Patent number: 9497383Abstract: A geodetic surveying device has a sighting unit pivotable about two axes. The sighting unit defines a target direction in a coordinate system and has a camera for capturing a camera image substantially in the target direction. The device can display object data that is stored in a database with a respective position reference indicating a position in the coordinate system. The device includes a graphical output unit that displays the camera image and the object data. The device has a filter functionality for the object data, with dynamic filtering based on the current range of view and static filtering based on a user selectable or specifiable selection criterion. The filtered object data is displayed on the output unit with markings representing the object data conjointly with the camera image. The markings are displayed at a respective point in the camera image referenced by the position reference.Type: GrantFiled: September 14, 2012Date of Patent: November 15, 2016Assignee: LEICA GEOSYSTEMS AGInventor: Werner Lienhart

Patent number: 9341473Abstract: A survey system including a target unit that has a survey stick having a high-precision localizable target and a hand-held remote control unit. The remote control unit has an electronic graphical display and can be mounted on a holder on the survey stick such that the remote control unit is in a fixed position relative to the target fitted to the survey stick. The remote control comprises a camera for taking a camera image in a defined shooting direction. In addition, an image processing and evaluation unit with a data link to the position-finding unit and to the camera is provided which, from knowledge of the fixed relative position and of a defined shooting direction and also on the basis of the determined target position, can spatially relate image data from the camera to the targets in the coordinate system.Type: GrantFiled: August 17, 2011Date of Patent: May 17, 2016Assignee: LEICA GEOSYSTEMS AGInventors: Hans-Martin Zogg, Werner Lienhart, Daniel Nindl, Norbert Kotzur

Patent number: 9046361Abstract: Target point recognition method including emitting electromagnetic radiation to illuminate targets, moving the scanning beam within a predetermined angular range in order to scan the surveying environment, detecting reflections of the electromagnetic radiation on the targets, wherein the targets are defining the target points, and determining the angle to the target points. The method further including a capturing procedure with capturing an overall image of the surveying environment, wherein the overall image comprises at least one single image taken by the camera, and determining target points and their angle on the overall image by image processing by matching targets with one or more predetermined search criteria, storing the target points together with their angle a data base, and displaying the overall image together with marks for indicating a position of the target points detected within the scanning procedure and the capturing procedure in the overall image.Type: GrantFiled: July 7, 2011Date of Patent: June 2, 2015Assignee: LEICA GEOSYTEMS AGInventors: Daniel Nindl, Hans-Martin Zogg, Werner Lienhart, Norbert Kotzur

Patent number: 9007573Abstract: Automated autocollimation provides alignment of a telescope of a surveying instrument. The telescope defines an optical axis perpendicular to a reflective surface of an autocollimation target, such as a coated plane mirror. Alignment is performed by a method that includes aligning the telescope with the autocollimation target and illuminating a reticle in the telescope. The telescope is focused on infinite. The autocollimation target and the illuminated reticle reflected by the reflective surface, or the illuminated reticle, are acquired using an image acquisition device in the telescope or a second telescope. The reticle center in the image is determined. The horizontal and vertical distances of the reticle center are determined from the optical axis of the telescope in the image. The horizontal and vertical distances of the reticle center are converted into horizontal and vertical aberration angles of the current alignment of the telescope from the autocollimation alignment of the telescope.Type: GrantFiled: December 2, 2011Date of Patent: April 14, 2015Assignee: Leica Geosystems AGInventors: Werner Lienhart, Daniel Nindl

MEASURING DEVICE THAT CAN BE OPERATED WITHOUT CONTACT AND CONTROL METHOD FOR SUCH A MEASURING DEVICE
Publication number: 20140226002Abstract: A geodetic measuring instrument for determining the position of a target point includes a sighting apparatus that can be pivoted with respect to a base of the measuring instrument to change the orientation of the sighting apparatus. The geodetic measuring instrument has at least one objective unit defining an optical target axis and has angle measurement functionality for precisely detecting the orientation of the target axis. Evaluating means store to and control the orientation of the sighting apparatus. An eye image recording unit records eye images of an eye of a user. The evaluating means perform automatic sighting functionality regardless of viewing direction in such a way that the following occurs automatically after the function has started: at least one eye image is recorded, a viewing direction of the user eye is determined, or eye information suitable for deriving a viewing direction of the user eye is determined.Type: ApplicationFiled: July 20, 2012Publication date: August 14, 2014Applicant: LEICA GEOSYSTEMS AGInventors: Bernhard Metzler, Stefan Sieber, Werner Lienhart, Hans-Martin Zogg -
