Surveying appliance and method having a targeting functionality which is based on the orientation of a remote control unit and is scalable

A surveying appliance for surveying target points, comprising:

• a sensor unit that includes:
• a laser source;
• a distance determining detector;
• a sighting unit that is mounted so as to be able to swivel about a swivel axis on an upper part that is mounted so as to be able to rotate about an axis of rotation on a base;
• and
• a first and a second rotary drive that render the upper part and the sighting unit drivable and orientable;
• a remote control unit for prompting changes to the orientation of the sighting unit and equipped with a measuring functionality for determining a spatial orientation of the remote control unit and/or for determining movements by the remote control unit;
• and
• an evaluation and control unit;
• wherein,
• a spatial orientation of the sighting unit relative to the base can be detected by means of two goniometers;
• the evaluation and control unit is connected to the laser source, the distance determining detector and the goniometers to associate a detected distance with a corresponding orientation and hence to determine coordinates for target points;
• and
• the changes in the orientation of the sighting unit in an azimuthal and/or elevational direction can have their extent and/or their speed scaled to corresponding changes in an azimuthal and/or elevational orientation or speed of change of orientation of the remote control unit such that at least two sighting modes that differ from one another at least in terms of a transmission ratio level are provided.

A method for surveying target points using a surveying appliance having a sensor unit that includes:

• a laser source;
• a distance determining detector;
• a sighting unit that is mounted for swiveling about a swivel axis on an upper part that is mounted for rotation about an axis of rotation on a base;
• and
• a first rotary drive and a second rotary drive that render the upper part and the sighting unit drivable and orientable;
• a remote control unit that is configured to prompt changes to the orientation of the sighting unit and has measuring functionality for determining a spatial orientation of the remote control unit and/or for determining movements by the remote control unit;
• and
• an evaluation and control unit, wherein:
• a spatial orientation of the sighting unit relative to the base can be detected using two goniometers;
• and
• the evaluation and control unit is connected to the laser source, the distance determining detector and the goniometers to associate a detected distance with a corresponding orientation and hence to determine coordinates for spatial points;
• the method comprising:
• determining the spatial orientation of the remote control unit and/or changes in the spatial orientation of the remote control unit using a measuring functionality of the remote control unit;
• prompting changes in the orientation of the sighting unit in line with the spatial orientation and/or the changes in the spatial orientation of the remote control unit;
• and
• scaling the transmission ratio between the changes in the orientation of the remote control unit and the changes in the orientation of the sighting unit in an azimuthal and/or elevational direction, such that at least two sighting modes that differ from one another at least in terms of a transmission ratio level are provided.
