The invention relates to the technical field of head-up display, in particular to an HUD optical aberration correction method, system and device and a vehicle. The correction method comprises the following steps: generating a light beam through an LED light source or a laser light source, and adjusting the brightness and color parameters of the LED light source or the laser light source through a control circuit so as to adapt to different display requirements and environmental conditions; and the light beam is preliminarily shaped and collimated by the light beam shaping element until a proper divergence angle and a proper light spot size are met so as to meet the requirements of a coupling element. According to the invention, the light beam emitted by the light machine is subjected to one-dimensional or two-dimensional pupil expansion through the optical waveguide, and then view field expansion and aberration correction are carried out through the free-form surface mirror, so that the problems of large size, limited view field angle, small eye box range and insufficient imaging definition in the prior art are effectively solved.
本发明涉及抬头显示技术领域,具体为一种HUD光学像差矫正方法、系统、装置及车辆。所述校正方法的步骤包括:通过LED光源或激光光源产生光束,并通过控制电路调整所述LED光源或激光光源的亮度、颜色参数以适应不同的显示需求和环境条件;所述光束经过光束整形元件进行初步的整形和准直,直至满足合适的发散角和光斑尺寸,以适应耦合元件的要求。本发明通过将光机发出的光束经过光波导进行一维或二维扩瞳,再通过自由曲面镜进行视场扩展和像差矫正,有效解决了现有技术中体积大、视场角受限、眼盒范围小和成像清晰度不足的问题。
