【摘要】：为了保障盲人行路安全,设计基于智能视觉导航的盲人指路设备。介绍了设备设计方案,为智能视觉模块选择CMOS单片机和OV单片机,周期性地采集盲人行路图像,通过对比图像灰度值确定路面是否存在障碍物。采用PFGA控制智能视觉模块时序,计算障碍物位置,进而提供导航线路,通过串口通信电路将导航线路传给语音模块进行播报。通过对比实验证明,基于智能视觉导航的盲人指路设备具备较强的实时性和鲁棒性。
[Abstract]:In order to ensure the safety of blind people, a blind guide device based on intelligent visual navigation is designed. The design scheme of the equipment is introduced. The CMOS and OV microcontroller are selected for the intelligent visual module. The blind road images are collected periodically, and the road obstacles are determined by comparing the gray values of the images. The PFGA is used to control the timing of the intelligent visual module, to calculate the position of the obstacle, and then to provide the navigation circuit. The navigation circuit is transmitted to the voice module through the serial communication circuit. The comparison experiment shows that the blind guide device based on intelligent visual navigation has strong real-time and robustness.
