GEOMETRIC MODELLING AND 3D SEGMENTATION OF UNMANNED GROUND VEHICLE - COLLECTED POINT CLOUDS

Abstract

The dependency on Building Information Modelling (BIM) of past, existing and future buildings is increasing exponentially. Most construction projects to date are relying on construction technologies, BIM alike, to fast-track activities on critical paths, to improve stakeholder communication with BIM’s inherent nature of presenting information transparently to project stakeholders, to facilitate in project scheduling and more importantly- to provide live progress updates for project progress monitoring purposes.

This paper looks into the manual scan-to-BIM process, which is important in re-constructing 3D digital representations of older projects that were not designed with as-built BIM models, and also in providing construction progress updates to keep project stakeholders and site supervisors well-informed on every phase of construction that is happens on the ground.

This study aims to design a scan-to-BIM framework as a standard procedures that modellers working on scan-to-BIM projects should undertake for a more systematic approach, to overcome the currently lack thereof standardisation of scan-to-BIM procedures. Considerations of obstructions, ambiguities and assumptions have been generally included in the framework, for users to make reference to as a guide.

Assumptions and limitations as well as considerations for future research will be covered in this paper, for users to adopt the framework and possibly improvise and improve on it.
