDs for OpenCV

我想将焦点锁定在我与 OpenCV 一起使用的 USB 网络摄像头上,但如何找到该网络摄像头的 属性 ID 号以便我可以设置它们。

我用过

vid = cv2.VideoCapture(2)
for i in range(64):
        
    print(f'ID {i} = {vid.get(i)}')

获取所有值,但我不知道哪个 bool 值是哪个。

驱动程序:Realtek Semiconductor Corp. 全高清 1080P 网络摄像头

C/C++ 文档 Flags for video I/Oenum cv::VideoCaptureProperties 部分,您可以找到值和名称,即

cv::CAP_PROP_FRAME_WIDTH =3,

对于python,它将是

cv2.CAP_PROP_FRAME_WIDTH = 3 

你可以用什么检查

print(cv2.CAP_PROP_FRAME_WIDTH)

在同一页面但稍低一点您可以看到 VideoCaptureProperties 和信息

VideoCapture generic properties identifier.

Reading / writing properties involves many layers. 
Some unexpected result might happens along this chain. 
Effective behaviour depends from device hardware, driver and API Backend. 

这可能意味着这些值对所有设备都是通用的,但某些设备或 codecs/drivers 可能没有某些值。

还有 link Additional flags for video I/O API backends 的属性仅适用于某些 codes/drivers。


在第Video I/O with OpenCV Overview页您还可以看到

Each backend supports devices properties (cv::VideoCaptureProperties) in a different way 
or might not support any property at all.

顺便说一句:

Python 的名字(但没有数字)也在旧版本 2.4 的文档中: VideoCapture::get


在更旧的版本中 Python 使用的名称略有不同 - 即

cv2.cv.CV_CAP_PROP_FRAME_WIDTH
cv2.cv.CV_CAP_PROP_FRAME_HEIGHT

编辑:

我制作了一个程序来列出所有按值排序的属性。

如果您跳过 sorted(),则会按名称排序。

import cv2

properties = []

for name in dir(cv2):
    if name.startswith('CAP_PROP'):
        value = getattr(cv2, name)
        properties.append((value, name))
        
# it will sort by values
# originally it is sorted by names
properties = sorted(properties)

for value, name in properties:
    print(f' {value:5} | cv2.{name}')
        

按值排序:
