RASTER IMAGE VECTOR CONVERSION METHOD BASED ON COMPUTERIZED AUTOMATION

摘要

PROBLEM TO BE SOLVED: To provide a vector conversion method which is free of problems, such as difficulties in processing of a crossing line, a short line, and a distorted line and a low-processing speed in the conventional methods, for vector conversion of a line network organization.;SOLUTION: A line, an intersection, and a shape of a bitmapped image of the line network are analyzed, and when these are processed sequentially, the network organization is turned into a vector.;COPYRIGHT: (C)2002,JPO
