Abstract: The present disclosure provides an onboard screen casting system, an onboard screen casting method, and a computer-readable storage medium. The onboard screen casting system includes a host system and a virtual machine system; wherein, the virtual machine system is able to receive external bit stream data to be cast and transmit it to the host system; and the host system is able to decode the bit stream data into video stream data, and perform a visibility setting on the video stream data, to display the corresponding video.

Abstract: A vehicle navigation image synthesis method includes: acquiring M sampling images; storing N sampling images, a value of N being determined according to a speed of a target vehicle, a position of the target vehicle, and a following distance of the target vehicle; determining a plurality of sampling points of each sampling image of the N sampling images; determining first coordinates of each sampling point of the plurality of sampling points of each sampling image; mapping the first coordinates of each to the reference coordinate system to determine a second coordinate of each sampling point; and synthesizing sampling points of the N sampling images according to second coordinates of the sampling points of the N sampling images to determine a target image.
