In order to realize digital information quickly recognize of the instruments and gauges and to improve the scientific research and production efficiency,the system use computer image acquisition and processing,the first is information pretreatment for removing unwanted noise and image thinning by character threshold segmentation for preliminary classification of information.The second is further specified classification according to combining morphology and orientation dereferencing to finish information identification.Through use of the VHDL simulation,the experimental result shows that positioning accuracy of the method is higher,threshold segmentation algorithm of research object is good,and easy to implement,and has strong anti-jamming ability,it has a high application value for improving real-time of the system information identification.
