多功能智能导向定位拐杖的研究

Study on Multifunctional Intelligent Navigation and Positioning Crutch

摘要: 现如今，老年人口与视障人群数量逐年增加。他们的出行安全与自主活动能力早已成为重要的社会民生问题。传统拐杖、盲杖一般仅仅只是基础的支撑作用，缺乏面对复杂环境或突发危险的处理。在此背景下，我们融合多种技术，响应国家号召，从面对复杂场景下的多维度障碍物精准感知、产品的适老化与人机交互、室内外高精度导航定位、产品长续航要求与硬件系统设计、降低成本与产业落地等五大维度出发，依次采用YOLOv7-tiny模型、NLG技术、DeepSORT算法、设计供电系统总体架构等方案逐一解决，研发出具有环境感知、精准定位、智能导向、安全预警功能的智能拐杖，为解决特殊群体出行等难题做出贡献。

Abstract: The number of the elderly and visually impaired populations is increasing year by year. Their travel safety and independent mobility have long become important social issues. Traditional walking sticks and blind sticks generally only provide basic support, lacking the ability to handle complex environments or sudden dangers. In this context, integrating multiple technologies and responding to national calls, we have developed an intelligent crutch with environmental perception, precise positioning, intelligent guidance, and safety warning functions. It addresses five key dimensions: multi-dimensional accurate perception of obstacles in complex scenarios, age-friendly product design and human-computer interaction, high-precision indoor and outdoor navigation and positioning, hardware system design with long battery life requirements, and cost reduction for industrial implementation. Specifically, we adopt solutions such as YOLOv7-tiny model, NLG technology, DeepSORT algorithm, and design the overall power supply system architecture to solve these problems one by one, contributing to addressing the travel difficulties of special groups.
