Objective:To design patient recognition management system in hospital based on vein recognition technique to realize the accurate control of patient recognition management for better clinical therapeutic effect. Methods:Irradiating the vein vessel in the palm of the hand or the back with infrared ray, then extracting biological feature from the infrared vein image obtained by camera. To make the identify recognition come true, we did some processing such as image capture and preprocessing, feature extraction and match and so on. Results:Both the two key technical indexes arrived at the industry level. The correct recognition rate achieved 98% and the recognition time was less than 0.5s. Conclusion: The Vein recognition is the most difficult to forge, and has the most high security level among all the biology recognition techniques. This system possesses of many advantages of a very low false rejection rate and false acceptance rate, high recognition, and fast recognition speed. Thus it can be widely applied in clinic.
