Reversing image starting method and system and vehicle

The invention provides a reversing image starting method and system and a vehicle. The reversing image starting method and system are applied to the vehicle carrying a host of an Android system and adistributed real-time operation (QNX) system, and the host comprises a display screen. The method comprises the following steps: receiving first target image data; performing resolution adaptation conversion on the first target image data to obtain second target image data; when it is determined that the Android system is in an unstarted state, starting a reversing image layer corresponding to thedistributed real-time operating system; and sending the second target image data to the display screen through a reversing image layer corresponding to the distributed real-time operating system. Thestarting time of the QNX system is basically maintained at about 3 seconds, so that the reversing image can be loaded when a driver sits in a main driving position, and the reversing image can be displayed when the driver perf
