Patent number: 11789126Abstract: A laser distance meter forming a handheld device comprising a housing, an electro-optical distance measurement unit arranged in the housing for ascertaining at least one measured distance between the laser distance meter and a target object in a measurement direction, and a camera having a field of view in the measurement direction. A deflection unit is disposed in the housing for the angular deflection of the measurement direction and an operating and input arrangement for operating at least the distance measurement unit and the camera. A control unit at the housing is configured to activate the distance measurement unit and the deflection unit such that a series of measured values of the measured distance are recorded in different deflections along a path of the deflection, and a subsequent selection of the measured distances from the series of measured values is carried out using the operating and input arrangement.Type: GrantFiled: September 11, 2019Date of Patent: October 17, 2023Assignee: LEICA GEOSYSTEMS AGInventor: Markus Hammerer

Patent number: 11402203Abstract: A sensor module for connection to a handheld rangefinder instrument and for providing sensor data for the rangefinder instrument includes an electronic interface for connection to an applicable interface of the rangefinder instrument, and at least one electronic sensor component for generating the sensor data. A system for handheld measurement of distances to a surface region of an object includes a sensor module of this kind and a handheld rangefinder instrument having a first laser rangefinder. When the interfaces are connected to one another, the sensor module is configured for transmitting the sensor data to the rangefinder instrument, and the interfaces are configured for transmitting electric power from the rangefinder instrument to the sensor module, in which the sensor module is configured to operate the at least one sensor component by means of the electric power transmitted by the rangefinder instrument.Type: GrantFiled: October 4, 2018Date of Patent: August 2, 2022Assignee: LEICA GEOSYSTEMS AGInventors: Thomas Bösch, Markus Hammerer

Publication number: 20220196403Abstract: A method comprises detecting at a plurality of light-receiver units, an impingement position of the light plane on a photo sensor that has a known relative position in relation to the surface, determining, for each light-receiver unit and based on the impingement position and the known relative position, a crossing position value of the light plane with respect to the surface, performing a combined analysis of the crossing position values from the plurality of light-receiver units to derive alignment information comprising the deviation of the alignment of the surface of the structure relative to the light plane, and displaying the alignment information to a user. The invention also relates to computer programme product, a light-receiver unit and a system comprising a plurality of light-receiver units for performing the method.Type: ApplicationFiled: December 21, 2021Publication date: June 23, 2022Applicant: LEICA GEOSYSTEMS AGInventors: Markus HAMMERER, Elvir MALKOC

Patent number: 6734952Abstract: In geodetic measuring systems and measuring devices (14) there exists a need to find and detect, rapidly and automatically, marker points to be measured that are provided with a marker (retro reflector) (2a). For the rapid detection, identification and determination of the horizontal angles of such a marker, even at greater distances, electromagnetic radiation in the form of a vertical fan (17) is transmitted by a transmitter unit (1) whose radiation is received, after reflection from the marker, by a receiving unit with a view field in the form of a vertical fan. By analyzing the signal strength and the apparent object size, a plausibility test and a reliable suppression of foreign or interference markers can be achieved. Such a marker searching device is marked by a selective analysis of specific characteristics of a marker detected. On the basis of the plausibility test, a rapid, certain and robust location of markers is possible.Type: GrantFiled: January 17, 2003Date of Patent: May 11, 2004Assignee: Leica Geosystems, AGInventors: Paul Benz, Markus Geser, Roland Graf, Bruno Pfiffner, Marcel Buerki, Marco Landert, Markus Hammerer, Jürg Hinderling, Günther Hanns, Gerhard Bayer
