Preset-pixel-based efficient cabin picture design method

Abstract

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 previous single mode of thinking which can only be realized through codes, and achieves an effect of ''seeing upon designing''; and operation time of a CPU is substantially saved, operation performance of the CPU is improved, and a requirement for real-time display of the onboard cabin picture is satisfied.

Description

technical field [0001] The invention belongs to the field of embedded airborne display systems, and in particular relates to an efficient cockpit picture design method. Background technique [0002] With the rapid development of modern aircraft technology, the integrated display of the screen is an inevitable trend. Airborne graphic display is the core of the new generation of avionics systems to achieve integration, digitization and intelligence. Improving the quality of graphic display and accelerating the speed of graphic generation are the key factors for airborne graphics. Show system key. When the picture is real-time and clear, the pilot can ensure that the pilot can operate in time and accurately. The picture refresh speed must be at least faster than the frame memory refresh speed to achieve dynamic real-time display of the picture. Starting from the hardware structure and graphics generation algorithm of the graphics display system, applying mature software and ha...

Problems solved by technology

It can be seen that the problems in the development of modern cockpit display lie in the cumbersome manual process, time-consuming, poor interactivity, and heavy dependence on specific equipment (that is, in the absence of hardware platform support, it is impossible to verify whether the screen design meets the requirements)
