Hello World:
CVB PYTHON
import osimport cvb
with cvb.DeviceFactory.open(os.path.join(cvb.install_path(), "drivers", "CVMock.vin") as device:stream = device.streamstream.start()
for i in range(10):image, status = stream.wait()if status == cvb.WaitStatus.Ok:
print("Acquired image: " + str(i))
stream.abort()

EXAMPLE TASK
Live display
Works with any GenICam device
Responsive / designable UI
A STEMMER IMAGING PRODUCT
CVB DISPLAY
How To?
Multithreaded
Generic HW handling
Separate UI from Logic (MV… whatever)
