  • 摘要:The paper presents a low-cost navigation system, which is based on digital terrestrial images. The database of the test area is filled by digital images about road junctions, crossings, and other .irregularities" taken with a high-resolution commercial camera. The developed guidance system solves the usual problem within urban circumstances (one or two way streets etc.), which is followed by a systematic image query along the found optimal path. The queried images of the database are extended by simple navigational instructions (arrows) to give visual information for the driver. The obtained image-based itinerary contains more information than the widely used navigation systems, and allows better navigation performance in unknown situations. The paper gives an overview about the planning of the field works, the execution of data acquisition by GPS and photography, as well as the database built-up and how the whole data set is structured and stored. It is followed by the presentation of the implemented algorithms. The use of the developed system is shown on an example executed in Budapest, Hungary
