I want to use Pylonsrc in Python #77

Closed jooyeop closed 7 months ago

jooyeop commented 7 months ago

I'm using 2 basler, and I'd like to use both in one Python script. I'm curious about the parameters that can operate both cameras. If you connect both cameras and use the code below, you will get an error.

It only works when one camera is connected, but I'm curious about the parameters available on Python.

cap_pylon = cv2.VideoCapture("pylonsrc " "cam::PixelFormat=YUV422_YUYV_Packed " "cam::GainRaw=150 ! " "video/x-raw,width=1920,height=1200,format=YUY2 ! " "videoconvert ! " "video/x-raw,format=BGR ! " "appsink", cv2.CAP_GSTREAMER)

When using multiple cameras, you have to select the cameras. See about selecting here: https://github.com/basler/gst-plugin-pylon#camera-selection

I looked at it and used it on Python as below, but I couldn't use it.

cap_pylon = cv2.VideoCapture("pylonsrc device-index = number or device-serial-number = 'number' " "cam::PixelFormat=YUV422_YUYV_Packed " "cam::GainRaw=150 ! " "video/x-raw,width=1920,height=1200,format=YUY2 ! " "videoconvert ! " "video/x-raw,format=BGR ! " "appsink", cv2.CAP_GSTREAMER)

Five lines later there are examples: https://github.com/basler/gst-plugin-pylon#examples

E.g. First camera device-index=0 Second camera device-index=1 ...

다섯 줄 뒤에는 예제가 있습니다: https://github.com/basler/gst-plugin-pylon#examples

예: 첫 번째 카메라 device-index=0 두 번째 카메라 device-index=1 ...

cap_pylon = cv2.VideoCapture("pylonsrc device-index = 0 " "cam::PixelFormat=YUV422_YUYV_Packed " "cam::GainRaw=150 ! " "video/x-raw,width=1920,height=1200,format=YUY2 ! " "videoconvert ! " "video/x-raw,format=BGR ! " "appsink", cv2.CAP_GSTREAMER)

cap_pylon2 = cv2.VideoCapture("pylonsrc device-index = 1" "cam::PixelFormat=YUV422_YUYV_Packed " "cam::GainRaw=150 ! " "video/x-raw,width=1920,height=1200,format=YUY2 ! " "videoconvert ! " "video/x-raw,format=BGR ! " "appsink", cv2.CAP_GSTREAMER)

Should I write it like above and use it? There was an error a few days ago, but I'll try it again and ask.
