This Project researches 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.
The project team has shown their technology developments to Whelans and Landgate.
David Belton and Petra Helmholz visited Vekta in Melbourne to discuss possible project activities. Areas of interest include using developing feature extraction methods to aid in automated BIM generation and the fusion of different spatial datasets (including laser scans) acquired at different times and locations to generate whole of city datasets meeting accuracy requirements.
