Claim 7:
8. A display device for A-pillars of a vehicle, comprising a processor and a memory storing at least one instruction, at least one program, a code set or an instruction set therein; wherein the processor, when loading and executing the at least one instruction, the at least one program, the code set or the instruction set, is caused to perform a display method for A-pillar-mounted display assemblies of a vehicle, the method comprising:
establishing a world coordinate system;
acquiring a target image of a target feature model in the vehicle by any one driver monitoring assembly of at least one driver monitoring assembly;
determining a second conversion relationship between coordinates in the target feature model and coordinates in a camera coordinate system of the any one driver monitoring assembly based on the target image of the target feature model;
acquiring a third conversion relationship between the coordinates in the target feature model and coordinates in the world coordinate system;
determining a first conversion relationship based on the third conversion relationship and the second conversion relationship;
acquiring facial posture information of a driver of the vehicle in the camera coordinate system by any one driver monitoring assembly of the at least one driver monitoring assembly, wherein the facial posture information comprises a gaze direction of the driver and an eye position of the driver;
determining a visual field of the driver based on the gaze direction of the driver and the eye position of the driver;
acquiring coordinates of the two display assemblies in the world coordinate system;
converting the coordinates of the two display assemblies in the world coordinate system into coordinates in the camera coordinate system based on the first conversion relationship;
determining, based on the coordinates of the two display assemblies in the camera coordinate system, whether any one display assembly of the two display assemblies is within the visual field; and
capturing, based on the eye position of the driver, an external image of the vehicle captured by the imaging assembly in response to the any one display assembly being within the visual field, and displaying the captured image on the any one display assembly.
