摘要： 针对汽车轮胎生产线检测的智能化管理问题，提出一种嵌入式系统以对轮胎规格号进行快速识别。对图像进行预处理，包括极坐标变换、双线性插值拉伸，利用大津法进行二值化，以连通域方法来提取规格号字符。采用基于统计的方法抽取轮廓特征进行规格号模式识别。系统硬件部分采用高速TMS320C6000系列DSP为核心的嵌入式硬件系统，使用参数预存储、软件流水线技术及双缓冲内存分配等优化方法。实验结果表明，该系统能快速有效地识别汽车轮胎规格号。

Abstract: For Intelligent management of car tire production line, a method of fast recognition of car tire size code which combining a drop-in handware system is presented. Tire image is preprocessed including polar transformation, bilinear interpolation stretching and Da-Jing Method to preprocess tire image, segments specifications by connective region. Outline features of size code is extracted based on statistical methods to recognize tire size code. In the drop-in handware system, TMS320C6000 DSP is applied to realize this algorithm, program can be executed quickly by using methods such as soft assembly line, parameter storage and two-buffer memory allocation technology. Experimental result shows that the system method meets the needs of fast recognition of car tire size code.

Key words: Digital Signal Processor(DSP), connective region, tire size code
