The invention discloses a paper calendar electronization method and device. The method comprises a paper electronization step, a binarization processing step, an edge recognition step, an image clipping step, a time recognition step, a text recognition step, a result generation step and an electronic document output step. According to the method, an APP in a smartphone and a special calendar are utilized, and analytical processing is performed on a collected image; by aid of an existing OCR (Optical Character Recognition) technology, the problem of low recognition rate is effectively solved; and through one piece of software, cost is lowered, and the purpose of efficient recognition is achieved. The device has the advantages of being high in recognition degree, low in cost, convenient to carry and good in user experience.
