Therefore, the projection position of the multimedia image is related to the specific installation position of the light projection system. For example, the light projection system may be installed in a headlamp on one side or in headlamps on both sides, and the light projection system in the headlamp may project the multimedia image on a road surface or a facade in front of the vehicle. Similarly, the light projection system can be installed in the tail light on one side or two sides, and can project the multimedia image on the road surface or the vertical surface behind the vehicle. The light projection system can be arranged in the reflectors on one side or two sides and can project the multimedia images on the road surface or the elevation on the side surface of the vehicle. The light projection system can be arranged on the vehicle body on one side or two sides and can project the multimedia images on the road surface or the elevation on the side surface of the vehicle. The light projection system can be arranged in the vehicle and can project the multimedia images on the side windshield or the rear windshield of the vehicle. Of course, the specific installation position is not limited to this, and can be adjusted according to actual needs. Of course, the light projection systems can be installed at the same time at the installation positions, so as to project different or the same multimedia images at different positions around the vehicle and different positions of the vehicle.
In some embodiments, the usage scenario of the multimedia image projection car light is as follows:
in a scene 1, when a user carries out outdoor Party, the user triggers a headlamp to project a music video or a network video which is prepared in advance on a wall or the ground by triggering a video projection function button.
In the scene 2, as shown in fig. 5, the user sets the birthday of the lover as a specific date in advance, and sets a blessing message and a special effect image in accordance with the specific date. When the vehicle is unlocked or started on the birthday day, the preset blessing words and the special effect images are displayed in a projection mode to carry out birthday blessing.
And in a scene 3, a user edits and sets a unique signature image of the user in advance, and when the vehicle is unlocked or started each time, the signature lasting for a fixed time is projected to welcome the user and identify the identity of the user.

The display time of the multimedia image can be freely set, for example, the multimedia image automatically disappears after being displayed for 5 seconds.
It should be noted that the multimedia images are all actually projected on the road surface, and the relative positions of the multimedia images are fixed along with the lane lines, so that the multimedia images are like icons actually existing on the road surface, but not suspended in the virtual effect of the road surface or the air, and have strong driving experience and visual impact.
As shown in fig. 2, in an embodiment of the projection system of multimedia images of the present invention, the interactive control system includes an information acquisition unit, an interactive control unit and an image output unit; the information acquisition unit is used for acquiring the driving state data of the vehicle and the triggering state of the video projection function; and/or a triggering state of a body light show function; and/or a trigger state of a user signature function; the interactive control unit calls a video based on the state data transmitted by the information acquisition unit; and/or date-specific greeting images; and/or a user signature image; the image output unit is used for outputting the video; and/or date-specific greeting images; and/or transmitting the user signature image to the light projection system.
Specifically, the driving state data of the vehicle includes a vehicle speed and a shift position, and can be extracted from an ECU (Electronic Control Unit) of the vehicle through an in-vehicle communication bus, and if the vehicle speed is 0 and the shift position is a parking position, the interactive Control Unit determines that the vehicle is in a parking static state, that is, a non-driving state; the triggering state of the video projection function means whether the video projection function is started or not, and can be extracted from an ECU of a vehicle through an in-vehicle communication bus, specifically, the triggering state is obtained from the ECU of a central control or an ECU of a control key, for example, a user triggers a video projection enabling switch on the central control, the central control ECU captures corresponding operation and sends information to a vehicle body bus, and an information acquisition unit of the system extracts the information from the bus so as to know whether the user triggers the starting of the function or not. The video projection function can be triggered by pressing a 'video projection function button'; if the interactive control unit judges that the vehicle is in a non-driving state and triggers the video projection function, calling a video pre-stored by the central control system, or a video of an external memory or a network video from the Internet of vehicles, and sending the video to the light projection system by the image output unit; if the vehicle speed is not 0 or the gear is not in the parking gear, the driving state of the vehicle is judged, and the video is not suitable to be played at the moment so as to avoid causing traffic accidents due to interference on driving, so that the interactive control unit cannot call any video.
Specifically, the triggering state of the vehicle body light show function is whether the light show function is turned on or not, and can be extracted from a central control ECU or an ECU of a control key through an in-vehicle communication bus, the light show triggering signal can be triggered when unlocking, ignition, flameout or locking, if the interaction control unit judges that the light show function is turned on according to the triggering state of the vehicle body light show function sent by the acquisition unit, whether the current day is a preset specific date or not is continuously judged, the specific date comprises a legal holiday and an exclusive memorial day set by a user, the exclusive memorial day comprises a birthday, a marriage memorial day and the like, if the specific date is, a greeting image corresponding to the specific date is called, and as shown in fig. 5, the birthday blessing image comprises characters of 'happy birthday' and an auxiliary special effect balloon icon and the like. Preferably, the interactive control system further comprises a sensing unit, wherein the sensing unit is used for detecting whether obstacles influencing projection exist on a road surface in front of the vehicle, the obstacles comprise vehicles, pedestrians, ground marks and other projection icons occupying the display area, the projection effect is influenced when the obstacles exist, and the projection is not required.
Specifically, the triggering state of the user signature function refers to whether the user signature function is started or not, and can be extracted from a central control ECU (electronic control unit) or an ECU (electronic control unit) of a control key through an in-vehicle communication bus, the user signature function has two triggering modes, one mode is used as a part of a light show, the signature of a user is displayed when the light show is triggered, and if the signature of the user is displayed in a welcome light show, the personalized customization function is displayed; another is a manual button trigger, such as a user may trigger by clicking a "user signature function button". If the interaction control unit judges that the user signature function is started according to the trigger state of the user signature function sent by the acquisition unit, the corresponding user signature image is called.
At the same time, one, two or all of the three functions of video projection, special date greeting and user signature can be activated, and the functions can be flexibly selected according to specific use scenes.
