Multi-screen projection method, storage medium, electronic equipment and vehicle-mounted multi-screen projection system

The invention provides a multi-screen projection method, a storage medium, an electronic device and a vehicle-mounted multi-screen projection system.The multi-screen projection method comprises the steps that a projected screen converts and displays coordinates and sizes of all display objects on a projection screen according to a first formula: x2 = (wt/w) * x1 + x, y2 = (ht/h) * y1 + y; w2 = (wt/w) * w1; h2 = (ht/h) * h1; x1, y1, w1 and h1 are the left vertex abscissa, the left vertex ordinate, the transverse length and the longitudinal length of any display object of the projection screen respectively, and x2, y2, w2 and h2 are the left vertex abscissa, the left vertex ordinate, the transverse length and the longitudinal length of a projection area distributed on the projected screen by the corresponding display object respectively. The method is low in cost. 本发明提供一种多屏投射方法、存储介质、电子设备及车载多屏投射系统，所述多屏投射方法，包括：所述被投射屏幕按下述公式一对投射屏幕上的所有显示对象的坐标和尺寸进行变换和显示，公式一：x2=(wt/w)*x1+x；y2=(ht/h)*y1+y；w2=(wt/w)*w1；h2=(ht/h)*h1；x1、y
