    • Abstract
  • Automatic acquisition of centre line among curve is extensively applied to geographic information system and computer cartography.After analyzing the current acquisition algorithm of centre line,we put forward the generation algorithm for centre line based on the model of approaching intersection of buffering borderline from reciprocal direction(MAIBBRD),and expatiate the keystone and solution steps of the model.At last,by applying SuperMap Objects control under the condition of VC++,some experiments have been done to validate the algorithm's validity.The experiments show that the algorithm is characterized by low difficulty in programming realization,easy shape control of centre line,cushy adaptation of complicated curve configuration,and so on.
