Technology Demonstrators

BIMProve demonstrators covering stationary, ground- and UAV-based data acquisition systems; augmented reality (AR) visualisation of BIM model; application of multi-user virtual reality (VR); computer vision model for detection of safety structures in the construction site; mapping of point clouds to IFC elements; and BIMprove web front end

Augmented Reality (AR) visualisation of BIM Model

Description
The demo shows BIM@Construction AR tool demonstrated with Android table and Microsoft HoloLens 2 devices.
Outcome
The following functionalities have been demonstrated: BIM Model visualisation in AR in 1st and 3rd person point of view.

Multi-User Virtual Reality

Description
The demo shows the different functionalities already implemented in the MUVR-Viewer.
Outcome
The following functionalities have been implemented and tested successfully for both PC- and VR-users: a) automatically loading 3D-geometry (including point cloud-data) and deriving a user-menu from it; b) connecting to a virtual room and joining a multi-user-session; c) (de-)selecting 3D-models to show/hide them; d) 1st rudimentary version of issue management; and e) means of remote communication.

Ground Robot BIMprove system integration and operation

Description
The demo shows how the localization and navigation on ground robots works, by illustrating the integration between Bimsync and Robotnik's Backend, in which one the robot automatically gets both 2D and 3D model and use them to locate and navigate on site.
Outcome
The use of 2D-3D BIM models for ground robot navigation and localization.

Leica BLK 360 Point-clouds scans

Description
The demo shows the Leica BLK360 laser scanning the scene by obtaining the point cloud, heat map and high resolution images.
Outcome
Through the SW Cyclone the laser scanning information is obtained and allows to export it to e57 for its interpretation.

Data-capturing drones

Description
The demos shows the indoor helicopter flight with on-board sensors, gimbal camera for data capture, and the process of scanning at fixed distance and angle to wall.
Outcome
A stable flight, flexible system, and extendable with other sensors/needs.

Detection of safety structures and untidy places in images

Description
The demo shows the computer vision based analyser finds safety barriers, safety nets and untidy places from the construction site images. These are pointed out with rectangles in the images. Health and safety inspections are required at construction sites to prevent accidents including falling from heights and fire hazards. In BIMprove, safety inspections will be supported by computer vision.
Outcome
Computer vision model for detecting safety barriers, safety nets, and untidy places in received images. Web UI for viewing the results.

Mapping point clouds to IFC-elements

Description
The demos shows the classification of which points in a cloud that belongs to a certain IFC-element.
Outcome
Two point clouds, one consisting of all points mapped to an ifc-element and the second is all points to mapped to an ifc-element.

Revision change visualisation

Description
The demo shows BIMSync Backend register revisions update of IFC-file, which produces a difference file between original and new revision.
Outcome
Colored IFC-file illustrating the difference and a BCF issue list.

Schedule import and view

Description
The demo shows the import schedule from Microsoft Project native format into a database, and this data in a Gantt diagram on a web page.
Outcome
Import and viewing of schedule works with MPP files.

BIM@Vehicle: First Version of the UI

Description
The demo shows BIM@Vehicle tools UI concept as normal navigator like 2D UI. User could enhance it by link it to AR tool, in this case Microsoft HoloLens 2 device.
Outcome
Tools functionalities has been demonstrated in XR lab environment due to COVID-19 restrictions. User could visualized BIM Model and path to Point of Interest in 1st and 3rd person view. 1st person view has been done via AR with Hololens 2 and 3rd person view is exploiting Android tablet.
