I try to run continuous_move.py,has some problem ,please help me. runtime enviorment : python3.6

i got the same error , please let me know when you fix it

I can't find a solution，just using python2.7 is ok@chenmaolin88

[chenmaolin88]

@Jeffer-hua i found a solution , the problem is : the "space" value of the response is not correct, add the following code below line 96 of the examples/continuous_move.py

        moverequest.Velocity = ptz.GetStatus({'ProfileToken': media_profile.token}).Position
        moverequest.Velocity.PanTilt.space = ptz_configuration_options.Spaces.ContinuousPanTiltVelocitySpace[0].URI
        moverequest.Velocity.Zoom.space = ptz_configuration_options.Spaces.ContinuousZoomVelocitySpace[0].URI

this can fix the problem , at least work with my camera , my camera is hikvision DS-2DC7223IW-A

[hua1024]

thanks，it worked，How can I control the camera to rotate to a fixed position @chenmaolin88

[chenmaolin88]

as far as i know, you need to change the operation from continuousMove to AbsoluteMove, follow the ptz.wsdl file , modify the example code above. i am working with the relativeMove operation, once I finish that , I will give you the code ,you can refer to that.

[hua1024]

yes，i am change to AbsouteMove , but the range of x or y is -1 to 1 which in onvif protocol，i can't change to hikvision pcoordinate system.@chenmaolin88

[chenmaolin88]

@Jeffer-hua you can rotate you camera to the specific coordingates with the official software, then you can get the current coordintes in onvif protocol by the following code: ptz.GetStatus({'ProfileToken': media_profile.token}).Position that means hikvision can translate it for you , you don't need hikvision's private coordinate system

@chenmaolin88 thank you very much for your good suggestions
