摘要
研究基于超声波测距的智能轮椅避障系统的硬件和软件设计。采用多个超声波传感器,将其测得的数据根据障碍物类型,进行相应的处理,以得到较精确的障碍物的距离信息。在实验的基础上,对不同障碍物类型分析、归纳,提出了智能轮椅的避障策略。实验证明:设计的避障系统具有较高的精度,可以满足智能轮椅在室内环境的避障要求。
The design of hardware and software for intelligent wheelchair obstacle avoidance system based on ultrasonic distance measurement is described in the paper.The system uses several ultrasonic sensors,and processes the measured data according to different types of obstacles to obtain more precise information of the distance.Meanwhile,through the analysis of different types of obstacles on basis of experiments,the intelligent wheelchair obstacle avoidance strategy is proposed.The experiment shows that the obstacle avoidance system has high accuracy and can meet the obstacle avoidance requirements of intelligent wheelchair in indoor environments.
