基于HSV空间的禁令交通标志检测方法研究

Research on ban traffic sign detection method based on HSV Space

提出了一种基于HSV彩色空间的禁令交通标志检测方法 ,利用禁令交通标志的背景均为红色这一特性,通过统计分析计算出红色的H阈值进行颜色的分割,再利用相关满足条件筛去不符合交通标志的区域,将真正禁令标志所在的区域检测出来,便于进行下一步识别。实验表明该方法是尺度恒定的,能够在复杂的交通场景中进行可靠的禁令交通标志检测。

Proposed ban traffic sign detection method based on HSV color space, the use of the ban traffic signs are red background of this feature, through statistical analysis to calculate H threshold red color segmentation, re-use is not related to the condition screen region in line with traffic signs, prohibition signs the zone where the real detected, the next step for easy identification. Experiments show that the method is a constant scale, can be reliably detected ban traffic signs in complex traffic scenarios.
