Miha Nagelj (2011) Online road network routing system with high definition video. EngD thesis.
Abstract
New technology enables the capture of road digital video recordings and associated spatial data. Together, they are used by various departments in particular to review the state of the road, traffic signs and other road infrastructure facilities. All this can be performed without having to visit the field. Recordings of road sections can also be used for purposes of navigation over the road network. In my thesis, I first developed software to convert source video recordings of roads to the form suitable for web publishing. Resulting video clips and spatial data of the road network are then used by web service which generates data structures necessary for finding the shortest path between nodes in the network. This information is used by the routing module, which implements an effective and fast algorithm to find the shortest path on demand. All parts of solution are brought together by the rich internet application. It contains an interactive map, module for the shortest path calculation and high definition video player of road sections. The user can plan a route with multiple stops using interactive map in web browser and in addition to conventional display of route on the map, the user is provided with a realistic view of the road. User can observe the surroundings of the route and can also dynamically measure the transverse length of the objects or natural barriers on the road. Application provides all the information needed for route planning and is intended primarily for planning of heavy transport.
