Optimal Sampling Strategies for Point-to-Point Line-Of-Sight Calculations in Urban Regions

Research output: Chapter in Book/Report/Conference proceedingChapter

Abstract / Description of output

Smartphone applications are driving a growing interest in 3D modelling – in particular the use of LiDAR for modelling city landscapes at high levels of precision and accuracy. In such dynamic environments, where we wish to make decisions based on places of interest that are in the (rapidly changing) field of view, it is critical that we address performance issues in visibility analysis. This paper
explores optimisation of a point-to-point line-of-sight algorithm, outlining a variety of line of sight sampling strategies, together with a number of trials that enabled us to optimise sampling in the context of urban visibility analysis.
