The origin of OCR Technology
OCR technology currently, subdivision: OCR ID card, driving license OCR, passport OCR, OCR of bank card, license plate number OCR, OCR documents, OCR, OCR documents, invoices OCR, business card OCR, these are based on character recognition technology, deviate from them.
OCR technology is actually a very old technology, the first is originated in foreign countries, China started relatively late, we detail the origin of OCR technology, and the history of the development of OCR technology in china.
In fact, the concept of OCR is in 1929, by the German Tausheck first proposed, and then is the United States a named Handel, science, put forward the idea of using software technology of character recognition.
But the earliest of printed Chinese character recognition of research is IBM's Casey and Nagy, they in 1966,: the first article on the Chinese character recognition, using the template matching method to recognize the 1000 printed Chinese character, was already very cattle.
.
In 60, 70 years, many countries have begun to study the OCR, the initial recognition method is mainly based on text, and the recognition of the text is only 0 to 9 of the number. Japan began in 1960 OCR research basic recognition theory, the beginning to digital, until 1965 to 1970, began to have some simple product, such as a printed text zip code recognition system, the postal code to identify email help post office as a regional distribution for industry; so far the postal code has been advocated by the national written address.
China in the OCR technology research work started late in the 70's began to study the numbers, letters and symbols of the alphabet, the end of the 70's to start the study of Chinese character recognition. To 1986, the National Science Committee proposed 863 high technology research program, the research on Chinese character recognition into a substantive stage, Ding Xiao Qing professor of Tsinghua University and the Chinese Academy of Sciences, respectively, the development of research, Tsinghua University in 1992 launched a China's first Chinese character recognition software th-ocr, now the leader of Chinese character OCR technology. But in the early stage because there is no good image acquisition equipment, TH-OCR has not been very good application. Until the 90's into the's, with the extensive application of the platform scanner, greatly promoting the further development of OCR technology, so that the recognition accuracy rate of OCR, the recognition rate to meet the requirements of the majority of users. TH-OCR products have also been a rapid upgrade. Even today, TH-OCR is still a very classic products, market share is still very high. Contains the subsequent use of the Microsoft TH-OCR in the office, including HP and other PC manufacturers, are pre installed TH-OCR software.
TH-OCR currently can identify more than 26000 Chinese characters, the recognition rate reached 99.97%. in terms of the number of Chinese characters can be identified, or the recognition rate is far ahead.
