The 4D construction learning environment production guide has been developed to assist project teams intending to produce virtual tour surveys of a construction site that is to be included in the suite of online UQ 4D construction learning environment (4Dcle) sites. The overall goal of a 4Dcle project is to document the construction (or refurbishment) process of a selected building for (online) use in teaching and learning activities by educators and students of professions related to the construction industry.
In addition to the main guide, which provides advice and detailed instructions on all key areas of the production process, a set of ‘QuickStart guides’ (2-page workflow and essential information summaries) is also available for viewing/ downloading. Documents substantially revised since 31 May 2018 are indicated by a short date in brackets.
Image processing 1 – stitching (and settings)
Image processing 2 – virtual tour rendering in PTP (and settings)
Folder and files - structures/ naming conventions for Images and Other resources (5/12/18)
Data quality checking (5/12/18)
The 4D construction learning environment is curated by Dr Chris Landorf, School of Architecture, The University of Queensland. Inquiries about contributing to the library of virtual tour sites should be directed to Dr Landorf at the UQ School of Architecture.
Outlines key issues to take into account during project preparation, providing advice on scoping your project and estimating resource needs and costs.
This contains ‘How to’ instructions for creating the minimap(s) used for navigating the virtual tour site in conjunction with the placement of nodes (survey camera positions) on site. You also find advice here on locating nodes on the site, the site map and (Cartesian grid) coordinate system. You will need to download the template MinimapNodeSurveyData.xls (5/12/18) to use in conjunction with node surveying.
This guide provides a briefing on minimum requirements, with recommendations, for suitable photographic equipment and image processing hardware and software
The finished quality of a virtual tour is entirely constrained by the quality of the original photographic images. This guide provides a practical reference for survey photographers.
Step-by-step instructions are included for both stitching the node panoramas (illustrated with reference to AutoPano) and rendering survey virtual tours (in PanoTour)
This outlines the main requirements for building a library of construction documents and other resources to support proposed learning activities. You will also need to download the Excel inventory template ResourceInventory.xls (5/12/18)
