About the research project

This research will consider how point cloud data and immersive visualisation technologies might contribute to the sustainable development and management of built and natural environments in urban areas. It will use sites within the Northern and Southern Transformation Projects of the University of Tasmania as the context of investigation.

Rapidly increasing density and accuracy of 3D point cloud data makes it timely to investigate the potential use of immersive Virtual Reality (VR) applications. VR offers the potential for users to transfer their acquired skills to within a 3D and 1:1 scaled immersive environment, constructed from the point cloud data. For example, inventory field operators have been using VR to perform inventory assessment tasks with high-resolution point cloud data acquired from the forest (Chinthammit, 2019). While users feel immersed and can use their existing skills in a point cloud environment, the accuracy of the assessment tasks performed in VR was inferior to the work performed in the field. The findings prompt the importance of understanding how users perceive and make decisions within an immersive point cloud environment. This research will investigate fundamental visualisation elements such as depth perception, distance estimation and structure estimation of VR representations of point cloud data of urban environments.

Applicants should suggest a provisional project scope that includes (1) an urban site/s from the Northern and Southern Transformation Projects, (2) a set of point cloud characteristics (density, accuracy and precision) and (3) an application domain from within the built environment domain (design, construction, assessment, management and conservation) that would benefit from immersive visualisation. Specifically, the research will look at human perception and task efficacy in relation to practical uses of the point cloud data in the chosen domain. Potential use-cases include conservation and management of built and natural heritage in the urban domains of the transformation projects.
