The invention provides a real-time image character recognition cache acceleration system. The system comprises a configuration management server, a processing result cache server and a plurality of image character recognition processing servers; the three servers form a local area network; the system provided by the invention has the advantages that the image character recognition matching speed can be greatly accelerated, by reducing the processing frequency on the repeated texture image, the character recognition matching result of the image in the system is saved in a processing result cache structure; the image character recognition matching related algorithm is not directly adopted when judging whether the character image is the junk multimedia message, but whether the image is processed is searched in the processing result cache structure; and the operation of searching the processing result in the processing result cache structure is faster than performing character recognitionmatching speed by comparing the image.
