Description

Field and background of the invention The invention concerns an assembly for displaying construction-related data in an image of a construction site. The invention also concerns a method for the Displaying construction-related data in an image of a construction site. In the context of the invention, the term 'construction' is used in its broadest sense and refers, in addition to construction of buildings, interiors or infrastructural objects, also regarding maintenance or renovation thereof. Building Information Modelling (BIM) is well known, a process in which, by means of planned hardware and software, construction-related data, such as drawings, texts, labels, symbols, indications, instructions, physical or functional characteristics, dimensions, images of objects, shapes or models are digitized, stored and managed. Building Information Modelling (BIM) is used for design, planning, construction, monitoring of progress and quality, operation, maintenance and management of architectural structures, such as buildings, interiors or infrastructure structures, to optimize. Also well-known is Extended Reality (XR), an umbrella term for Virtual Reality (VR), Augmented Reality (AR) and Mixed Reality (MR). With VR, exclusively a virtual image shown, for example comprehensive images of objects, shapes or models, placed in a virtual environment. In AR, a virtual image, for example, is comprehensive texts, labels, symbols, directions or instructions, combined with a realistic picture of the surroundings, without 'interaction' being possible with elements in the virtual image. In MR, a virtual image, for example comprehensive images of objects, shapes or models, combined with a realistic image of the environment, whereby 'Interaction' is possible with elements in the virtual image. A virtual image can be generated using the hardware and software provided for that purpose, for example, based on data from a digital database. With AR and MR, it is possible the realistic image of the surroundings is captured, for example by means of a camera, and then be displayed, together with the virtual image, on a handheld monitor, for example the screen of a smartphone or laptop, or be directly perceived by a user, where the virtual image is displayed in the user's field of view, for example via a Head-Mounted Display (HMD), a head-worn transparent screen. In AR and MR, the virtual image and the real image must be correctly positioned relative to each other. be displayed. For this purpose, the position of the device in question, such as a camera or an HMD, to be determined and tracked relative to the environment, by means of a suitable positioning system for that purpose. In the context of the, 'position' refers to The invention has always been intended to mean 'location and orientation'. In an interior space, use can be made for this purpose. are made of a Local Positioning System (LPS) comprising beacons, and on the involved device receivers installed for receiving by the beacons emitted electromagnetic signals. Outdoors, use can be made of for this purpose a Global Navigation Satellite System (GNSS), such as GPS, GLONASS, BeiDou, Galileo, QZSS and NAviC, comprising a network of satellites, receivers for receiving of electromagnetic signals transmitted by the satellites, and on the relevant device-mounted sensors, such as an Inertial Measurement Unit (IMU) or a electronic compass, for measuring its position data. For a larger For accuracy and precision, Differential GPS can be used. (DGPS), Precise Point Positioning (PPP), Inertial Navigation Systems (INS), Multi- constellation GNSS or Real-Time Kinematic (RTK) and Virtual Reference Station (VRS) technique. Outdoors, earth-placed devices can also be used for this purpose. transmission towers, for example forming part of a 5G network, and trilateration or triangulation. The position of an involved device, such as a camera or an HMD, can also relative to the environment, are determined and followed, by a current, by a user observed or recorded by a camera, image of the surroundings to compare with previously recorded and stored images of the surroundings. Summary of the invention The goal of the invention now is a solution that combines the benefits of using Building Information Modelling (BIM) as well as the benefits of applying Extended Reality (XR), in particular Augmented Reality (AR) or Mixed Reality (MR), knows. To that end, the invention provides an assembly within the meaning of claim 1 and a method. according to conclusion 12. Examples of implementation An assembly according to the invention comprises a database and means for the means Digitizing Building Information Modelling (BIM), storing it in the database, and managing construction-related data, as well as resources for the, based on the digitized construction-related data, generating a virtual image encompassing the construction- related data, also a screen for displaying the virtual image, and also positioning aids for the correct relative positioning of the displayed virtual image within the image of the construction site. This way, the digitized construction- related data on the construction site in a realistic picture of the construction site, and accurately positioned therein, are shown to a user. In a preferred version, a first part of the database is located the assembly is located at a remote location from the construction site, and the screen is located comprising, second part of the assembly, situated on, or in the immediate vicinity of, the construction site, and the assembly also includes means for exchanging data between the first part and the second part. This way, the construction-related data can be placed on distance from the construction site, for example in a back office, are being digitized, stored in the database, and managed, and on the construction site via the screen in the a realistic picture of the construction site can be shown. In addition, for example, the current 30 realistic image of the construction site extending to the location at a distance from it become sent. In this way, modified or adaptable construction-related data, and the current, realistic image of the construction site, continuously exchanged between the construction site and the location at a distance from it, and can thus, for example, a construction process on are monitored and controlled remotely. In addition, the screen can be a head-worn transparent screen, for example. 5 forming part of a construction helmet. A user can then the realistic image of the directly observe the construction site, while the virtual image, encompassing the construction-related data is perceived via the screen. In addition, the screen can also be a handheld screen, for example the screen of a smartphone or laptop, where the assembly also includes a camera for recording the actual image 10 of the construction site and means for displaying them on the handheld screen If the construction site is situated in an indoor space, the positioning equipment can include beacons, part of a Local Positioning System (LPS). In the case of a head-worn transparent screen respectively a hand-worn one screen, the positioning aids then also include, with the screen respectively the camera, connected receivers for receiving, electromagnetic or acoustic signals originating from the beacons and also means for processing the received signals. In this way, the location and orientation of the screen or the camera respectively are determined in relation to the environment and the virtual image, comprising the construction-related data, in the real image of the construction site, and correctly positioned within it, be shown to the user. If the construction site is situated outdoors, the positioning devices can receivers for receiving electromagnetic signals from satellites part part of a Global Navigation Satellite System (GNSS) or originating from Earth installed transmission masts, for example forming part of a 5G network, include. In the case of a head-worn transparent screen or a hand- mounted display, the positioning aids then also include, with the display respectively connected to the camera, sensors, for example an Inertial Measurement Unit (IMU) or an electronic compass, for determining its position data, and also means for processing the received signals and the specific position data. Such as can again the location and orientation of the screen and the camera respectively be determined in relation to the surroundings and the virtual image, comprising the building related data, in the real-life view of the construction site, and correctly positioned therein, be shown to the user. In another embodiment, the positioning aids include means for the recording and storing images of the construction site, and also means for the comparing a current one, observed by a user or via a camera recorded, image of the construction site with the stored images of the construction site.
