Suzhou Dewo Intelligent System Co., Ltd., incorporated by several Chinese doctors studying in America, is a key leading enterprise supported by Kunshan city. It is situated in Kunshan Returned Student Incubation Park.Ever since its inception, Dewo has been committed to the R&D and manufacture of automatic recognition products and has become one of the innovative leaders in the two-dimensional code automatic recognition and machine vision fields.Dewo expands methods that can effectively estimate and sort noise data and applies them into fuzzy recognition and machine vision technologies. The successful development of multi-video and view abstraction technologies can greatly reduce man-machine interaction needed for segmentation of video and keyframe image sets, thus facilitating the precision segmentation of video and image sets. This method, used as standard test data by a German Research Institute, has been introduced by the most famous monitoring equipment manufacturer in domestic market and achieved technological transformation. Therefore, Dewo is in the leading position in term of sampling-based image set segmentation, application and transformation of video abstraction technology and machine vision technology.The high-speed fixed two-dimensional code scanner launched by Dewo has broken the monopoly of foreign brands in this area, realized photographing and recognition to two-dimensional codes flowing on the assembly line at a high speed, and has been applied in assembly line integration of a number of pharmaceutical manufacturers. China's first DPM two-dimensional code scanner has achieved identification to laser-induced thermal etched two-dimensional codes and pin-point codes and filled up blank in the fields of highly difficult barcode recognition of auto parts, mobile phone parts and the like.Mobile phone screen two-dimensional code scanners launched by Dewo, characterized by high first recognition degree and strong anti-interference ability, are applicable to the recognition and reading of a variety of models of and different brightness of mobile phone two-dimensional codes and have gone through 30 million times of limit decoding tests. Now, they have been applied in payment scenes of various shopping malls and supermarkets and Dewo has become a synonym of "sensitive and durable" two-dimensional code scanner in the industry.
