Embodiment Construction

[0020] For example, in order to capture steel bars, cables, pipes, holes or similar elements 20 inside a concrete structure 30, in the area scanned by GPR (Ground Penetrating Radar) according to figure 1 (bird's eye view) to implement the present invention. The recorded scan data is linked to a coordinate system. After the scan is completed, the results are processed and distributed to the AR device for displaying AR objects (virtual models, photos, texts, cartoons, etc.), and thereby support the user of the AR device in operations such as drilling. The AR device may be a smart helmet, smart glasses, a tablet computer, a smart phone, and the like.

[0021] Markers 10 for identification and reference are placed within the scanning site. The marker is permanent, ie usually fixed for a long period of time in a defined pose relative to the coordinate system, and may be made of a sustainable material, as the environment may be harsh. Exemplarily, a permanent marker comprising a ...

Abstract

Provided is near field maneuvering for AR-devices using image tracking. The invention relates to an augmented reality (AR)-system intended and configured for use in the field of at least one of metrology, geodesy, and civil engineering. The AR-system comprises a permanent marker having a defined pose relative to a coordinate system; an AR-device having a camera and a processing unit, wherein the AR-device is configured to visually detect and identify the permanent marker and determine a relative pose between the AR-device and the permanent marker; a temporary marker having a coded design and an undefined pose relative to the coordinate system and the permanent marker, wherein the AR-device is configured to visually detect and identify the temporary marker by the coded design, determine a relative pose between the permanent marker and the temporary marker, defining a pose of the temporary marker relative to the coordinate system based on the determined relative pose between the permanent marker and the temporary marker, and determine a relative pose between the AR-device and the temporary marker.

Description

technical field [0001] The invention relates to an AR system according to the general terms of claim 1 , a method according to claim 5 and a use according to claim 11 . Background technique [0002] The technical fields of the invention are metrology, geodesy and civil engineering. In these fields, augmented reality (AR) systems are often used to support users on the premises through referential visualization. [0003] Such AR systems typically include at least one landmark that is precisely set relative to a coordinate system that an AR device (such as an AR helmet, AR glasses, or a tablet / smartphone) can refer itself to by means of the landmark The predetermined pose (pose). Once locked (or in other words: "registered") into the coordinate system, the AR device can display virtual objects with a precise spatial link to the coordinate system (ie to the natural environment). Usually the locked state must be continuously maintained by repeatedly scanning the flag. [0004...
