The current time is subject to the system time of the electronic device. The weather data can be acquired from a network/cloud in real time so as to improve the accuracy of the weather data; the system time may also be periodically and cyclically obtained from the network/cloud, for example, once per hour, to reduce power consumption of the electronic device.
The weather data comprises weather data corresponding to the current time and/or weather data corresponding to the future preset time. The weather data corresponding to the future preset time comprises the following steps: weather data corresponding to a plurality of hours in the future and/or weather data corresponding to a plurality of days in the future. Whether the weather data corresponds to the current time or the weather data corresponds to the future preset time, the weather data comprises temperature, weather states, wind power information, precipitation information, other weather information and the like.
The weather conditions include, but are not limited to, sunny days, cloudy days, haze, showers, light rains, heavy rains, thunderstorms, sleets, small snows, heavy snows, hailstones, sand storms, and the like.

The three-dimensional weather model may be a static three-dimensional model or may be a dynamic three-dimensional model. For example, for light rain weather, the three-dimensional weather model may include a static model corresponding to light rain and dark clouds, and may also be a dynamic model corresponding to light rain and slow moving dark clouds which are dripping down. The weather data can be displayed more intuitively and clearly through the three-dimensional model.
For the same weather condition, a plurality of different three-dimensional weather models can be set according to different current times, for example, weather is also cloudy, the corresponding three-dimensional clouds show bright white in the morning, and the three-dimensional clouds show the color of sunset in the evening.
The weather audio and video data corresponding to the weather data can be weather audio data or weather video data. For example, for thunderstorm weather, in addition to displaying the three-dimensional weather model corresponding to the thunderstorm weather, audio data of the thunderstorm weather can be played, or animation of the thunderstorm weather, namely weather video data, can be played. The weather condition corresponding to the target user can be displayed and reminded more intuitively through the weather audio-video data.
Through three-dimensional weather model and weather audio and video data, through visual show and audio and video show promptly, improved the bandwagon show's bandwagon effect, also improved the warning effect that weather was reminded, increased the interest that weather was reminded.
In an embodiment, the step of determining the three-dimensional weather model and the weather audio/video data corresponding to the weather data according to the current time includes: determining a time period to which the current time belongs; determining a corresponding three-dimensional weather model from a weather display library according to the weather data and the time period; and determining corresponding weather audio-video data from a weather audio-video database according to the weather data and the time period. According to the embodiment, the three-dimensional weather model and the weather audio and video data corresponding to the weather data are determined according to the time period of the current time, so that the three-dimensional weather model and the weather audio and video data corresponding to the weather data do not need to be determined in real time, the operation efficiency is improved, and the power consumption of electronic equipment (a projector) is reduced.
Wherein, the time periods are divided into early morning, afternoon, dusk, night and the like according to the current time. The time period corresponding to morning can be set to 5:00-7:00, the time period corresponding to morning can be set to 7: 00-12: 30, the time period set in afternoon can be set to 12:30-16:30, the time period corresponding to evening can be set to 16:30-19:00, the time period corresponding to night can be set to 19:00-5:00, and the like.
The corresponding time periods described above are merely illustrative for easier understanding of the aspects in the embodiments of the present disclosure. The time period can also be set to other more or fewer time periods, and can also be set to different time periods according to different seasons; the time range corresponding to each time period may also be set to other time ranges, or may also be set to different time ranges according to different seasons, and so on.
And after the time period of the current time is determined, determining a corresponding three-dimensional weather model from the weather display library according to the weather data and the time period. And respectively determining the three-dimensional weather models corresponding to the current weather data and the future weather data from the weather display library according to the current weather data, the future weather data and the corresponding time periods in the weather data. The weather display library stores various weather data and different three-dimensional weather models corresponding to different time periods.
The method comprises the following steps of determining a three-dimensional weather model corresponding to future weather data from a weather display library according to the future weather data and a corresponding time period, wherein the steps comprise: determining a future time period corresponding to the future weather data according to the time corresponding to the future weather data and the corresponding time period; and determining a three-dimensional weather model matched with the future time period and the future weather data from the corresponding three-dimensional weather model in the weather display library according to the future time period and the future weather data.
The three-dimensional weather model including the three-dimensional model corresponding to the weather condition is taken as an example for explanation. For example, if the determined time period is 11:00 am and the current weather condition in the weather data is sunny day, determining that the current corresponding three-dimensional weather model is a three-dimensional sun; determining that the corresponding three-dimensional weather model is a three-dimensional sun if the future time period corresponding to one hour in the future is the morning and the corresponding weather condition is sunny, determining that the corresponding three-dimensional weather model is a three-dimensional white cloud if the future time period corresponding to two hours in the future is the afternoon and the corresponding weather condition is cloudy; and if the weather data of the future day is light rain, determining that the corresponding three-dimensional weather model is a three-dimensional model of light rain plus dark clouds.
In the embodiment, the three-dimensional weather models corresponding to the current weather data and the future weather data are determined according to the three-dimensional models of the same display type, such as three-dimensional static models.
In an embodiment, current weather data and future weather data may be respectively presented using three-dimensional weather models of different presentation types. Correspondingly, the step of determining the three-dimensional weather model corresponding to the weather data from the display library according to the weather data and the time period comprises the following steps: determining a three-dimensional weather model of a first display type from a weather display library according to current weather data and a time period in the weather data; and determining the three-dimensional weather model of the second display type from the weather display library according to the future weather data in the weather data and the time period. The first display type is determined according to the current weather data, and the second display type is determined according to the future weather data. The first display type can be a three-dimensional dynamic model, and the second display type can be a three-dimensional static model, so as to highlight the display effect corresponding to the current weather data.
The display type can be determined according to a static model and a dynamic model, and can also be determined according to a three-dimensional weather model and a non-three-dimensional weather model. For example, in one embodiment, the first display type is a three-dimensional weather model, and the second display type is a non-three-dimensional weather model, such as a two-dimensional weather model, so as to reduce the amount of computation corresponding to the projection display. The determination may also be performed according to other manners, for example, in an embodiment, the three-dimensional weather model corresponding to the first display type is determined according to a time period, for example, if the current time is evening and the weather condition is cloudy, the three-dimensional cloud is displayed in the color of sunset; the three-dimensional weather model corresponding to the second display type corresponds to a universal three-dimensional weather model, whether clouds are in the evening or in the morning is not considered, and if the clouds are in the morning, the clouds are uniformly displayed as three-dimensional white clouds. In an embodiment, the three-dimensional weather model corresponding to the first presentation type may be a three-dimensional model including more weather information in addition to the weather condition, and the three-dimensional weather model corresponding to the second presentation type is a three-dimensional model including only the weather condition.
The step of determining the corresponding weather audio/video data from the weather audio/video database according to the weather data and the time period comprises the following steps: and determining weather audio and video data matched with the weather data and the time period from a weather audio and video database according to the weather data and the time period. The weather audio and video database comprises different weather data and weather audio and video data corresponding to different time periods. In this embodiment, each weather data and time slot in the weather data are matched with corresponding weather audio-video data.
For example, if the time period is early morning and the current weather data is sunny, determining that the weather audio/video data matched with the current weather data and the time period is audio/video data including bird sings from the weather audio/video database. For example, if the time period is early morning and the current weather data is lightning weather, determining that the weather audio and video data matched with the current weather data and the time period is audio and video data including lightning thunder from a weather audio and video database. The weather data are displayed and reminded through the weather audio and video data, so that the display effect and the reminding effect of the weather data are improved.
The weather audio and video data corresponding to the current weather data and the time period can be played by default, and the weather audio and video data corresponding to the future weather data are not played by default, so that confusion of a target user is avoided. And for the condition that the weather data only comprises the future weather data, default playing the weather audio-video data corresponding to the time closest to the current time in the future weather data. For example, only the future weather data is displayed on a certain interface to be displayed, the current weather data is not displayed, when the interface to be displayed is opened/refreshed, only the corresponding future weather data is acquired, and the weather audio/video data corresponding to the time closest to the current time in the future weather data can be correspondingly played. Assuming that the future weather data comprises weather data of a future day and weather data of two future days; correspondingly, weather audio and video data corresponding to the weather data of the future day are played.
In other embodiments, the corresponding weather audio-video data can be determined according to the weather data corresponding to the current focusing position in the projected and displayed interface to be displayed. For example, the interface to be displayed in projection display includes both current weather data and future weather data, but if the current focusing position is the weather data corresponding to one hour in the future, the corresponding weather audio/video data is determined according to the weather data corresponding to one hour in the future. The current focusing position can be determined by the position in the interface to be displayed touched/clicked by the target user (such as remote control click).
In an embodiment, the step of determining the corresponding weather audio/video data from the weather audio/video database according to the weather data and the time slot includes: when the weather data comprises current weather data, determining weather audio and video data matched with the current weather data and the time period from a weather audio and video database according to the current weather data and the time period in the weather data; and when the weather data only comprises the future weather data, determining the corresponding weather audio-video data from the weather audio-video database according to the time nearest to the current time in the future weather data and the future weather data corresponding to the time. In the embodiment, only one piece of weather data is determined from the weather data, and the corresponding weather audio and video data is determined according to the determined weather data and the time period, so that the calculation amount is reduced.
In the step, the three-dimensional weather model and the weather audio and video data corresponding to the weather data are determined according to the current time, namely, the display effect of the weather display is improved according to the visual display and audio and video display modes, meanwhile, the reminding effect of the weather reminding is also improved, and the interestingness of the weather reminding is increased.
