Abstract
An object of the present invention is to generate a vector or data from inputted drawing data interactively by suppressing the input cost. When an unknown process occurs in the system during data processing, an inquiry to a user is generated in the case of interactive operation. However, when drawings are handled, the number of inquiries to a user increases and the system operability lowers inversely. The present invention executes the drawing recognition method by cooperation and and competition of a multi-agent on the basis of the basic property of a figure such as adjacent relation. When blurring or a problem portion such as in interruption part or a junction part appears during recognition of a drawing, the linkage relation of line paths is automatically decided by making the recognition agent adjacent to the problem portion cooperate and compete. An inquiry to a user is not made. By doing this, vector data is obtained. The input cost of figure information in a data base can be reduced remarkably.
