Service camera.onvif_ptz: add Speed option

Veda82 · January 8, 2019, 12:46pm

Onvif Camera component supports Pan, Tilt and Zoom through the camera.onvif_ptz service:

However, onvif standard has also the option to control the Speed of the Pan and tilt operation (see here, under Velocity):

https://www.onvif.org/ver20/ptz/wsdl/ptz.wsdl

onvif-py3 library seems to support this:

github.com

rambo/onvif-py3/blob/py3/examples/continuous_move.py

from time import sleep

from onvif import ONVIFCamera

XMAX = 1
XMIN = -1
YMAX = 1
YMIN = -1


def perform_move(ptz, request, timeout):
    # Start continuous move
    ptz.ContinuousMove(request)
    # Wait a certain time
    sleep(timeout)
    # Stop continuous move
    ptz.Stop({'ProfileToken': request.ProfileToken})


def move_up(ptz, request, timeout=1):

Particularly:

def move_up(ptz, request, timeout=1):
print(‘move up…’)
request.Velocity.PanTilt._x = 0
request.Velocity.PanTilt._y = YMAX
perform_move(ptz, request, timeout

It would be nice to have an additional option in the camera.onvif_ptz service to be able to control the speed.
