Patent ID: 8539686

Claim:
A leveling device comprising: a targeting device, which defines an alignment axis and which can be aligned with a measuring rod for the purpose of determining height; an imaging system, which is spatially separated from the targeting device and comprises an imaging objective, to which an objective principal plane is assigned; and a detector, comprising a recording surface lying in an image plane, wherein a field of view of the imaging system is defined by the imaging objective and the detector as that maximum angle range within which points can be detected by the imaging objective by means of the recording surface of the detector, and an evaluation device, which is connected to the detector, wherein: height information of the measuring rod at the height of the alignment axis can be provided as a measurement height by the evaluation device using the detector information; the imaging objective and the detector are embodied and arranged relative to one another and to an object plane containing the alignment axis in such a way that all points of the object plane which lie within the field of view are simultaneously imaged sharply on the recording surface of the detector; and the objective principal plane, the image plane and the object plane are aligned relative to one another in a manner meeting the Scheimpflug condition.
