All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
Fig. 1 is a schematic flow chart of a method for three-dimensional dynamic display of wind according to an embodiment of the present invention, as shown in fig. 1, including: s1, acquiring data to be displayed; the data to be displayed comprises wind speed data, wind direction data and three-dimensional coordinate data of each data point in the area to be displayed at the initial moment; s2, arranging an initial two-dimensional vector field according to the data to be displayed, and acquiring at least one predicted two-dimensional vector field corresponding to the initial two-dimensional vector field according to the wind speed data, the wind direction data and the display duration; the display duration comprises at least one display moment, and each display moment corresponds to one predicted two-dimensional vector field; s3, according to the three-dimensional coordinate data, three-dimensionally mapping the initial two-dimensional vector field and the predicted two-dimensional vector field to obtain an initial three-dimensional vector field corresponding to the initial two-dimensional vector field and a predicted three-dimensional vector field corresponding to the predicted two-dimensional vector field; and S4, sequentially displaying the three-dimensional models respectively corresponding to the initial three-dimensional vector field and the predicted three-dimensional vector field according to the sequence of each display time in the display duration.
Wherein, a vector field (also called vector field) is a function of one vector corresponding to another vector; vector fields are widely used in physics, and common vector fields include wind fields, gravitational fields, electromagnetic fields, water flow fields, and the like. The vector field in the embodiments of the present invention is a vector field describing wind.
In step S1, the data to be displayed is wind data collected at a certain time in a certain area, and the data includes wind direction data, wind speed data and coordinate data of data points collected at a plurality of points in the area; the coordinate data is three-dimensional data, and as shown in fig. 2, may be acquired by a Geographic Information System (Geographic Information System or Geo-Information System, GIS).
In step S2, arranging an initial two-dimensional vector field corresponding to the data to be shown obtained in step S1; the two-dimensional vector field describes the wind speed and wind direction of each data point in the area from the angle of a two-dimensional plane; moreover, because the dynamic change condition of the wind needs to be displayed, a display duration is set, and the display process is to display the dynamic state of the wind within the display duration; displaying a two-dimensional vector field corresponding to the initial moment in the duration as an initial two-dimensional vector field; the display duration further comprises at least one display moment after the initial moment, and the two-dimensional vector field corresponding to the display moment is a predicted two-dimensional vector field; the predicted two-dimensional vector field is obtained by specifically performing prediction calculation on the position of wind by using an initial two-dimensional vector field and a prediction moment.
In step S3, three-dimensional vector fields respectively corresponding to the two-dimensional vector fields are obtained by mapping the two-dimensional coordinate system to the three-dimensional coordinate system according to the initial two-dimensional vector field and the at least one predicted two-dimensional vector field obtained in step S2.
In step S4, the initial three-dimensional vector field and the predicted three-dimensional vector field obtained from step S3; and displaying the models respectively corresponding to the three-dimensional vector fields. For example, the preset time period is 10 seconds, wherein 1 second, 2 seconds to 10 seconds respectively correspond to one three-dimensional model; then, during display, displaying the three-dimensional model corresponding to the initial three-dimensional vector field in the 0 th second, displaying the predicted three-dimensional model with the display time of 1 second in the 1 st second, and displaying the predicted three-dimensional model with the display time of 2 seconds until the predicted three-dimensional model with the display time of 10 seconds in the 10 th second; through the sequential display of the three-dimensional models, the three-dimensional dynamic display of wind is realized.
According to the three-dimensional dynamic wind display method provided by the embodiment of the invention, the two-dimensional vector field is generated according to the data to be displayed, the prediction calculation is carried out in the two-dimensional vector field, and the corresponding three-dimensional vector field is obtained through three-dimensional mapping, so that the data calculation in the three-dimensional vector field is avoided, a three-dimensional model can be rapidly generated, the performance consumption of equipment is reduced, and the application range of the three-dimensional dynamic wind display method is widened.
On the basis of any of the above embodiments, the step S2 specifically includes: s21, arranging an initial two-dimensional vector field corresponding to the data to be displayed according to the wind speed data, the wind direction data and the longitude and latitude data in the three-dimensional coordinates of each data point in the data to be displayed; s22, selecting at least one data point in the initial two-dimensional vector field, taking the position of each selected data point as an initial generation position, and generating a corresponding wind factor; the wind factor is used for representing the dynamic change of wind; and S23, calculating the position of the wind factor at the display moment according to the time interval between the display moment and the initial moment, the wind speed data and the wind direction data of the data point where the wind factor is located, and acquiring a predicted two-dimensional vector field corresponding to the display moment.
In step S21, an initial two-dimensional vector field is arranged; specifically, longitude and latitude data in three-dimensional coordinates, namely two-dimensional coordinate information on the earth plane, are selected, the position of each data point is determined, and then wind direction data and wind speed data are marked for the data points, so that an initial two-dimensional vector field is established.
In step S22, generating a wind factor according to the initial two-dimensional vector field established in step S21; the wind factor is an expression object and a carrier of wind, and the dynamic change condition of the wind (including parameters reflecting the wind, such as wind speed, wind direction, wind intensity, position and the like) in the vector field is expressed by the change of the wind factor; the wind factor may be generated randomly in the initial two-dimensional vector field, that is, one or more data points are randomly selected, and each data point generates a wind factor.
In step S23, according to the wind factor generated in step S22, a time variable needs to be added to the wind factor, that is, a display duration and at least one display time included in the display duration are given. For example, for a wind factor, the position of the wind factor at the 1 st second can be calculated by assigning a time variable of 1 second according to the wind speed and wind direction of the data point at the initial generation position; and marking the wind factor at the position in the initial two-dimensional vector field to obtain a two-dimensional vector field, namely the predicted two-dimensional vector field corresponding to the 1 st second display moment. For the 2 nd second predicted two-dimensional vector field, prediction is also performed based on the above calculation method.
Based on the above steps S21 to S23, the prediction of the wind direction in the two-dimensional vector field can be realized, and the dynamic change of the wind can be reflected by the wind factor.
On the basis of any of the above embodiments, the step S3 specifically includes: and respectively mapping each data point to a three-dimensional coordinate system according to the elevation data in the three-dimensional coordinates of each data point in the initial two-dimensional vector field and the predicted two-dimensional vector field to obtain the initial three-dimensional vector field corresponding to the initial two-dimensional vector field and the predicted three-dimensional vector field corresponding to the predicted two-dimensional vector field.
Specifically, in step S3, since the two-dimensional vector field is constructed based on the longitude and latitude coordinates in the three-dimensional coordinates; therefore, after the initial two-dimensional vector field and the at least one predicted two-dimensional vector field are generated, height direction data is given to each data point according to elevation data in a three-dimensional coordinate in each data point in the two-dimensional vector field, two-dimensional to three-dimensional mapping is achieved, and therefore the three-dimensional vector field is obtained.
On the basis of any of the above embodiments, the step S21 is further followed by: and adding supplementary data points in the initial two-dimensional vector field, and acquiring wind speed data and wind direction data of the supplementary data points through interpolation according to data points near the supplementary data points.
In particular, as the data points contained in the data to be displayed may be fewer, the formed two-dimensional vector field is not detailed enough, so that the description of the wind in the area is not accurate enough; therefore, supplementary data points can be added at any position where data point supplement is needed, and wind speed data and wind direction data of the supplementary data points are obtained through interpolation, so that completion of the initial two-dimensional vector field is completed, and display precision is improved.
On the basis of any of the above embodiments, the step of obtaining the wind speed data and the wind direction data of the supplementary data point by interpolation according to the data point near the supplementary data point specifically includes: and respectively interpolating the wind direction data and the wind speed data by a bilinear interpolation method according to the wind speed data and the wind direction data of four data points around the supplementary data point to obtain the wind speed data and the wind direction data of the supplementary data point.
The bilinear interpolation is also called as bilinear interpolation, is linear interpolation expansion of an interpolation function with two variables, and has the core idea of performing linear interpolation in two directions respectively.
Specifically, each data point has two variables, namely wind speed data and wind direction data, so that the wind speed data and the wind direction data of the supplementary data points can be acquired by a bilinear interpolation method; specifically, the wind direction data and the wind speed data are obtained by respectively interpolating the wind direction data and the wind speed data of four data points near the supplementary data point.
On the basis of any of the above embodiments, the step S22 further includes: in the initial two-dimensional vector field, calculating the duration of the wind factor according to the wind speed data of the data point of the initial generation position of the wind factor; accordingly, the value of the presentation time duration is the duration of the wind factor or a default value.
Specifically, the duration of the wind factor is the life cycle of the wind factor, and is specifically obtained from the wind speed data of the data point at the initial generation position of the wind factor (the wind speed is positively correlated with the intensity of the wind, and the duration of the wind is longer as the wind speed is higher). The duration reflects when the wind disappears, and therefore, the duration for which the entire dynamic presentation process lasts, i.e., the presentation duration, can be set to correspond to the duration of the wind factor. For example an initial two-dimensional vector field comprising wind factors of 3, 4 and 5 minutes duration, respectively, the presentation duration of which may be set to 3 or 4 or 5 minutes; likewise, the presentation time period may also be set to 10 minutes by default.
On the basis of any of the above embodiments, the step of generating the corresponding wind factor in S22 specifically includes: adding a wind factor identifier at an initial generation position; the wind factor identification comprises a picture and/or a color, and is determined by wind speed data and wind direction data of a data point corresponding to the wind factor.
In particular, the wind factor acts as a carrier for representing the wind, which needs to be embodied by adding pictures and/or colors, such as pictures of the wind or arrows. The pictures and the colors can be determined by wind speed data and wind direction data of data points corresponding to the positions, and pictures with larger sizes or deeper colors can be formed when the wind speed is higher; the direction of the arrow should also be the same as the wind direction.
On the basis of any of the above embodiments, the step S4 further includes: and respectively coloring the initial three-dimensional vector field and the predicted three-dimensional vector field to obtain corresponding three-dimensional models.
In particular, the three-dimensional vector field may be colored, thereby obtaining a visualized three-dimensional model. For example, for the virtual reality technology, a three-dimensional vector field may be subjected to virtual reality processing such as trailing rendering, a three-dimensional flow effect is generated, and a three-dimensional model of the virtual reality is obtained for VR presentation.
It should be noted that, during the display, besides sequentially displaying the three-dimensional models respectively corresponding to the initial three-dimensional vector field and the predicted three-dimensional vector field in sequence, the display can also be set as a circular play; after the three-dimensional model corresponding to the predicted three-dimensional vector field at the last display moment is displayed, returning to display the three-dimensional model corresponding to the initial three-dimensional vector field, and circulating.
