PURPOSE:To improve a working efficiency considerably, by adopting pattern information processing techniques such as pattern processing and character recognition as the nucleus to read a power distribution drawing and by using this read data as the data base of a computer to mechanize editing and control of the drawing. CONSTITUTION:An input part 1 scans a drawing to convert it to digital information and records this information in a storage device, and the digitized drawing is made binary by a preprocessing part 2 and is subjected to the noise processing and is made a fine line. In a segmentation part 3, characters are segmented to discriminate numbers, ''Kanji''(Chinese character), and other symbols. Discrimination results are transferred to a handwritten number recognizing part 4, a symbol recognizing part 5, a handwritten ''Kanji'' recognizing part 6, and a segment describing part 7, and sizes and angles are normalized to recognize them accurately. The drawing data base obtained by a series of these operations is read out from a data base processing device 8 in accordance with the request from a control device 12 or a terminal equipment 9 and is outputted from an output module 10 as a hard copy in a graphic form. |
