摘要: A display method for a display assembly, a display system, and a display device of a vehicle column A, and a storage medium. According to the display method, by means of a conversion relationship between a coordinate system of a target feature model and a camera coordinate system of a driver monitoring assembly and a conversion relationship between the coordinate system of the target feature model and a world coordinate system, a conversion relationship between the camera coordinate system and the world coordinate system is obtained, a coordinate of the display assembly in the world coordinate system can be converted into a coordinate in the camera coordinate system, and thus whether a driver watches the display assembly can be simply determined. The problem that it is difficult to determine, directly according to the eyes of the driver and a spatial position of the display assembly, whether the driver watches the display assembly is solved, and the effect of reducing the difficulty of determining whether the driver watches the display assembly is achieved.
