The invention provides an automobile data recorder and a method for realizing augmented reality navigation. The automobile data recorder comprises a camera, a digital signal processor, a controller local area network interface, a micro-control unit and a transmission module. The digital signal processor comprises an image signal processor module, an augmented reality creating module and an encoding module. The camera is used for collecting an environment image; the image signal processor module is used for carrying out image processing on the environment image to generate a processed environment image; the micro-control unit is used for receiving navigation information from an infotainment system host of the vehicle through the CAN interface; the augmented reality creating module is used for superposing the processed environment image and navigation information to generate augmented reality navigation data; the coding module is used for coding the augmented reality navigation data; and the transmission module is used for transmitting the encoded augmented reality navigation data to a display instrument. According to the invention, the hardware design cost can be saved, and the overall delay of the system is reduced.

    本发明提供了一种行车记录仪和用于实现增强现实导航的方法。行车记录仪包括摄像头、数字信号处理器、控制器局域网络接口、微控制单元和传输模块。数字信号处理器包括图像信号处理器模块、增强现实创建模块和编码模块。摄像头用于采集环境图像;图像信号处理器模块用于对环境图像进行图像处理,生成经处理的环境图像;微控制单元用于经由CAN接口从车辆的信息娱乐系统主机接收导航信息;增强现实创建模块用于对经处理的环境图像和导航信息进行叠加,生成增强现实导航数据;编码模块用于对增强现实导航数据进行编码;以及传输模块用于将经编码的增强现实导航数据传输至显示仪表。本发明能够节约硬件设计成本,降低系统的整体延时。
