Method for starting up a field device in a simplified manner

A method for starting-up a field device of automation technology mounted on a component at a measuring location, the method comprising:

• providing a service unit including a display unit and a camera;
• identifying the field device using the service unit;
• ascertaining parameters of the field device to be set based on the identifying of the field device;
• registering geometry data of at least a part of the component using the camera;
• registering a reference geometry using the camera, wherein the reference geometry has a defined length in at least one dimension;
• creating a three-dimensional, polygonal network based on the reference geometry
• analyzing the registered geometry data and deriving at least one parameter value for at least one of the parameters to be set, wherein the deriving of the at least one parameter value is based on the analyzed registered geometry;
• confirming the at least one parameter value;
• and
• transferring the confirmed at least one parameter value into the field device and storing the confirmed at least one parameter value in the field device.
