Preset-pixel-based efficient cabin picture design method

The invention discloses a preset-pixel-based efficient cabin picture design method. The method is characterized in that the method includes the following steps: first an image processing software tool is utilized to generate a cabin picture of a corresponding resolution ratio and a picture image is stored; then according to the resolution ratio of the cabin picture and a picture display device scanning direction, the cabin picture is converted into a cabin picture character dot matrix; then according to a corresponding relation between pixel positions and pixel values, the character dot matrix is converted into a pixel value-pixel display position matrix table; and finally according to a display position of the cabin picture and the resolution ratio of the display device, corresponding pixel values on the pixel value-pixel position matrix table are filled to the corresponding pixel positions in a VRAM. The design method has a small workload and short development cycle, is easy to maintain, can change a previo
