Terrestrial Mapping (2.01)

This Project deals with techniques and algorithms for the detection, recognition and analysis of low-level and high-level features from mobile mapping data along urban and rural transport corridors.

Mobile mapping systems use integrated vehicle-borne positioning, imaging and laser scanning sensors to record data that cannot be readily acquired from aerial and satellite platforms. Examples include vertical building facades and street furniture. Low-level features include edges, corners, planar surfaces, and high-level features include buildings, road signs and the attributes of other man-made and natural features within the transport corridors.

The research uses fused imagery, video, LiDAR, GNSS and sensor orientation data recorded by mobile mapping platforms to recognise, locate, map and measure the spatial attributes and characteristics of features of interest.

Automatic feature extraction for spatial information product generation is essential for organisations such as local government authorities and other government agencies, as well as for 43pl companies, to more efficiently monitor and manage transport corridor infrastructure and associated assets such as power lines, roads and railways, and street-side furniture.

Project Overview

Geoff West, Conference 2012

What is unique is the adoption and enhancement of state-of-the-art feature extraction approaches from the computer vision, photogrammetry, image processing and artificial intelligence domains, and the focussing of these methods on solving the problem of automating the spatial data-to-information process for terrestrial mobile mapping systems

Research Themes

  1. The most appropriate low-level feature detectors for 2D imagery and dense 3D point clouds
  2. Optimal high-level feature recognition algorithms that use 2D and 3D low-level features to support accurate and reliable user defined high-level feature recognition and positioning
  3. Interactive software tools to efficiently configure the recognition process for specific high-level features
  4. Software tools to automate specific analysis and feature measurement tasks based on high-level feature attributes
