Staff Profile

Dr Wen Xiao

Lecturer in Laser Scanning and Photogrammetry

Background

Introduction

Wen Xiao joined the Geomatics group within the School of Civil Engineering and Geosciences as a lecturer in 2016. His research interests lie in the technologies of photogrammetry and laser scanning and the applications in urban and natural environments, with a focus on dynamic scene understanding, change detection, feature extraction, and 3D modelling from various platforms, e.g. static and mobile mapping systems, airborne and terrestrial lidar, UAV, crowdsourcing.

Recently, his research topics include:

1: moving object extraction from mobile mapping system

2: individual tree delineation from ALS

3: heritage structure analysis using lidar and low cost photogrammetry
