越来越多的车辆不仅造成了交通拥堵,也使得交通变得更加复杂化。越来越多的交通信息需要通过交通标志传达出来。在复杂交通情况下或者驾驶员没有专注驾驶的情况下,交通标志往往被忽视了。因此,研究一套交通标示自动识别与提示系统就十分有必要。特别是随着智能交通理念的提出和无人驾驶技术的发展,人们要求汽车能够自己主动获取道路交通信息。本文针对交通警示标志进行了检测和识别。通过再HSV颜色空间下进行颜色分割,将交通标志候选区域提取出来,对候选区域进行进一步图像处理,甄别出交通警示标志的区域。本文采用了BP神经网络的方法来识别交通警示标志。首先将标准的交通警示标志作为模板,提取特征对神经网络进行训练,让神经网络记忆选用的交通标志的形状。本文还开发了一个交通警示信息语音提示的功能,事先建立交通警示标志牌、交通警示信息与交通警示提示语音的对应关系,在识别到交通警示标志的时候显示对应的警示信息并播放对应的语音提示。
