It analyses and researches the important contents about the system. Then it provides the solutions of main problems. In recognition algorithm, bining template matching with feature recognition, it put forword an improved template matching algorithm based on feature weights. The algorithm can obviously improve the char recognition ratio. Keyword: image processing。 pattern recognition。 feature weights。 software design 0 Introductions Character recognition of image coding is still the subject of intense study at home and abroad, it has broad applications, such as Automatic number plate recognition, postal code of the automatic identification, automatic reading papers, reports, automatic processing, because of this online image coded character recognition has some mon, this paper online tire coding character recognition system for the general image coding character recognition system has been elaborated on the key link of the research and analysis, the method of the other online image coded character system Development of guiding significance. 1 An online image coding identification system processes Online image coding character recognition system includes digital image capture, storage, image preprocessing, encoding the image extraction, feature extraction coding, coding identification and followup treatment of some aspects of its flow chart shown in Figure 1. Figure 1line character recognition image coding system flowchart Online tire image coding character recognition system requires the production pipeline through the acquisition of each tire with tire encoded image, and then through image processing, coding to extract features of the tire, using the appropriate Image preprocessing Followup treatment FeaExtraction and Identification Code Coded image capture and storage recognition algorithm to identify each coded character. Tire coding characters as a certain deformation in the tires, and different camera angles, are also great differences in the coding images,
