车载MOST摄像头和人脸识别接口的设计与实现

Design and implementation of vehicle-mounted MOST camera and face recognition interface

将人脸识别技术与MOST车载环状网络结合,提出车载MOST人脸识别模块.在MOST环状网络中添加摄像头和人脸识别接口,采用MOST异步通信方式,通过I2C总线传输数据,并修改MOST帧边界、增加带宽.车载MOST摄像头接口与人脸识别接口共同实现了人脸图像采集、MOST异步通信、身份认证的功能.实验证明,该方法具有可操作性,可以满足实际需求.

In recent years,face recognition technology is more and more mature,which has been widely applied to many fields.At the same time the user demand for automotive safety travel increasingly urgent,so the face recognition technology is combined with vehicle-mounted MOST ring network and the idea of face recognition system based on vehicle-mounted MOST networks is put forward.A face recognition node is added into the ring network,which is on the basis of MOST asynchronous communication that transmitting packet data via the I2 C bus,the frame boundary is modified to increase asynchronous bandwidth.The vehicle-mounted MOST camera and face recognition interface realizes the function of image acquisition,image information asynchronous transmission,identity authentication.Experiments show that the proposed method is operable and meet the actual demand.
