Method for providing information about an object (5) using an unmanned aerial vehicle with a data acquisition unit, comprising determining positional data with reference to the object (5), the positional data being referenced to a measuring coordinate system, providing a digital template (11) regarding the object (5), the template (11) at least partly representing the object (5) in coarse manner, and referencing the template (11) with the positional data so that the template (11) corresponds as to its spatial parameters to the object in the measuring coordinate system. Moreover, a spatial position of at least one data acquisition point (12) or section is related to the object (5) is derived based on at least the positional data and/or the template (11), the unmanned aerial vehicle is controlled in a manner such that it approaches the at least one data acquisition point (12) or section and object information is acquired as to at least a part of the object (5) according to the at least one data acquisition point (12) or section by triggering the data acquisition unit depending on fulfilling a defined distance criterion, the distance criterion defining a spatial relation between an actual position of the unmanned aerial vehicle and the at least one data acquisition point (12) or section.

Method for compensating a force at a probe element of a probing unit (16), the probing unit (16) being attached to and moved along a defined moving path with a number of moving points by a coordinate measuring machine for approaching a measuring point at an object, wherein the probing unit (16) comprises an actuator (21) which is arranged and designed in such manner that a force is applicable to the probe element with respect to at least one actuating direction in variable and defined manner, the force depending on an applied actuating signal. Movement information about an expected movement of the probing unit (16) is received, the movement information provides information about an expected displacement behaviour of the probe element relative to the probing unit due to induced forces emerging by moving the probing unit (16). At least one particular expected displacement behaviour of the probe element is derived for at least one particular moving point based on the movement information and the actuating signal is determined for the at least one particular moving point based on the at least one particular expected displacement behaviour, the actuating signal provides applying a defined counterforce to the probe element by the actuator (21) as to the expected displacement behaviour at the particular moving point.
