The digitization of general architectural drawings seems to be a simple scanning operation, but because architectural drawings are not ordinary official documents and are mostly cyanotype drawings, and are folded and filed all year round, uneven yellowing (or redness) creases will occur. If Scanners or general imaging software can easily cause lines and fonts on black and white images to disappear or become unclear. The main reason is that the existing scanners or imaging software functions on the market cannot effectively solve the problem of yellowing (or overpainting) of cyanotypes. Red) Line and text clarity issues within the folds.

Our company has many years of experience in image processing and digitalization of architectural drawings, and has extensive experience in image processing of binarization (black and white) or crease removal of cyanotypes and old drawing files. In order to optimize the processing of architectural drawing images, we can solve At present, large-scale image scanners cannot overcome the problem of yellowing of blueprints (black and white). Our company has specially developed a system for optimizing image processing of architectural drawings. This system has been used by construction management agencies across the country. For It has greatly improved the quality of architectural drawing digitization. This technology has been accepted byPattern Recognition journal (this journal is among the 7% (18/247) high-quality journals ranked in the classification) and has applied for an invention patent.
