摘　　要：提出一种基于阴影莫尔法的凹凸字符图像获取方法,针对压印凹凸字符的特点给出了基于阴影莫尔法的字符图像获取的理论分析.进行了光栅传感器的设计计算,设计了实验装置,并将实验结果进行了对比分析.实验证明了采用阴影莫尔法采集的字符图像与光栅传感器的设计计算结果是相吻合的.使用此实验装置对压印字符进行质量检测是一种可行的方法,而且具有检测方法简洁、快速的优点,适合压印凹凸字符的在线质量检测.The method of protuberant characters image acquisition based on shadow moire is presented. It provides the theory analysis of protuberant character image acquisition using shadow moire according to characters＇ features. The grating sensor and experiment setups were designed. The experiment results were analyzed contrastively. The results show that the image using shadow moire capture is fitting to the calculation of grating sensor. The protuberant character quality test using the experiment setup is feasible, simple and quickly. The method is adapted to protuberant characters quality test on line.
