A coordinate measuring machine (1,2) for determining at least one spatial coordinate of a measurement point of an object (15) to be measured, comprising a measuring volume representing a particular volume as to a design of the coordinate measuring machine (1,2), inside which at least one spatial coordinate of the measurement point is determinable, characterised by a first camera (50-52), wherein the camera (50-52) is adapted to be directed to the measuring volume for providing at least a first image of at least a first part of the measuring volume, and a controller, adapted to control a drive mechanism on the basis of image data derived from the at least first image and adapted for execution of a measuring mode for precisely determining the at least one spatial coordinate of the object to be measured, on execution of which a probe head (13) is guided relatively to the object (15) on a predefined measurement path and the at least one spatial coordinate of the measurement point of the object is derived from a measurement to the measurement point, and an object-determination functionality, on execution of which surface data related to a surface of a body inside the measuring volume is derived from at least the first image by image processing as the image data and controlling information is derived depending on the surface data for controlling the guidance of the probe head (13), wherein the object-determination functionality is executed in advance of the measuring mode and the controlling information is provided for execution of the measuring mode.
