多视预警安全头盔的研究与设计

摘要

Safety problems in travelling with bicycles or motorcycles have been a public concern. To solve the prob-lem, according to the principles of optical refraction, the paper researches and designs to change the optical path through curved surfaces, realizing the forward-looking of the background of helmets. By using a plurality of ultrasonic sensor networks, the effect of the helmet can be achieved. Based on the deformation principle of images while meet-ing obstacles, the paper designs specific projection beam to achieve a highlighted focus on the ground in front of the rider. This design has great early warning and protection functions for the rider, proving to have good application val-ue.%自行车和摩托车在道路行驶过程中的安全问题一直被人们所关注。本文为解决行车时的安全问题，依据光学折射原理，研究并设计曲线光路，实现了头盔后景的前视；利用多个超声波探测传感器组网，达到了头盔可对外来接近物体全方位安全预警的效果；基于图像遇障碍形变的原理，设计了特定的投影光束，实现对前方地面平坦程度的突现显示功能。本设计对于骑车者具有很好的预警和保护作用，且具有很好的应用价值。
