摘要
利用DSP(Datasampling)处理器及ADC芯片对触摸屏上的手写轨迹进行实时采样 ,给出硬件结构及软件设计流程 ,重点对坐标变换的定位、飞点处理等字形采样问题进行原理分析并提出解决办法。采用本设计方案所得的采样结果可很好地用于识别系统。
The paper introduces how to realize real-time data sampling for handwriting recognition with the digital signal processor and the ADC,concerning with the sampling module and the sampling process. In the data sampling process, the problems of the coordinate transformation and the process of the unreasonable sampling points are analysed in the theory and resolved.The recognition result shows the sampling is applicant.
