Embodiment Construction

[0054] figure 1 An exemplary embodiment of the invention is shown at a building construction site location 4 . A worker 11 has a portable networked electronic measuring device 1 configured to establish an online communication link to one or more databases DB, eg to one or more BIM server units 15 . These server units 15 store a generic construction database DB comprising structured data sets of virtual object entities representing planned or constructed physical construction components at the worksite. The database DB, or a synchronized at least partial copy thereof, may be stored locally at the device 1 , somewhere at the worksite 4 or remotely from the worksite 4 . It comprises a data set of CAD (Computer Aided Design) information of physical construction components by which the desired construction result will be constructed. In addition to those CAD data in machine readable form, the database DB may also include other attribute information of the physical construction co...

Abstract

The invention relates to construction site referencing. The invention relates to a method of automated spatial worksite referencing of a networked electronic measuring device with awareness of a rough location information of itself at a worksite location. The method includes querying a database for construction plan information about the rough location and its vicinity and about an actual work progress, computing an actual-state nominal spatial information at the rough location and its vicinity, automatically determining of a fine location of the networked electronic measuring device at the worksite location, by at least one iteration of: automatically determining a measurement point in the vicinity and measuring the measurement point using measurement functionality of the device, and then automatically assimilating the measurement point to the actual-state nominal spatial information and thereby determining the fine location information. When a desired level of accuracy of the determined fine location is not reached, performed another iteration with another additional measurement point is performed.

Description

technical field [0001] The present invention generally relates to a method for automatic spatial site referencing of networked electronic surveying devices, and to a corresponding system and to a computer program product. Background technique [0002] On construction sites, especially buildings, most of the work that must be done requires some kind of spatial reference relative to the site. While in the past craftsmen used wooden folding rules, square levels, and construction drawings or verbal instructions, electronic tools are now often available to assist in those tasks. [0003] For example, EP 2698602 shows a hand-held tool for electronic distance measurement (=EDM) having a support with corner joints providing angular reference information. From this, geometric data of the room can be collected. EP 2458328 shows a monitoring instrument for measuring and marking points on a construction site. It includes a laser EDM and an angle sensor and can be used for plumbing. ...
