Embodiment Construction

[0014] The specific embodiments of the present invention will be further described below in conjunction with the drawings.

[0015] An embodiment of a head-up display homologous circuit of the present invention

[0016] Such as figure 1 As shown, the homology circuit of the head-up display in this embodiment includes a symbol generation module, a display drive module, a CRT tube, and an image card connected in sequence, wherein the symbol generation module includes a vector generator and a D / A circuit unit, and the vector generator includes Character generation logic block and homology logic block. The output end of the character generation logic block is connected to the D / A circuit unit and the homology logic block respectively. The output end of the homology logic block is connected to the image card through the PCI_e bus, and the D / A circuit The output end of the unit is connected to the CRT tube through the display drive module. The working principle of this homologous circu...

Abstract

The invention relates to a head-up display and a method for realizing the homology thereof, and belongs to the technical field of airborne display equipment. In the present invention, the X and Y coordinate data generated by the symbol generation module in the head-up display are divided into two paths, one path generates a deflection signal through a DA conversion circuit, and together with the highlight signal, the character display is performed through a display drive module, and the other path X, Y coordinate data After processing, it is stored as a recorded picture, so that the picture data displayed in the head-up display and the recorded picture data are from the same source, ensuring that the recorded picture of the head-up display reflects the state of the head-up display in real time and truly.

Description

Technical field [0001] The invention relates to a head-up display and a method for realizing the same, belonging to the technical field of airborne display equipment. Background technique [0002] The head-up display accurately projects the symbols that need to be displayed into the driver’s front field of view, so that various information and real exterior information are superimposed, and these display symbols are generated by the symbol generation module and enlarged by the display drive module After processing, send it to CRT tube for display. [0003] In the early head-up display system, the cockpit camera was installed above the control panel directly in front of the head-up display, and was consistent with the optical axis of the head-up display. The recorded picture in any state is the picture physically superimposed on the head-up display and the exterior view taken by the cockpit camera, and the two are physically installed and corrected to ensure the same accuracy. In ...
