Embodiment Construction

[0070] figure 1 is an exemplary flowchart of one embodiment of the method 100 . In step 110 at least one image and / or scan 3a-3c is recorded respectively at a plurality of positions on the construction site 2 and / or in a plurality of orientations of the mobile device 1, the at least one image and / or scan 3a-3c At least a part of the construction site 2 is shown. Thus, for example, the user of the mobile device 1 can walk around the site 2 with the mobile device, or can also stand at a fixed position and turn around its own axis. Additionally, in each recording 110 according to block 111 a position 12a-12c and / or an orientation 13a-13c of the mobile device 1 in the internal coordinate system 11 of the mobile device 1 is recorded by the sensor. Data recorded in this way is in figure 2 in detail.

[0071] Alternatively or in combination therewith, in step 120 the positions 4a-4c of the mobile device 1 are respectively determined in a coordinate system 4 at a plurality of pos...

Abstract

The invention relates to a method (100) for calibrating an internal coordinate system (11) of a mobile device (1) relative to an absolute coordinate system (21) of a construction site (2), comprising the steps: recording (110) images and / or scans (3a-3c) which show at least part of the construction site (2) and / or determining (120) positions (4a-4c) of the mobile device (1) in a fixed coordinate system (4) using a terrestrial or satellite-based positioning system; additionally detecting (111, 121), using sensors, the position (12a-12c) and / or orientation (13a-13c) of the mobile device (1) in the internal coordinate system (11) of the mobile device (1); establishing (130) equations (51-56) having unknowns (5a-5c) which characterise the transformation sought between the internal coordinate system (11) of the mobile device (1) and the absolute coordinate system (21) of the construction site (2), by identifying (131) geometric features (22) and / or by comparing (132) determined positions, the unknowns (5a-5c) being calculated (140) as solutions of an equation system (5) formed from the established equations (51-56). The invention also relates to a method (200) for the quality control of formwork and / or scaffolding.

Description

[0001] Cross References to Related Applications [0002] This application claims priority from German Patent Application No. 102019105015.4 filed on February 27, 2019, which is hereby incorporated by reference in its entirety. [0003] The present invention relates to computer-implemented assistance in the erection and control of field formwork and scaffolding on construction sites. Background technique [0004] When making buildings by pouring concrete, the formwork is often used as a casting mold for the fresh concrete. In order that the formwork can be produced quickly and the material can be reused several times, a formwork system comprising prefabricated standard elements is used. An exemplary formwork system of this kind is known from document WO 2005 / 040525 A1. Likewise, scaffolding is built from prefabricated standard elements. [0005] As the formwork and scaffolding market has become more specialized, so has the complexity of formwork and scaffolding. In many cas...
