The invention relates to the technical field of traffic signal control, in particular to a method for assisting a visually impaired person to pass through a pedestrian crossing line. The data processing terminal is used for receiving real-time motion data collected by the 360-degree thermal imaging holder and the laser radar. Under the action of a control signal sent by the data processing terminal, the road warning screen can remind a driver to pay attention to the visually impaired person by means of real-time display of text content, and the voice broadcast device can remind the driver to pay attention to the visually impaired person by means of real-time voice broadcast content. And the visually impaired people can know that the visually impaired people are located in the pedestrian crosswalk line area. Therefore, on one hand, the technical transformation from'civil defense 'to'technical defense' is realized, the problem that visually impaired people safely pass through the pedestrian crosswalk line is solved, the method can be widely applied to pedestrian crosswalk line scenes with poor street crossing sight distance, and visual defects of people are made up by utilizing'technical defense '; on the other hand, visually impaired people can be intelligently screened out and tracked in real time.
本发明涉及交通信号控制技术领域,尤其是一种视障人士辅助穿行人行横道线方法。数据处理终端用来接收360°热成像云台和激光雷达所采集到的实时运动数据。在来自于数据处理终端所发出控制信号的作用下,道路警示屏得以借助于实时显示文字内容以提醒司机留意视障人士,语音播报设备得以借助于实时语音播报内容以提醒司机留意视障人士,且视障人士据此以知晓其正位于人行横道线区域。如此,一方面,实现了由“人防”向“技防”的上技术转变,不但满足了视障人士安全穿行人行横道线问题,还可广泛应用于过街视距较差的人行横道线场景,利用“技防”弥补人的视觉缺陷;另一方面,可智能地筛选出视障人士,并对其进行实时跟踪。
