【摘要】 针对现有导盲设备无法提供全面的导航及避障服务的问题，设计一种基于MaixPy与YOLOv5模型的可穿戴导盲仪。以Maixduino作为MCU终端设备，采用OpenCV与YOLOv5模型来识别盲道与障碍物的种类，利用百度API实现路径规划与语音识别。该导盲仪具有路径规划、盲道识别、障碍物及危险路况智能检测和语音播报功能，能够为弱视群体提供安全可靠的出行服务。更多还原

【Abstract】 Aiming at the problem that the existing blind guide equipment can not provide comprehensive navigation and obstacle avoidance services,a wearable blind guide instrument based on MaixPy and YOLOv5 model is designed.Taking Maixduino as MCU terminal equipment,OpenCVand YOLOv5 model are used to identify the types of blind roads and obstacles,and Baidu API is used to realize path planning and speech recognition.The blind guide instrument has the functions of path planning,blind road recognition,intelligent detection of obstacles and dangerous road conditions and voice broadcasting,and can provide safe and reliable travel services for amblyopia group.更多还原
