CLEOPATRA: digitizing engineering drawings

While almost all modern technical drawings are done on computer, countless manually-produced drawings exist and still need to be accessed. In many cases, computer software is needed to turn scanned images into a vector format that allows the images to be processed and manipulated by computer-aided design (CAD) packages. The software developed fills that need, and improves on existing packages in terms of speed and accuracy. Overall, the package represents a significant advance on previous systems, being around three times quicker. A substantial user base has already been established world-wide.

The key to the success is the software's outstanding recognition power for both basic and more complex geometric structures. It features an improved image enhancement system that can process many of the poor contrast drawings that previous systems could not handle. The text recognition function can recognize standard and italic text at all orientations. An optional package is the SYMBOL module that recognizes, and allows replacement of, standard or user-defined symbols. The software system can process a range of image sizes and can input a range of scanned image formats. Batch processing and multi-document processing are both supported.
