Minimization Method of Reading Error in Postal 4 State Bar Code Reader
우편용 4 State 바코드시스템의 판독오차 최소화 방법
Abstract
Recently many efforts on the development of automatic processing system for delivery sequence sorting have been performed in ETRI, which requires the use of postal 4 state bar code system to encode delivery points. This paper addresses the issue on the reduction of reading error in postal 4 state raster beam based bar code reader by adjusting measured values of bar code width to its average value over each interval. The test results show that the above method reduces the average reading error rate approximately by 90-100%.
