The invention relates to a holographic projection system and method for a vehicle, a computer medium and a vehicle with a holographic logo. The invention relates to the technical field of vehicle external display. The system comprises a light source device, a beam expanding lens, a collimating lens and a holographic sheet, the light source device emits a light beam to the beam expanding lens, the beam expanding lens expands the laser beam emitted by the light source device into an area light source, the area light source subjected to strong beam expanding by the collimating lens is collimated into parallel light beams, all the light beams enter the holographic sheet at a specific angle, and the holographic sheet records a graph to be displayed in the holographic sheet in a holographic camera shooting mode. A virtual image is formed. The device is simple in structure, additional equipment such as a rainwater storage structure, a water mist generation device and a recovery device does not need to be additionally arranged, water mist is needed as an imaging carrier of projection images in the implementation scheme, so that a series of devices such as water mist generation devices are needed, and the projection images cannot be observed once the water amount is insufficient due to the influence of the water amount.
本发明是一种用于车辆的全息投影系统、方法、计算机介质、带有全息车标的车辆。本发明涉及车辆外部显示技术领域,所述系统包括:光源器件、扩束透镜、准直透镜和全息片;所述光源器件射出光束至扩束透镜,扩束透镜将光源器件发射的激光束扩束成面光源,所述准直透镜强扩束后的面光源准直为平行光束,使光束全部以特定角度入射全息片,所述全息片将待显示图形通过全息摄像的方式记录在全息片中,形成虚像。本发明结构简单:无需加装雨水储存结构、水雾产生装置、回收装置等附加设备,该实现方案需要水雾作为投影像的成像载体,因此需要有水雾产生等一系列装置,同时受水量影响,一旦水量不足,将无法观察到投影像。
