ifm3dpy.device.O3R

class ifm3dpy.device.O3R

Bases: Device

Class for managing an instance of an O3R Camera

__init__(self: ifm3dpy.device.O3R, ip: str = '192.168.0.69', xmlrpc_port: int = 80) → None

Constructor

Parameters

• ip (string, optional) – The ip address of the camera. Defaults to 192.168.0.69.

• xmlrpc_port (uint, optional) – The tcp port the sensor’s XMLRPC server is listening on. Defaults to port 80.

property name

check_minimum_firmware_version(self: ifm3dpy.device.Device, major: int, minor: int, patch: int) → bool

Checks for a minimum ifm camera software version

Parameters

• minor (int) – Minor Version of software

property name

device_parameter(self: ifm3dpy.device.Device, key: str) → str

Convenience accessor for extracting a device parameter

No edit session is created on the camera

Parameters

key (str) – Name of the parameter to extract

Returns

Value of the requested parameter

Return type

str

Raises

RuntimeError –

device_type(self: ifm3dpy.device.Device, use_cached: bool = True) → str

Obtains the device type of the connected camera.

This is a convenience function for extracting out the device type of the connected camera. The primary intention of this function is for internal usage (i.e., to trigger conditional logic based on the model hardware we are talking to) however, it will likely be useful in application-level logic as well, so, it is available in the public interface.

Parameters

use_cached (bool) – If set to true, a cached lookup of the device type will be used as the return value. If false, it will make a network call to the camera to get the “real” device type. The only reason for setting this to false would be if you expect over the lifetime of your camera instance that you will swap out (for example) an O3D for an O3X (or vice versa) – literally, swapping out the network cables while an object instance is still alive. If that is not something you are worried about, leaving this set to true should result in a signficant performance increase.

Returns

Type of device connected

Return type

str

factory_reset(self: ifm3dpy.device.O3R, keep_network_settings: bool) → None

Sets the camera configuration back to the state in which it shipped from the ifm factory.

Parameters

keep_network_settings (bool) – A bool indicating wether to keep the current network settings

firmware_version(self: ifm3dpy.device.Device) → ifm3dpy.device.SemVer

Version of firmware installed on device

Returns

Firmware version

Return type

SemVer

force_trigger(self: ifm3dpy.device.Device) → None

Sends a S/W trigger to the camera over XMLRPC.

The O3X does not S/W trigger over PCIC, so, this function has been developed specficially for it. For the O3D, this is a NOOP.

from_json(self: ifm3dpy.device.Device, json: dict) → None

Configures the camera based on the parameter values of the passed in JSON. This function is _the_ way to tune the camera/application/imager/etc. parameters.

Parameters

json (dict) – A json object encoding a camera configuration to apply to the hardware.

Raises

RuntimeError – If this raises an exception, you are encouraged to check the log file as a best effort is made to be as descriptive as possible as to the specific error that has occured.

get(self: ifm3dpy.device.O3R, path: List[str] = []) → dict

Returns the configuration formatted as JSON based on a path. If the path is empty, returns the whole configuration.

Returns

The JSON configuration for the list of object path fragments

Return type

dict

get_diagnostic(self: ifm3dpy.device.O3R) → dict

Returns the content of the diagnostic memory formatted in JSON
