The embodiment of the invention provides a safety early warning method and device based on traffic intersection recognition and electronic equipment. The method comprises the steps of acquiring road surface video data in front of a vehicle in real time; converting the road surface video data into a plurality of to-be-identified pictures; inputting the plurality of to-be-identified pictures into apreset traffic sign identification model to obtain an intersection sign identification result, and determining whether a vehicle is about to arrive at or drive away from the traffic intersection according to the identification result, the identification result comprising whether an intersection sign exists, and the intersection signs comprising a pedestrian crossing sign, a pedestrian crossing forecast sign, an intersection deceleration line sign and a guide arrow sign; if it is determined that the vehicle is about to arrive at or drive away from the traffic intersection, generating safety early warning information, the traffic sign recognition model being a model obtained through machine learning training by taking image features and intersection sign features determined according to roadsurface picture samples under different weather or illumination conditions as input. The method can remind a driver to observe road conditions and decelerate in time, so that the driving safety is improved.
本发明实施例提供了一种基于交通路口识别的安全预警方法、装置及电子设备,该方法包括:实时获取车辆前方的路面视频数据;将路面视频数据转换成多个待识别图片;将多个待识别图片输入预设的交通标识识别模型,获得路口标识的识别结果,根据识别结果确定车辆是否即将到达或驶离交通路口,识别结果包括是否存在路口标识;路口标识包括人行横道标识、人行横道预告标识、路口减速线标识和导向箭头标识;若确定车辆即将到达或驶离交通路口,生成安全预警信息;其中,交通标识识别模型为根据不同天气或光照条件下路面图片样本确定的图像特征和路口标识特征作为输入,通过机器学习训练得到的模型,本方法能提醒驾驶员观察路况以及时减速,提高行车安全。
