The invention discloses a method for quickly displaying a reversing video by an Android vehicle machine system. The method comprises the following steps: S100, powering on the Android vehicle machinesystem, and starting an Android system cold machine; S200, loading a bootloader program of a vehicle-mounted processor, guiding the bootloader program, initializing a controller related to the displayof the Android system through the bootloader program, and guiding kernel programs of the Android system and the linux system through the bootloader program; S300, after the linux system is started, loading a reversing video application program; after the Android kernel is started, starting a JAVA virtual machine, and operating an Android application program; S400, using a Linux system applicationprogram to continuously detect whether a reversing signal exists or not, and when the reversing signal is detected, executing a step S500; and S500, acquiring camera video data through a Linux system, and displaying the acquired camera video data on a display screen of the Android vehicle machine. Compared with the prior art in which rapid reversing video display is realized through two modes ofhardware and software, the method has the advantages of low cost, more flexible realization, high reversing video display speed and the like.
一种Android车机系统快速显示倒车视频的方法,包括:S100给Android车机系统上电,Android系统冷机启动;S200加载车载处理器的引导程序,并引导bootloader程序,通过bootloader程序初始化Android系统显示相关的控制器,通过bootloader程序引导Android系统和linux系统的内核程序;S300 linux系统启动完成,加载倒车视频应用程序;Android内核启动完成,启动JAVA虚拟机,运行Android应用程序;S400 Linux系统应用程序不断检测是否有倒车信号,当检测到倒车信号时,执行S500;S500通过Linux系统获取摄像头视频数据,并将获取的摄像头视频数据显示到Android车机的显示屏上。本发明相较于现有技术中通过硬件和软件两种方式实现快速倒车视频显示,具有成本低、实现更加灵活,显示倒车视频的速度快等优势。
