hardware trigger

[ypark137]

Hi, I have been having problems with Line 2 trigger. Line 2 trigger is working well on Vimba Viewer 2.0, but it doesn't take the trigger when using pymba. A code that is similar to this one was working before but it stopped working. I've tried restarting the camera and reinstalling pymba and vimba, and tried another computer also....My camera is GS1380. The liveview examples that comes with pymba are all working well.

from pymba import *
import cv2
import numpy as np

vimba = Vimba()

vimba.startup()

system = vimba.getSystem()
system.runFeatureCommand("GeVDiscoveryAllOnce")

cameraIds = vimba.getCameraIds()

camera = vimba.getCamera(cameraIds[0])

camera.openCamera()

camera.TriggerMode = 'On'
camera.TriggerSource = 'Line2'
camera.TriggerActivation = 'RisingEdge'
camera.PixelFormat = 'Mono8'
camera.TriggerSelector = 'FrameStart'
camera.AcquisitionMode = 'Continuous'

print 'TriggerMode:', camera.TriggerMode
print 'TriggerSource:', camera.TriggerSource
print 'TriggerActivation:', camera.TriggerActivation
print 'TriggerSelector:', camera.TriggerSelector

frame = camera.getFrame()

frame.announceFrame()

camera.startCapture()

frame.queueFrameCapture()

frame.waitFrameCapture(3000)

print 'frame 1 captured or timed out '

imgData1 = frame.getBufferByteData()

camera.endCapture()

data1_np = np.ndarray(buffer=imgData1,
                      dtype=np.uint8,
                      shape=(frame.height, frame.width))

rgb = cv2.cvtColor(data1_np, cv2.COLOR_BAYER_RG2RGB)

cv2.imwrite('testTrigger.png'.format(1), rgb)
camera.revokeAllFrames()
camera.closeCamera()
print 'frame is saved as png'

Does adding camera.runFeatureCommand('AcquisitionStart') right after frame.queueFrameCapture() and camera.runFeatureCommand('AcquisitionStop') after frame.waitFrameCapture(3000) help?

It works! Thanks!

Glad to hear it =)

Hi, since this was opened in 2016, can you provide an updated example? I noticed that the method names listed above have changed since 2016.

Thank you!
