摘　　要：随着定位与导航技术的发展,车载导航设备被广泛应用。相较于触摸式导航设备,语音导航由声音控制、操作更加方便。然而,常见语音导航设备无法准确判定出声音信号的来源;此外,车内外噪音也对其造成干扰。针对上述问题,本文设计开发一种基于视觉检测的语音导航抗干扰系统。由司机正面的摄像头对其嘴部动作进行检测,进而获取控制声音信号的时间窗。通过对司机声音信号的准确检测,增强司机对语音导航的控制权限,减少车内外的噪音干扰。经实验表明,本系统的检测准确率高(90%)、实时性能好(60FPS)。且对于司机正面、侧面多角度下,均能够有效地减少车内外噪音对司机语音控制权限的干扰。With the development of positioning and navigation technology,vehicle navigation equipment is widely used.Com⁃pared with touch-based navigation devices,voice navigation is controlled by voice and is more convenient to operate.However,com⁃mon voice navigation equipment cannot accurately determine the source of the sound signal.In addition,noise both inside and outside the car also causes interference.In response to the above problems,our team design and develop a voice navigation anti-jamming sys⁃tem based on visual inspection.The driver's mouth movement is detected by the front camera,and then the time window for controlling the sound signal is obtained.Through accurate detection of the driver's voice signal,enhance the driver's control over voice navigation and reduce internal and external noise interference.The experimental results show that the system has high detection accuracy(90%)and good real-time performance(60FPS).And for the driver's front and side angles,it can effectively reduce the interference of noise inside and outside the car on the driver's voice control authority.
