The invention discloses an intelligent intersection early warning system which comprises a thermal imaging camera, an intersection early warning module and a warning module. When objects such as pedestrians, vehicles, animals and the like appear in a specified visual range, the system can judge whether the front intersection can normally pass or not according to the speeds of the objects such as the pedestrians, the vehicles, the animals and the like, and after judgment and recognition are conducted through an algorithm set by the intersection early warning module, the warning module gives an instruction. The system can be installed at curve parts with insufficient line sight distance, extremely small curve radius positions of roads in mountain areas, intersections (especially intersections without signals) with poor intervisibility, railway crossings and narrow turning positions of underground parking lots, and the situation that road reflectors need to be concerned all the time is avoided. And accidents caused by too fast vehicle speed at the turning intersection and untimely response are avoided. Compared with an existing road reflective mirror, the road reflective mirror solves the problems that the road reflective mirror is easy to dirty and damage, occupies extra space, distracts attention of drivers and the like. Meanwhile, a target detection algorithm is optimized, the target detection algorithm is applied to video detection of the intersection, and a safer, more convenient and more intelligent intersection passing early warning system is provided for automobiles and pedestrians to pass through some special types of intersections.

    本发明公开了一种智能叉路口预警系统,包括热成像摄像仪、路口预警模块、示警模块;当有行人、车辆、动物等物体出现在规定的可视范围内,系统可以根据行人、车辆、动物等物体速度,来判断前方路口是否可以正常通行,通过路口预警模块设定的算法判断识别后,示警模块在作出指示。该系统可以安装在路线视距不足的曲线部分,山岭区道路极小的曲线半径处、通视恶劣的交叉路口(特别是无信号的交叉路口)、铁路道口以及地下停车场的狭窄转弯处,避免需要时刻关注道路反光镜,避免转弯路口车辆速度过快来不及及时做出反应出现事故。与现有的道路反光镜相比,解决了道路反光镜容易脏、易破损,占用额外空间,分散司机注意力等问题。同时优化了目标检测的算法,将目标检测算法应用到路口的视频检测中,为我们的汽车,行人通过一些特殊类型的路口提供了一种更安全的、更便捷的、更智能的智能路口通行预警系统。
