摘　　要：据国内外报告数据,目前视障人士人数逐年增加。视障人士在日常社会生活中有着极大的不便。为了提高视障人士的生活质量,需要提供安全、可靠、便捷的辅助出行设备。导盲杖可以改善视障人士的出行便利性。不搭载传感器的或搭载单一传感器的导盲杖存在功能单一或探测精度低等问题,不能有效地实现辅助出行。本文对当前国内外导盲设备——主要是导盲杖进行调研,从搭载传感器、环境识别算法、路径规划、组合导航及导盲效果等方面进行了分析;最后,对智能导盲杖的发展趋势做了预测。According to reports,visually impaired people are increasing year on year.They suffer from serious inconveniences in daily life.To improve the quality of life for the visually impaired,it is imperative to provide safe,reliable,and convenient auxiliary travel equipment.Guide cane can improve travel convenience for the visually impaired.Guide cane without sensors or with a single sensor have single functions or low detection accuracy and cannot effectively assist travel.This paper reviews current blind guide equipment—mainly guide cane,and analyzes from equipped sensors,environment recognition algorithms,path planning,integrated navigation,and blind guide effects.Finally,the development of smart guide cane and trends are also predicted.
