| 摘 要： | 针对移动机器人数字路标的识别提出一种增强的序贯相似性检测算法（SSDA，sequence similar detectiona—rithmetic），算法中的阈值采用单调递减的阈值序列，阈值逐渐逼近最佳阈值，从而使非匹配区域经过尽量少的计算超过阂值而被丢弃，有效改善识别的实时性。通过实验表明该算法能够快速准确地完成数字路标识别。

| Abstract: | A sequence similar detection arithmetic （SSDA） enhancement algorithm was put forward to recognize the digital landmarks in mobile robot vision navigation. The sequence of monotone decreasing thresholds, approached to the optimal threshold gradually, was used in the algorithm to save calculation of non-matching region and discard them sooner. The enhanced SSDA algorithm realizes real-time landmark detection, and experiments show that this algorithm can recognize the digital landmarks effectively and accurately. |
