The invention relates to a projection structure, which comprises a light source, a film part, a lens group, a motor and a sensor module, the film part is located between the light source and the lens group and comprises a plurality of projection patterns, and the projection patterns can at least partially transmit light from the light source; the lens group comprises at least one lens and is used for projecting at least part of transmission light rays from the film part so as to project a projection pattern on a projection surface; the motor can drive the film part to rotate for continuous projection; the film part further comprises a plurality of identification codes, and the identification codes are in one-to-one correspondence with the projection patterns and used for indicating position information of the corresponding projection patterns; the arrangement interval of the plurality of identification codes is the same as the arrangement interval of the plurality of projection patterns; the sensor module can detect information related to the identification code, and the information can uniquely determine the position of the identification code. The invention further relates to a projection method, a medium and a vehicle.
本发明涉及一种投影结构,包括光源、胶片部、透镜组、电机和传感器模块,其中:光源可朝向胶片部发射光线;胶片部位于光源和透镜组之间,包括多个投影图案,投影图案可至少部分地透射来自光源的光线;透镜组包括至少一个透镜,对来自胶片部的至少部分透射光线进行投射,以将投影图案投射在投影表面;电机可带动胶片部旋转以进行连续投影;胶片部还包括多个识别码,识别码与投影图案一一对应,用于指示对应投影图案的位置信息;多个识别码的布置间隔与多个投影图案的布置间隔相同;传感器模块可检测与识别码相关的信息,信息可唯一地确定识别码的位置。本发明还涉及一种投影方法、介质和车辆。
