摘要
在现代化城市建设中,已开始广泛应用地理信息系统技术处理空间数据及其有关各种城市信息。由于扫描仪的限制或纸地图过大,在数字地图的制作上不可避免地存在图幅间拼接的问题。文章着重讨论了图幅拼接功能的算法和实现。
The technique of the Geographic Information System has already been applied in wide fields to deal with special data and something about the managing model of the various city information. Because of the limitation of scanners or big map, the combing problem among pictures is not avoided in making digital map. Taking the two abutting pictures for example, we discussed mainly the arithmetic and realization of combing picture in this text.
