In an embodiment, as shown in fig. 2, fig. 2 is a flowchart of a display method of a vehicle-mounted display screen in an embodiment, and in this embodiment, a display method of a vehicle-mounted display screen is provided, and the display method of a vehicle-mounted display screen may be described by taking the vehicle-mounted display device 120 as an execution main body, and specifically may include the following steps:
step S210: and acquiring current light parameters outside the vehicle, wherein the light parameters comprise the light angle between the vehicle and natural light.
The light parameters may be used to describe state parameters of light currently coming from outside the vehicle, where the light from outside the vehicle may include natural light. The natural light may be sunlight from the sun or reflected light from the moon at night. In this step, the acquired light parameters may include a light angle between the vehicle and natural light. The light angle between the vehicle and the natural light is the irradiation angle of the natural light irradiating the vehicle, and the direction and the position of the natural light relative to the vehicle can be reflected.
Specifically, the step of acquiring the current light parameters outside the vehicle in step S210 may include:
s211: and acquiring the current real-time positioning information and the driving direction of the vehicle.
The vehicle may be mounted with a GPS (Global Positioning System) locator, the GPS locator is configured to detect a current position of the vehicle, and the GPS locator may generate Positioning information of the vehicle and determine a driving direction of the vehicle according to the current position of the vehicle. The on-vehicle display device can acquire the positioning information of the vehicle and the driving direction of the vehicle through the detection of the GPS positioner. The vehicle-mounted display device can read the positioning information and the data of the driving direction of the vehicle in the GPS positioner, and can also upload the positioning information and the data of the driving direction of the vehicle by the GPS positioner, and the vehicle-mounted display device calls the data.
S212: and determining the light angle between the vehicle and the natural light according to the positioning information and the driving direction.
In this step, the driving direction of the vehicle may be used to represent the direction of the head of the vehicle. In addition, in this embodiment, the determination manner of the light angle between the vehicle and the natural light may also be that the vehicle-mounted display device searches a record table in which the position of the natural light source in the area where the vehicle is located is recorded according to the positioning information, and determines the position of the natural light source in the record table according to the current time, that is, the position of the sun or the moon at the current time; and calculating the light angle between the vehicle and the natural light according to the driving direction of the vehicle and the direction of the natural light source. For example, the definition of the light angle of the light vehicle with the natural light may be described with reference to the traveling direction or the head direction of the vehicle, the orientation of the natural light source with respect to the vehicle may be calculated from the orientation of the natural light source, which may be represented by the orientation of the natural light source with respect to the vehicle, and the traveling direction or the head direction. The recording table of the directions of the natural light sources can record the directions of the natural light sources at various times, and the recording table can be stored in a memory of the vehicle-mounted display device or stored in a server and transmitted to the vehicle-mounted display device through the server.
Specifically, the solar azimuth angle and the solar altitude angle may be recorded in the recording table of the azimuth of the natural light source. Solar azimuth is the angle of the sun in azimuth, which is generally defined as the angle measured clockwise from north along the horizon; the solar altitude angle refers to an included angle between the incident direction of sunlight and the ground plane; the natural light source may be oriented by the sun azimuth and the sun altitude.
As shown in fig. 3, fig. 3 is a schematic diagram of light angles in an embodiment, where α and γ are a sun azimuth angle and a sun altitude angle, respectively, β is a driving direction of the vehicle, a difference between the driving direction β of the vehicle and the sun azimuth angle α is a relative azimuth angle θ of the sun with respect to the vehicle, an orientation of the natural light source with respect to the vehicle includes the relative azimuth angle θ and the sun altitude angle γ, and light angles of the vehicle with the natural light are orientations (i.e., θ and γ) of the natural light source with respect to the vehicle. Assuming that α is 40 ° north, β is 120 ° north, and γ is 40 ° in fig. 3, the relative azimuth angle θ of the sun with respect to the vehicle is 80 ° left of the traveling direction of the vehicle, and the elevation angle γ of the sun is 40 °.
When a recording table of the direction of the natural light source in the area where the vehicle is located is searched according to the positioning information, if the recording table is stored in a memory of the vehicle-mounted display equipment, the vehicle-mounted display equipment directly retrieves the recording table from the memory; if the record table is stored in the server, the vehicle-mounted display device requests the server and receives the record table, and the vehicle-mounted display device can access the network through the network interface and communicate with the server.
In the above manner of obtaining the light parameters, the direction of the natural light source relative to the vehicle can be determined by accurately obtaining the light angle between the vehicle and the natural light.

Specifically, the dynamic shadow may be constructed in the form of a halo representation, and the step of constructing the dynamic shadow according to the light parameters in step S220 may include:
s221: and determining a real-time halo central point on an interface of the vehicle-mounted display screen according to the light parameters.
The method is used for determining the position of the halo displayed on the vehicle-mounted display screen, and the coordinate of the halo central point in the vehicle-mounted display screen interface can be determined according to the light parameters.
For example, a preset mapping relationship exists between the light parameters and the coordinates of the halo central point, the mapping relationship can be used for calculating or searching the coordinates of the corresponding halo central point under the light parameters, and the obtained coordinates can determine the real-time halo central point on the vehicle-mounted display screen.
S222: and forming a special halo effect on the central point of the halo, and generating a dynamic shadow on the interface according to the special halo effect.
In the step, the special halo effect is loaded on a halo central point on an interface of the vehicle-mounted display screen, the rendering is carried out by taking the halo central point as a center, and the special halo effect forms dynamic shadow showing the brightness and the radiance of natural light on the interface.
The special halo effect can comprise a natural light source and a virtual image diffused from the edge of the light source; the method is used for showing the special effect of solar halo or the special effect of moon halo. In the using process, the halo special effect can be matched and selected according to the type of natural light, for example, the halo special effect can be selected when being used for displaying the sun halo special effect when the sun is on, and the halo special effect can also be correspondingly selected when being used for displaying the moon halo special effect when the moon is on. At some special time, in the morning or evening, the sun and the moon may appear in the sky at the same time, at the moment, the sun and the moon are respectively positioned in different directions in the air, and at the moment, the special effect of the sun halo and the special effect of the moon halo can be loaded on the interface of the vehicle-mounted display screen at the same time.

Furthermore, the real-time dynamic shadow can be constructed according to the light parameters acquired in real time, and a shadow layer generated by the real-time dynamic shadow can display the shadow which keeps synchronous with the shadow of the external environment of the vehicle. The vehicle-mounted display equipment regularly obtains and updates the light parameters at the current moment according to the preset interval time, constructs real-time dynamic shadow according to the light parameters, generates a shadow layer according to the real-time dynamic shadow, and displays the shadow layer on the interface of a vehicle-mounted display screen of a vehicle.
In addition, the dynamic shadow can be constructed by means of a special halo effect, and can also be constructed by means of a special light effect and the light angle between the vehicle and the natural light, the special light effect can comprise that the light with a specific direction is set according to the light angle between the vehicle and the natural light, and the special light effect can be used for showing sunlight light or moon bright light. The construction process of the light special effect comprises the following steps: firstly, determining a halo central point by the vehicle-mounted display equipment according to a light angle between a vehicle and natural light, then pointing the halo central point in an interface to the center of the interface as a specific direction, setting a light special effect according to the specific direction, and generating a dynamic shadow on the interface according to the light special effect.
Step S230: and displaying the light and shadow layer on an interface of a vehicle-mounted display screen of the vehicle.
In this step, the vehicle-mounted display screen can show the shadow effect of the external natural light of vehicle in real time through the shadow layer, and the driver and the passenger can feel the external environment of vehicle in the vehicle-mounted display screen in the vehicle. In addition, the light and shadow layer may be set in a background in an image displayed on the vehicle-mounted display screen, the background in the image displayed on the vehicle-mounted display screen may include the light and shadow layer, and when the vehicle-mounted display screen displays images of other operation interfaces, the vehicle-mounted display screen may also display the background in a superimposed manner on the basis of the images of the other operation interfaces, and at this time, the images of the other operation interfaces and the light and shadow layer may be displayed simultaneously.
By combining the display method of the vehicle-mounted display screen in the embodiment, the dynamic light and shadow can be constructed according to the current light parameters outside the vehicle, the dynamic light and shadow layer is generated by the dynamic light and shadow, and the light and shadow layer is displayed on the vehicle-mounted display screen; the vehicle-mounted display screen can display the light and shadow layers corresponding to the current vehicle-mounted environment in real time, the vehicle-mounted display screen can provide light and shadow effects adaptive to the current vehicle-mounted environment, various light and shadow layers can be provided along with different light parameters, and the display effects of the light and shadow layers in the vehicle-mounted display screen are rich; meanwhile, the display effect of the shadow layer can change along with the light parameters in real time, and the change of the display effect is fine and smooth.
Besides the display effect, the dynamic light shadow in the light shadow layer can reflect the direction of the current natural light source. Taking the dynamic shadow corresponding to the sunlight as an example, the dynamic shadow of the sunlight can enable a driver to sense the current direction of the sun through the vehicle-mounted display screen, and the dynamic shadow of the sunlight can help the driver to determine the basic directions of the south, the east, the west and the north and correct the direction sense of the driving process because the sun is generally in a relatively fixed direction in a specific area at a specific time.
As an example, in practical application, multiple display layers may be disposed in an interface of the vehicle-mounted display screen, and the interface may thereby obtain a display effect of a mixture of multiple layers.
In one embodiment, the display method of the vehicle-mounted display screen further comprises the following steps:
