A building surveying device comprising a base, an upper part supported on the base such that it can rotate about a rotation axis, a sighting unit with a laser source designed for emitting a laser beam, and a laser light detector and an evaluation and control unit. The building surveying device has a plumb point finding functionality which, after being triggered, runs automatically, at least in part, and in the course of which the alignment of the sighting unit is changed under automatic control by the evaluation and control unit with the aid of the first and/or the second rotary drive and as a function of a known, defined first spatial point in such a way that precisely one such second spatial point lying on an object surface is approached and marked by the laser beam, which lies on a vertical plumb line containing the first spatial point.

According to the invention, the construction measuring device has a functionality for modifying the orientation of the sighting unit in a manually controllable manner, within the framework of which the orientation of the sighting unit is dynamically modified by the first or second rotary drive, according to a current direction and a current distance from a defined central anchor display point to a currently marked display point. The respective current direction defines an orientation modifying direction and the respective current distance defines an orientation modifying speed for changing the orientation of the sighting unit.

Measuring appliance comprising a dynamic sighting functionality and associated method

A measuring appliance in which inputted or measured spatial points and a horizontal projection representation or spatial representation of at least some spatial points from the quantity of spatial points can be displayed, said points being at least partially connected by lines. The measuring appliance has a representation-changing functionality in the framework of which, according to a line selected on the user side from the lines displayed in a horizontal projection representation or a spatial representation, in an automatically controlled manner by means of the evaluation and control unit: a virtual surface is defined by the selected line and a direction provided as the vertical; a subset of spatial points is selected from the quantity of spatial points, lying inside a buffer zone surrounding the virtual surface in a defined manner; and a vertical projection representation of exclusively such spatial points pertaining to the subset is displayed on the display.

A surveying appliance for surveying targets has a targeting unit and a remote control unit for prompting changes in the orientation of the targeting unit, equipped with measurement functionality for determining a three-dimensional orientation of the remote control unit or for determining movements by the remote control unit. The surveying appliance also has an evaluation and control unit. The extent or speed of the changes in the orientation of the targeting unit can be scaled to corresponding changes in an orientation or speed of change of orientation of the remote control unit such that at least two targeting modes having different levels of transmission ratio are provided. The surveying appliance can be used with corresponding handheld, moving remote control units, computer program products for providing, controlling and performing a targeting functionality for the surveying appliance and methods for tracking and surveying targets using the surveying appliance.

A construction surveying device having a base, an upper part mounted on the base and can be rotated about an axis of rotation, a sighting unit having a laser source which is designed to emit a laser beam and a laser light detector, and an evaluation and control unit, a first rotary drive and a second rotary drive enable the upper part and the sighting unit to be driven and aligned, a spatial alignment of the sighting unit with respect to the base can be detected using two goniometers, and coordinates for space points can be determined using the evaluation and control unit, the construction surveying device has a horizontal line projection functionality which, at least sometimes, takes place automatically after triggering and is intended to measure and mark space points along a horizontal line, running in a horizontal plane, on an arbitrarily shaped surface.

Device for measuring and marking space points along horizontally running contour lines

A two-sided reflector for the reflection of a diffraction-limited optical beam bundle is embodied such that a planar first and second reflection element such as, for example, a reflection film and a cat's eye reflector are arranged with respect to a reference axis of the reflector in such a way that an absolute addition constant of zero results from the targeted choice of the properties of the first and second reflection element and the arrangement thereof with respect to the reference axis for a distance measurement. The distance measurement therefore essentially corresponds to a distance measurement on a natural surface. The distance measurement can therefore be referred directly to the reference axis without additional correction.
