The invention relates to the technical field of projection equipment, in particular to a projection method and device of a vehicle-mounted projector, and the method comprises the steps: detecting the actual distance between a picture bearing medium and a vehicle or the vehicle-mounted projector; the optimal focus and the optimal size of a projection picture of the vehicle-mounted projector are matched according to the actual distance; and according to the focus and the size of the projection picture, projecting the vehicle machine screen picture of the vehicle or the projection screen picture of the mobile terminal of the user to a picture bearing medium. Therefore, the technical problems that the inclination angle of the vehicle-mounted projector cannot be automatically adjusted, the manual operation cost is increased, the use convenience of a user is reduced, the intelligent level of a vehicle is low, and the entertainment requirement of the user cannot be met in the related technology are solved.
本申请涉及投影设备技术领域,特别涉及一种车载投影仪的投影方法及装置,其中,方法包括:检测画面承载介质距离汽车或者车载投影仪的实际距离;根据实际距离匹配车载投影仪的投影画面的最佳聚焦和最佳大小;按照投影画面的聚焦和大小将汽车的车机屏幕画面或者用户的移动终端投屏画面投影至画面承载介质上。由此,解决了相关技术中无法自动调节车载投影仪的倾斜角度,增加了人力操作成本,降低了用户使用的便捷性,车辆的智能化水平较低,无法满足用户的娱乐需求的技术问题。
