✦ Synopsis

A system (Sketch Plan) is proposed that offers recognition of scanned floor plans (sketched by hand without use of rulers or other tools), and automatic conversion of walls, stairs, doors, and other architectural elements. Reported in the present paper are input conditions for the proposed system, an algorithm for recognition and interpretation of drawings, and results of performance evaluation. With the algorithm, line elements and area elements are processed separately, and then integrated, which ensures stable recognition of hand-sketched plans with robustness against inaccuracy. Performance tests using actual hand-sketched drawings offered a recognition rate of 93%. In addition, with the proposed system, input time (including confirmation and correction of recognition results) is one-ninth that for mouse-based manual input.
