Detailed Description
In order to make the objects, technical solutions and advantages of the embodiments of the present disclosure more clear, the technical solutions of the embodiments of the present disclosure will be described below in detail and completely with reference to the accompanying drawings of the embodiments of the present disclosure. It is to be understood that the embodiments described are only a few embodiments of the present disclosure, and not all embodiments. All other embodiments, which can be derived by a person skilled in the art from the described embodiments of the disclosure without any inventive step, are within the scope of protection of the disclosure.
The present disclosure provides a weather data presentation method and a Virtual Reality device in a Virtual Reality (VR) environment. With the development of VR technology, it is increasingly applied to various fields. The embodiment of the disclosure provides a more intuitive and flexible meteorological data observation experience compared with a two-dimensional presentation mode in a traditional real environment by presenting meteorological data in a three-dimensional form in a selected three-dimensional geographic area in a virtual reality environment.
FIG. 1 shows a schematic flow diagram of a method of weather data presentation in a virtual reality environment, according to an embodiment of the present disclosure.
In step S101, map data and weather data are acquired. For example, the meteorological data can be acquired from a meteorological data station in real time or acquired in a preset period; the map data may be acquired based on a Geographic Information System (GIS).
In step S102, a selection of a three-dimensional geographic area is received. For example, the user's selection of a three-dimensional geographic area may be obtained by way of human-computer interaction. As an example, the user' S selection of a three-dimensional geographic area may be obtained by the following steps S1021 and S1022:
in step S1021, a three-dimensional space model is generated based on the map data. The three-dimensional space model comprises a map, a geographical area position option and a geographical area altitude option.
The map data obtained from the GIS-based system may include longitude, latitude, etc. information, on the basis of which a map may be built. The division of the geographic area on the map can be selected according to needs, for example, the division can be divided according to administrative areas, such as Beijing, Shanghai, Guangzhou and the like, and the division can be further finely divided according to longitude and latitude. The geographic area location option is for the user to select a location of the geographic area and the geographic area altitude option is for the user to select an altitude of the geographic area.
In step S1022, a three-dimensional space model is presented in the virtual reality environment.
The map may be presented in two or three dimensions, at the bottom of a three dimensional space.
The geographic area location options may be presented in a variety of ways, such as by marking different geographic areas on the map by color, line, or other means for selection by the user, presenting a list of geographic areas above the map or other location for selection by the user, providing latitude and longitude options for more refined area selection, and so forth.
The geographical region altitude option may also be presented in various ways, such as in the form of a menu through which a user may select one or more altitude layers; or may take the form of an altitude scale on which the user selects one or more altitudes by selecting a scale.
In step S1023, a user selection of a location and altitude of a three-dimensional geographic area is received. A three-dimensional geographic area may be characterized by a location and an altitude. For example, the user may first select a geographic location on the map, such as beijing, and then select an altitude via an altitude scale, where the altitude may be selected as one or more discrete values, or may be a range, such as 100m, or may be selected as 1000 m. Then beijing + altitude 100-. User selection of a three-dimensional geographic area may be received via any feasible input means, such as a joystick, buttons, or the like.
In addition to the location and elevation of the geographic area, it may be provided to enable the user to select the type of meteorological data to be presented. For example, a meteorological data type option may also be provided when presenting a three-dimensional spatial model, and the user may select the meteorological data type via a joystick, button, or the like. Types of meteorological data include, but are not limited to, temperature, humidity, barometric pressure, wind speed, and the like.
In step S103, meteorological data within the selected three-dimensional geographic area is extracted. For example, for the three-dimensional geographic area characterized by Beijing + elevation 100-.
At step S104, meteorological data within the selected three-dimensional geographic area is presented in three dimensions in the virtual reality environment.
For example, the three-dimensional presentation of the weather data may be realized by the following steps S1041 to S1042.
In step S1041, a three-dimensional data model is established based on the extracted meteorological data. The three-dimensional data model includes meteorological data values and their corresponding longitudes, latitudes and altitudes. Also for the example of beijing, for example (116 ° 30 '27 "for east longitude, 39 ° 54' 27" for north latitude, 100m for altitude, 40% for humidity value) constitutes a data point, and humidity values in the entire beijing range at 100m for altitude constitute a data distribution layer. In practical applications, the acquisition of the meteorological data acquired in step S101 is not spatially continuous, and for example, in the range of 100-1000m, there may be only 100m, 200m, 300m … … at altitudes. The three-dimensional data model constructed in this step is also composed of discrete layers.
In step S1042, the three-dimensional data model is rendered in the virtual reality environment. As an example, the presentation may be superimposed in an already presented three-dimensional space containing a map.
FIG. 4A shows an example effect diagram of the weather data presentation of this embodiment. As shown in fig. 4A, a three-dimensional meteorological data model is presented above the map 10, meteorological data is presented in the form of a plurality of height layers 20 arranged vertically, each height layer 20 corresponds to one or a group of altitudes, the abscissa and ordinate of each height layer 20 represent longitude and latitude, and the varying color of each height layer 20 (fig. 4A is a black-and-white diagram, so it is represented by gradation, and various colors can be used as required in practical applications) represents meteorological data values. Optionally, the height scale 30 may also be displayed superimposed on the side of the height layer for ease of viewing and selection.
FIG. 2 shows a schematic flow diagram of a method for weather data presentation in a virtual reality environment, according to another embodiment of the present disclosure. This embodiment is similar to the method of FIG. 1, except at least that interpolation is performed to supplement the meteorological data values when rendering the three-dimensional data model, and the viewing corridor is rendered according to the user's selection.
In step S101, map data and weather data are acquired. For example, the meteorological data can be acquired from a meteorological data station in real time or acquired in a preset period; the map data may be acquired based on a Geographic Information System (GIS).
In step S102, a selection of a three-dimensional geographic area is received. For example, the user's selection of a three-dimensional geographic area may be obtained by way of human-computer interaction. As an example, the user' S selection of a three-dimensional geographic area may be obtained by the following steps S1021 and S1022:
in step S1021, a three-dimensional space model is generated based on the map data. The three-dimensional space model comprises a map, a geographical area position option and a geographical area altitude option.
The map data obtained from the GIS-based system may include longitude, latitude, etc. information, on the basis of which a map may be built. The division of the geographic area on the map can be selected according to needs, for example, the division can be divided according to administrative areas, such as Beijing, Shanghai, Guangzhou and the like, and the division can be further finely divided according to longitude and latitude. The geographic area location option is for the user to select a location of the geographic area and the geographic area altitude option is for the user to select an altitude of the geographic area.
In step S1022, a three-dimensional space model is presented in the virtual reality environment.
The map may be presented in two or three dimensions, at the bottom of a three dimensional space.
The geographic area location options may be presented in a variety of ways, such as by marking different geographic areas on the map by color, line, or other means for selection by the user, presenting a list of geographic areas above the map or other location for selection by the user, providing latitude and longitude options for more refined area selection, and so forth.
The geographical region altitude option may also be presented in various ways, such as in the form of a menu through which a user may select one or more altitude layers; or may take the form of an altitude scale on which the user selects one or more altitudes by selecting a scale.
In step S1023, a user selection of a location and altitude of a three-dimensional geographic area is received. A three-dimensional geographic area may be characterized by a location and an altitude. For example, the user may first select a geographic location on the map, such as beijing, and then select an altitude via an altitude scale, where the altitude may be selected as one or more discrete values, or may be a range, such as 100m, or may be selected as 1000 m. Then beijing + altitude 100-. User selection of a three-dimensional geographic area may be received via any feasible input means, such as a joystick, buttons, or the like.
In addition to the location and elevation of the geographic area, it may be provided to enable the user to select the type of meteorological data to be presented. For example, a meteorological data type option may also be provided when presenting a three-dimensional spatial model, and the user may select the meteorological data type via a joystick, button, or the like. Types of meteorological data include, but are not limited to, temperature, humidity, barometric pressure, wind speed, and the like.
In step S103, meteorological data within the selected three-dimensional geographic area is extracted. For example, for the three-dimensional geographic area characterized by Beijing + elevation 100-.
At step S204, meteorological data within the selected three-dimensional geographic area is presented in three dimensions in the virtual reality environment.
For example, the three-dimensional presentation of the weather data may be realized by the following steps S2041 to S2045.
In step S2041, a three-dimensional data model is built from the extracted meteorological data. The three-dimensional data model includes meteorological data values and their corresponding longitudes, latitudes and altitudes. Also for the example of beijing, for example (116 ° 30 '27 "for east longitude, 39 ° 54' 27" for north latitude, 100m for altitude, 40% for humidity value) constitutes a data point, and humidity values in the entire beijing range at 100m for altitude constitute a data distribution layer. In practical applications, the acquisition of the meteorological data acquired in step S101 is not spatially continuous, and for example, in the range of 100-1000m, there may be only 100m, 200m, 300m … … at altitudes. The three-dimensional data model constructed in this step is also composed of discrete layers.
In step S2042, the meteorological data values are supplemented by interpolation calculation for positions in the three-dimensional data model for which there is no corresponding meteorological data. For example, for the above example, a height region between altitudes of 100m and 200m has no temperature data, then the temperature data between 100m and 200m may be supplemented with existing meteorological data by interpolation. As another example, if the area between geographic area a and geographic area B does not have corresponding temperature data, the interpolation may also be performed using the temperature data of the existing geographic area. It is also preferable to take geographical and environmental factors into account in the interpolation, for example, to use different interpolation methods for mountains and plains, to make the supplementary meteorological data as accurate as possible.
In step S2043, the three-dimensional data model is rendered in a virtual reality environment. As an example, the presentation may be superimposed in an already presented three-dimensional space containing a map. FIG. 4B illustrates an example effect diagram of the weather data presentation of this embodiment. As shown in fig. 4B, a three-dimensional meteorological data model is presented above the map 10, meteorological data is presented in the form of a plurality of altitude layers 21 arranged vertically, each altitude layer 21 corresponds to one or a group of altitudes, surface relief of each altitude layer 21 represents a set of altitudes of corresponding points of all meteorological data points of the layer in three-dimensional space, abscissa and ordinate of each altitude layer 21 represent longitude and latitude, and color change of each altitude layer 21 represents meteorological data values. Through the interpolation of step S2042, the meteorological data is presented in the form of a plurality of successive height layers 21, and each height layer 21 is presented in the form of a successive layer.
Unlike the embodiment of FIG. 1, in this embodiment, an observation channel 40 is also presented when presenting the three-dimensional weather digital-analog model to allow a user to enter the model to observe weather data. As shown in fig. 4B, the viewing channel 40 cuts through and extends through the plurality of height layers 21. The number of viewing channels 40, the cutting position and the cutting direction may be preset or may be set by the user. For example, a viewing corridor setting option may be presented when presenting the three-dimensional meteorological data model, and the user may set the number of viewing corridors, the cutting positions, and the cutting directions according to the option.
In step S2044, a movement designation is received. For example, the user may enter movement instructions through a joystick, buttons, or otherwise.
In step S2045, the rendering angle of view may be moved along the viewing channel according to the movement instruction. As can be seen in fig. 4B, by providing the viewing channel 40 and moving the viewing angle according to the user's movement instruction, the user can be visually provided with the experience of entering the inside of the model to view data.
