The invention discloses a road danger identification method and system for a dangerous goods transportation tank truck. The method comprises the following steps of S1, obtaining a road sign of a surrounding region through a camera based on a high-speed camera technology, and uploading the obtained road sign of the surrounding region to a vehicle-mounted controller, S2, performing preprocessing, image calibration and feature information extraction and recognition on the road signs of the surrounding region in the vehicle-mounted controller by using a pattern recognition technology, and S3, informing a driver of the driving vehicle of the processed picture information in advance in a voice prompt mode, and stopping voice broadcast after feedback of the driver of the vehicle is obtained. The method has the beneficial effects that based on high-speed camera shooting and image recognition technologies, through a binary image connected domain marking assisted by a coordination recommendation method, a vehicle driver can quickly recognize a front road danger mark, an image is obtained through a camera, the vehicle driver is prompted through early warning, the transportation safety is improved, and safety accidents are reduced.

    本发明公开了一种用于危险品运输罐车的道路危险识别的方法和系统,该方法包括以下步骤:S1、基于高速摄像技术利用摄像机获取周边区域的道路标识,并将获取周边区域的道路标识上传至车载控制器;S2、在车载控制器中利用图形识别技术对周边区域的道路标识进行预处理、图像标定及特征信息提取识别;S3、将处理后的图片信息采用语音提示方式提前告知将要行驶的车辆驾驶员,并得到车辆驾驶员的反馈后停止语音播报。有益效果:基于高速摄像、图像识别技术,并通过二值图像连通域标记辅以协调推荐的方法,使得车辆驾驶员快速识别前方道路危险标识,并通过摄像机获得图像,通过预警提示车辆驾驶员,提升运输安全性,减少安全事故。
