The invention relates to a train approaching early warning method and system and a computer readable storage medium. When a laser distance measurement value of a laser distance detection assembly is smaller than a first threshold value, and the instantaneous speed of a moving target in image data acquired by a camera assembly is always larger than a second threshold value within first time; if yes, the train passes through a laser distance detection assembly, and then when constructors and/or equipment are located in a construction area, early warning is conducted; otherwise, no early warning is carried out. In the above steps, the stability of triggering early warning is ensured by using the stability of laser ranging, the train is determined to pass only when the instantaneous speed of the moving target in the image data is kept for a certain time, misjudgment caused by passing of other high-speed objects is avoided, then early warning is carried out by combining whether constructors and/or equipment exist in the construction area, and the accuracy of early warning is improved. The condition of alarm caused by unaffected obstacles in a construction area is eliminated, so that the monitoring precision is ensured, and false alarm is avoided.

    本申请涉及一种列车抵近预警方法、系统及计算机可读存储介质,当激光距离检测组件的激光测距值小于第一阈值时,且摄像头组件获取的图像数据中的运动目标的瞬时速度在第一时间内始终大于第二阈值,则列车经过激光距离检测组件,然后当施工人员和\或设备位于施工区域内,进行预警;反之,不进行预警。以上步骤中利用激光测距的稳定性,保证触发预警的稳定性,且仅在图像数据中的运动目标的瞬时速度保持一定时间才认定有列车经过,避免了其他高速物体经过带来的误判,然后结合施工区域内是否存在施工人员和\或设备进行预警,排除了施工区域没有影响的障碍物导致报警的情况出现,从而保证了监测精度,避免误报警。
