Measuring appliance comprising a dynamic sighting functionality and associated method

A measuring appliance for measuring spatial points of surfaces of a construction including interiors of buildings comprising:

• a base;
• a sighting unit, which is rotatable and pivotable relative to the base and provides distance measuring functionality, having a laser source designed to emit a laser beam in the direction of an aiming axis, and a laser light detector and also having an integrated digital camera aligned in the direction of the aiming axis;
• an evaluation and control unit;
• a display for representing an image of the camera;
• input means for marking display points on the display;
• a first and a second rotary drive make the sighting unit drivable and alignable;
• a spatial alignment of the sighting unit relative to the base is detectable by means of two goniometers;
• the evaluation and control unit is connected to the laser source, the laser light detector and also the goniometers in order to assign a detected distance to a corresponding alignment and thus to determine coordinates for spatial points, and is also connected to the camera;
• wherein the measuring appliance is equipped with a functionality for changing the alignment of the sighting unit in a manually controllable manner, in the context of which dynamically in a manner dependent on a constantly determined current direction and a constantly determined current distance from a defined central anchor display point to a currently marked display point, the alignment of the sighting unit is changed by the first and/or second rotary drive;
• and
• wherein the respective current direction predefines an alignment change direction and the respective current distance predefines an alignment change speed for changing the alignment of the sighting unit.

A method for the manually controlled alignment of a sighting unit of a measuring appliance on the basis of marking display points on a display, wherein the measuring appliance comprises:

• a base;
• sighting unit, which is rotatable and pivotable relative to the base and provides distance measuring functionality, having a laser source designed to emit a laser beam in the direction of an aiming axis, and a laser light detector and also having an integrated digital camera aligned in the direction of the aiming axis;
• an evaluation and control unit;
• the display for representing an image of the camera;
• input means for marking the display points;
• a first and a second rotary drive make the sighting unit drivable and alignable;
• a spatial alignment of the sighting unit relative to the base is detectable by means of two goniometers;
• the evaluation and control unit is connected to the laser source, the laser light detector and also the goniometers in order to assign a detected distance to a corresponding alignment and thus to determine coordinates for spatial points, and is also connected to the camera;
• wherein constantly a current direction and a current distance from a defined central anchor display point to a currently marked display point are determined and the alignment of the sighting unit is changed dynamically in a manner dependent on the respective current direction and the respective current distance by the first and/or second rotary drive;
• and
• the respective current direction predefines an alignment change direction and the respective current distance predefines an alignment change speed for changing the alignment of the sighting unit.
