Patent number: 11703328Abstract: A surveying pole system comprising a surveying pole including two telescopic sections for providing length adjustability. At a first end of the surveying pole, a pointing tip is disposed for positioning on a target point of the environment. At a second end, a length reference point is disposed. The surveying pole also includes a locking mechanism for locking the length adjustability in respective lock-in positions. Each of the lock-in positions provides a corresponding distance between the pointing tip and the length reference point. A plurality of coded identifiers have a predetermined code associated with one of the lock-in positions. The surveying pole also includes a coded-identifier reader for reading the code of a respective coded identifier associated with the respective lock-in position, a communication device configured for transmitting a signal to a surveying instrument, wherein the signal is based at least on the read code.Type: GrantFiled: July 16, 2019Date of Patent: July 18, 2023Assignee: LEICA GEOSYSTEMS AGInventors: Walter Hollenstein, Markus Geser, Josef Müller, Oliver Faix

Patent number: 11578976Abstract: A target of a geodetic system based on global and local identification references. The target comprises a light emitter (LE) for emitting n predetermined modulated light patterns (MLPs) permanently assigned to one of m (m>n) global identification reference (GIR). The target transmits or receives data based on the assigned GIR. The geodetic system further comprises a geodetic surveying instrument comprising an optical sensor (OS) receives the MLPs and digitizes them using a fast sampling analogue-to-digital converter (ADC). A computing system selects one of the targets or receives a selection of the at least one target assigned to a selected GIR. One of n local identification references (LIRs) is temporarily assigned to the selected GIR. The light emitter of the selected target is directed to emit an MLP corresponding with the assigned LIR. Thus, by detection of the assigned LIR, the selected target is identified.Type: GrantFiled: August 19, 2020Date of Patent: February 14, 2023Assignee: LEICA GEOSYSTEMS AGInventors: Markus Geser, Daniel Hofstetter, Martin Mayer

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
