Can't connect with Smartek Giganetix GC1291MP camera

Python
1

Good day.
I am new with OpenCV
I want to use Smartek Giganetix GC1291MP camera for my project, but don’t know how to setup it.

I use code below, but it returns isOpened = False
I assume, I didn’t setup connection properly, but I can’t find any information how to establish a connection with none webcam.

Could someone help me?

def connecting_to_cam():
    device = cv2.CAP_GIGANETIX
    cap = cv2.VideoCapture(device)

    if cap.isOpened() is False:
        print("Can't open camera!")
        quit()
    
    width = int(cap.get(cv2.CAP_PROP_FRAME_WIDTH))
    height = int(cap.get(cv2.CAP_PROP_FRAME_HEIGHT))
    frames = int(cap.get(cv2.CAP_PROP_FRAME_COUNT))

    writer = cv2.VideoWriter("Video/test_video1.mp4", cv2.VideoWriter_fourcc(*'DVIX'), 25, (width, height))

    while True:
        ret, frame = cap.read()

        writer.write(frame)

        #gray = cv2.cvtColor(frame, cv2.COLOR_BGR2GRAY)
        cv2.imshow('frame', frame)

        if cv2.waitKey(1) & 0xFF == ord('q'):
            break

    cap.release()
    writer.release()
    cv2.destroyAllWindows()

please check cv2.getBuildInformation() (the VideoIO section),
to see if your cv2 has builtin support for this
(most likely - not so, you need to build it locally, with the resp. GigE sdk installed)

Thank you.

My VideoIO section

I guess I have not it, but how I can build it locally? I’ve already installed GigE SDK.

doesnt that already have it’s own python bindings ?

otherwise, you’'d have to build from github src
build instructions are unfortunately slightly outdated and overcomplicated (sigh…) well the gist of it is:

  • get source code (zip will do), cmake, and a c++ compiler (VS or mingw)
  • make a build folder and cd into it
  • run cmake-gui, make sure it finds compiler,python and the sdk
  • build the INSTALL project(VS) or run mingw32-make install in the build folder

it’s probably a good idea, to report back the cmake output here, as most problems happen there !
