複数地図の照合による道路情報抽出

抄録

The recent advance of the technology of geographic information systems has led to the need for developing efficient and reliable methods of extracting various information from the huge stock of conventional maps. In this paper, an image processing method is thus proposed for obtaining road segments with high precision using multiple maps. Applying several techniques based on elastic matching of line drawings, the proposed method restores incomplete road segments on a map by referring to other maps containing the corresponding complete segments. Successful experimental results are presented for cases where two maps covering almost the same region are available.
