Method and opto-electronic measuring device for measuring of an object's surface with a measuring rate of at least one thousand object points per second. Using a high-speed autofocus optical module comprising at least one variable focal length lens or reconfigurable optical phase plate having a response time of under 1 ms, situated in an emitting beam path, there is a real-time focus adaption of the measurement beam within a single object point measurement period.

Scanning device with point-to-point focusing

A method and device for displaying desired positions in a live image of a construction site. The method mat include recording at least one position-referenced image of the construction site; linking at least one desired position to the position-referenced image; storing the position-referenced image together with desired position linkage in an electronic memory; recording a live image of the construction site, in particular in the form of a video, wherein the live image and the position-referenced image at least partially represent an identical detail of the construction site; retrieving the stored position-referenced image from the memory; fitting the position-referenced image with the live image, so that the desired position linked to the position-referenced image can be overlaid in a position-faithful manner on the live image; and position-faithful display of the desired position as a graphic marking in the live image.

A measuring device can have a scanning functionality for optical surveying of an environment, wherein the measuring device has a sensor comprising an assembly of microcells as a receiving surface and direction-dependent active sections of the receiver are defined depending on the transmission direction of the transmitted radiation, in order to adapt the active receiver surface to a varying imaging position of the received radiation.

Measuring device having scanning functionality and settable receiving ranges of the receiver

A total station or a theodolite includes scanning functionality for optical surveying of an environment, in which the total station or the theodolite is configured such that direction-dependent active acquisition regions of the receiver are defined depending on the transmission direction of the transmitted radiation to adapt the receiver surface mechanically and/or electronically to a varying imaging position of the received radiation on the overall detector surface.

A measuring system comprising a measuring apparatus including a first portion comprising a first casing, a first length measuring body, a first length measuring device, and a first reference point. A first end of the first length measuring body is attached to the first casing, a second end extends away from the first casing, the first length measuring device measures a first distance between the second end and the first reference point; a second portion comprising a second casing, a second length measuring body, a second length measuring device, and a second reference point. A first end of the second length measuring body is attached to the second casing, a second end extends away from the second casing, the second length measuring device measures a second distance between the second end and the second reference point. The first and second portion are coupled and rotate relative to each other.

Measuring system

An opto-electro-mechanical system for manipulating optical radiation comprising a rotationally or translationally movable element, wherein the element is itself an optical element or comprises an optical element. Furthermore the system comprises a stator for the movable element having a recess enabling a deflection range, a flexible connection between the stator and the movable element providing a corresponding kinematically defined mobility, and an actuator for deflecting the movable element, wherein the stator is connected as one piece to the movable element, and the one-piece connection consists of silicate glass- and the recess is arranged around the movable element in such a way that the movable element is deflectable in accordance with the kinematically defined mobility with elastic deformation of the connection by means of the actuator.

Opto-electro-mechanical beam manipulation system

A surveying device including a base defining a base axis, a support structure rotatable around the base axis and defining a rotation axis, a light emitting unit emitting light and a light receiving unit for detecting reflected light. A rotation unit is mounted on the support structure for emitting and receiving light in defined directions, wherein the rotation unit comprises a rotation body rotatable around the rotation axis including a scanning mirror arranged tilted relative to the rotation axis. An imaging unit for capturing an image of a scanning region is provided. The imaging unit comprises a camera fixedly arranged on the support structure, the rotation body comprises at least one reflecting deflecting surface assigned to the camera. The imaging unit and the rotation body are arranged so that the field of view comprises a defined field angle around the rotation axis.

Surveying instrument for scanning an object and image acquisition of the object

Some embodiments of the invention relate to a rotation unit for a surveying device, in particular a laser scanner for optically scanning an environment and such a surveying device. The surveying device has a rotation unit having a rotation mirror, for deflecting an emission light beam and a reception light beam, and a rotation body implemented as a cylinder having a on a beveled, free end. The rotation body is implemented as a hollow cylinder having a cylinder bottom and a beveled cylinder wall on its free end. The hollow cylinder is connected coaxially with respect to its cylinder axis in a rotationally-fixed manner to a motor-driven shaft via the cylinder bottom. The rotation mirror is fastened in the region of its free end to the cylinder wall of the hollow cylinder so it is supported thereby.
