Detailed Description
Reference will now be made in detail to embodiments of the present invention, examples of which are illustrated in the accompanying drawings, wherein like or similar reference numerals refer to the same or similar elements or elements having the same or similar function throughout. The embodiments described below with reference to the drawings are illustrative and intended to be illustrative of the invention and are not to be construed as limiting the invention.
The following describes a vehicle-mounted holographic display method and apparatus according to an embodiment of the present invention with reference to the drawings.
Fig. 1 is a schematic flow chart of a vehicle-mounted holographic display method according to an embodiment of the present invention. The embodiment provides a vehicle-mounted holographic display method, wherein an execution main body is a vehicle-mounted holographic display device, and the execution main body is composed of hardware and/or software. The vehicle-mounted holographic display method apparatus may specifically be a hardware device, such as a terminal device, a backend server, or the like, or software or an application installed on the hardware device.
As shown in fig. 1, the vehicle-mounted holographic display method includes the following steps:
and S101, responding to the image playing instruction, and acquiring the current running state of the vehicle.
In this embodiment, the image playing instruction may be a trigger signal input by a user, and the image playing instruction is used to instruct holographic imaging to be performed on a front windshield of a vehicle to establish a vehicle-mounted holographic cinema. For example, the user inputs an image playing command through an image playing key arranged on the vehicle, or the user inputs the image playing command through a virtual button of a human-computer interaction interface of the touch vehicle, or the user inputs the image playing command by voice, but not limited thereto.
In this embodiment, the vehicle-mounted holographic display device obtains the current driving state of the vehicle when receiving the response image playing instruction, where the current driving state of the vehicle is a driving state and a parking state. The in-vehicle holographic display device may determine the current driving state of the vehicle by a built-in GPS (Global Positioning System) or a speed sensor, or may communicate with an ECU (Electronic Control Unit) of the vehicle to acquire the current driving state of the vehicle from the ECU, but the present invention is not limited thereto.
And S102, determining a projection mode of the holographic projection equipment according to the current running state.
Specifically, the holographic projection technology breaks through the traditional sound, light and electricity limitations, the space imaging color is bright, the contrast and the definition are very high, the space sense and the perspective sense are very strong, the image presents a super-vivid three-dimensional effect, and vivid visual impact and good viewing experience are provided for audiences.
In this embodiment, a holographic projection technique based on a holographic film is used. The principle of the holographic projection technology based on the holographic film is Peltier's phantom, and the holographic projection technology has two working modes, wherein one mode is a rear projection mode, namely, an image is directly projected on the holographic film; the other is reflective, i.e. the image is projected onto the holographic film in reflection. More details on the Peltier phantom are described in the related art. Holographic projection technology based on holographic films relies on holographic films as projection media, and large-scale commercialization has been achieved with a lower cost advantage. The embodiment applies the holographic projection technology based on the holographic film to the vehicle, can realize the construction of the vehicle-mounted cinema with lower cost, and improves the film watching experience of users.
In this embodiment, the projection mode of the holographic projection device is divided into a full-screen projection mode and a half-screen projection mode. When the vehicle is in a driving state, the holographic image cannot be presented on the front windshield corresponding to the main driver, the sight line of the driver is prevented from being influenced, and safe driving is guaranteed. When the vehicle is in a parking state, in order to improve the viewing experience, the holographic image can be presented on all or most of the front windshield, and at this time, the projection mode of the holographic projection device is a full screen projection mode.
For example, when the user is in a suburb or in a self-driving tour at night, the user can start the full-screen projection mode to watch the holographic film after stopping the vehicle, so that the user can have a pleasant film watching feeling in an outdoor situation. When the vehicle has other passengers besides the fingerprint of the driver, the half-screen projection mode can be started to enable the passengers in the front and rear rows to watch the holographic film in the driving process of the vehicle, and meanwhile, the sight line of the driver is not affected.
And S103, forming a viewing area corresponding to the projection mode on a front windshield of the vehicle.
In this embodiment, the projection modes are different, and the viewing zones formed on the front windshield are also different. Specifically, the premise of forming a viewing zone on a front windshield requires a holographic film on the front windshield of a vehicle, and the viewing zone is formed by controlling the front windshield in different areas covered by the holographic film. If the front windshield is provided with the holographic film, the viewing area can be formed by the holographic film; if the front windshield is not provided with the holographic film, the holographic film is attached to the inner surface of the front windshield of the vehicle, or the holographic film on the front windshield is controlled to be unfolded and retracted through a lifting device.
It should be noted that, when the holographic film on the front windshield is controlled to be unfolded and retracted by the lifting device, the holographic film may be a transflective holographic film. The semi-transparent semi-reflective holographic film can enable a user to view clear holographic images, and can enable the user to see scenery outside the automobile without influencing light rays inside the automobile.
In this embodiment, when the projection mode is the half-screen projection mode, the viewing area is the entire area or a partial area of the front windshield facing the front passenger car. For example, a lifting device is arranged on the front windshield facing the rider-driving, the lifting device can control the first holographic film to expand and retract, and when the projection mode is a half-screen projection mode, the lifting device controls the first holographic film to expand to cover a first windshield area, wherein the first windshield area belongs to at least one part of the front windshield corresponding to the rider-driving.
In this embodiment, the projection mode is a full screen projection mode, and the viewing area is a whole area or a partial area of the front windshield. For example, a lifting device is arranged on the front windshield opposite to the rider and can control the first holographic film to expand and retract, and a lifting device is arranged on the front windshield opposite to the rider and can control the second holographic film to expand and retract; when the projection mode is a full screen projection mode, the first holographic film is unfolded and covers the first windshield area, and the second holographic film is unfolded and covers the second windshield area; the first windshield area belongs to at least one part of front windshield corresponding to the copilot, and the second windshield area belongs to at least one part of front windshield corresponding to the main driver; and taking a windshield area formed by the first windshield area and the second windshield area as a viewing area corresponding to the full-screen projection mode.
Further, in order to improve the comfort of passengers on the passenger seat, the inclination angle of the seat back corresponding to the passenger seat is adjusted to the preset inclination angle. Wherein, the preset inclination angle is set according to the actual situation.
And S104, holographically projecting the image data to be played to the viewing area through the holographically projecting equipment.
In this embodiment, the holographic projection device may be any existing device that can reproduce a real three-dimensional image of an object. When an image playing instruction input by a user is received, the vehicle-mounted holographic display device controls the holographic projection equipment to holographically project image data to be played to a viewing area so as to establish a vehicle-mounted holographic cinema.
According to the vehicle-mounted holographic display method provided by the embodiment of the invention, the current driving state of the vehicle is obtained by responding to the image playing instruction; determining a projection mode of the holographic projection equipment according to the current driving state; forming a viewing area corresponding to the projection mode on a front windshield of the vehicle; and holographically projecting the image data to be played to the viewing area through the holographically projecting equipment. Therefore, the vehicle-mounted holographic cinema can be established without investing large cost, and the entertainment performance of the vehicle and the viewing experience of a user are improved.
