Abstract

A method and an arrangement for capturing an object by a movable sensor are provided. The method includes moving the sensor relative to the object and repeatedly ascertaining an instantaneous position of the sensor by a position measurement system, outputting the position to an evaluation device at a predetermined time point, repeatedly capturing the object by the sensor during a capturing time interval and outputting a measurement signal corresponding to the information captured during the capturing time interval. For at least one capturing time interval, a point in time of the capturing of the object is determined which lies within the capturing time interval, position values are ascertained and outputted at points in time which include the point in time of the capturing, and a position main value is ascertained based on the position values which approximates the position of the sensor at the point in time of the capturing.
