摘要： The invention relates to a method and a device for detecting an object point (12) on an object (14) such as a work piece or a tool, by means of a sensor (16). In order to obtain an extremely precise measurement at a high measuring speed, a first detection of the object point (12) is carried out by displacing the sensor (16) in the direction of the object (14) at a first speed V1 and a second detection of the object point (12) is carried out by moving the sensor (16) away from the object (14) at a second speed V2, the actual measured value being determined by the second object point detection.
