Example one
Fig. 1 is a flowchart of a weather radar echo display method according to an embodiment of the present invention, where this embodiment is applicable to a case where acquired weather radar echo data is displayed in a three-dimensional image form, the method may be executed by a weather radar echo display device, the weather radar echo display device may be implemented by software and/or hardware, and the weather radar echo display device may be configured on a computing device, and specifically includes the following steps:
s101, acquiring echo data of the meteorological radar.
In the present embodiment, the meteorological radar is understood to be a radar specially used for atmospheric detection, which is one of the detection tools mainly used for warning and forecasting, and small-scale weather systems (such as typhoon and rainstorm clouds, etc.). The weather radar echo is understood to be electromagnetic wave data which is transmitted by the weather radar and is scattered by the atmosphere and suspended substances thereof and returned to be received by the radar antenna. The weather radar may be, for example, a weather Doppler radar operating in the 30-3000 MHz band, which is not limited in this respect by embodiments of the present invention.
Further, because there are raindrops, cloud drops, ice crystals, snow flakes, hail, dust and the very inhomogeneous air of refractive index distribution etc. in the atmosphere to make the composition of electromagnetic wave scattering, and to different precipitation systems, the meteorological radar echo has different characteristics, because there is relative displacement between the scattering element, the meteorological radar echo of being reflected by the scattering element has different phases, and these ripples are at radar antenna department superimposed result, have caused the random fluctuation of receiving the echo. The fluctuation parameters are analyzed, so that the motion information of the particles and the turbulence intensity of a meteorological radar measuring space can be obtained, and the echo data of the meteorological radar can be applied to the near weather forecast.
Specifically, echo data received by the meteorological radar antenna is obtained. Optionally, the echo data includes echo intensity and position information generated by the echo, where the position information includes altitude information used to characterize the position where the echo data is generated, and the altitude information may be understood as that electromagnetic waves transmitted by the radar at the altitude are scattered by some components in the atmosphere, so that an echo is generated and received by the radar antenna, that is, some substances affecting the weather may exist at the altitude.
And S102, determining color information corresponding to the spatial position coordinates in the preset spatial model according to the echo data.
In the present embodiment, the preset spatial model may be understood as a virtual model used to characterize the meteorological radar detection space in the three-dimensional scene. Optionally, the preset space model may be a cube model.
Specifically, the echo data are mapped into a preset space model in an equal proportion according to the position information in the echo data, so that the echo data correspond to points corresponding to space position coordinates in the preset space model one by one, and the color information corresponding to the space position coordinates in the preset space model is determined according to the echo intensity in the echo data corresponding to the space position coordinates and based on the corresponding relation between the preset echo intensity and the color. Furthermore, the corresponding relation between the echo intensity and the color can be given through a preset transformation function, so that the echo intensity can be corresponding to one gradient color band to acquire color values corresponding to different radar intensities.
S103, determining corresponding light rays of the first pixel points in the preset space model and projection coordinate points on the screen according to the preset observation point position information and the space position coordinates of the first pixel points in the display surface of the preset space model.
The screen is located between the preset observation point and the preset space model.
In the present embodiment, the preset observation point may be understood as a point where a human eye, a camera, or the like is assumed to observe the preset spatial model through the screen in advance. The display surface of the predetermined spatial model may be understood as a visible area on the predetermined spatial model which is visible from a predetermined viewpoint through the screen. The first pixel point can be understood as each pixel point constituting the visible region on the preset spatial model. The ray can be understood as a ray that passes through the first pixel point and passes through the predetermined spatial model with the predetermined viewpoint as the vertex. The projection coordinate point can be understood as an intersection point of a connecting line of the preset observation point and the first pixel point and the screen.
Specifically, for any first pixel point on the display surface of the preset space model, according to a preset observation point space position coordinate in the preset observation point position information and a first pixel point space position coordinate corresponding to the first pixel point, a connection line between the preset observation point and the first pixel point is determined, the connection line extends towards the inside of the preset space model through the first pixel point in the connection line extending direction, and rays which penetrate through the preset space model and are obtained through extension are determined as light corresponding to the first pixel point. And determining the intersection point as a projection coordinate point of the first pixel point projected on the screen according to the intersection point of the connection line of the preset observation point and the first pixel point and the screen, and determining the coordinate information of the intersection point on the screen as the coordinate information of the projection coordinate point.
In the embodiment of the invention, the corresponding light of the first pixel point in the space model is determined according to the preset observation point position information and the space position coordinate of the first pixel point on the display surface in the preset space model, the echo data of each point on the light of the first pixel point can be further determined, the possibility of selecting the echo data which is more suitable for being displayed on the display surface of the preset space model is further provided, and the problem that the generated display result is not in line with the expectation due to the fact that only the peripheral data can be colored and displayed when the three-dimensional image is displayed is avoided.
S104, determining the spatial position coordinates of the second pixel points meeting the preset echo condition in each light ray, and displaying color information corresponding to the spatial position coordinates of the second pixel points as the color of the first pixel points on the projection coordinate points corresponding to the first pixel points.
In this embodiment, the preset echo condition may be a condition for screening the echo intensity in the echo data, which is determined according to the user requirement. For example, when the near weather is predicted, a strong echo area in the weather radar echo and a focus point thereon need to be paid more attention, the preset echo condition may be set to be the maximum echo intensity, so as to highlight a display area of the maximum radar echo intensity in the three-dimensional space, and the preset echo condition may be preset before displaying, which is not limited in the embodiment of the present invention.
Specifically, the method includes the steps of determining the echo intensity meeting a preset echo condition in each echo intensity according to the echo intensity of echo data corresponding to each pixel point in each light ray, determining the pixel point corresponding to the echo intensity as a second pixel point in the light ray, determining corresponding color information of the second pixel point in a preset space model according to a space position coordinate of the second pixel point, taking a color corresponding to the color information as a color of a first pixel point corresponding to the second pixel point, and displaying the color on a projection coordinate point of the first pixel point on a screen. Further, when the projection coordinate points corresponding to all the first pixel points display the determined color, the rendered weather radar echo data can be displayed in a three-dimensional mode on the screen.
Further, although the method for three-dimensionally displaying weather radar echo data provided in the embodiment of the present invention uses triangle one-sided drawing to render weather radar echoes through an open graphic library method to realize the display of three-dimensional graphics thereof in the prior art, the method can only perform coloring display on peripheral data of radar echo surfaces of different height layers, and it is difficult to obtain a display result meeting the demand of an approaching weather forecast.
According to the technical scheme of the embodiment, the echo data of the meteorological radar is obtained; determining color information corresponding to the spatial position coordinates in the preset spatial model according to the echo data; determining corresponding light rays of the first pixel points in the preset space model and projection coordinate points on a screen according to the preset observation point position information and the space position coordinates of the first pixel points in the display surface of the preset space model; the screen is positioned between a preset observation point and a preset space model; and determining the spatial position coordinates of the second pixel points which meet the preset echo condition in each light ray, and displaying the color information corresponding to the spatial position coordinates of the second pixel points as the color of the first pixel points on the projection coordinate points corresponding to the first pixel points. By adopting the technical scheme, the acquired echo data of the meteorological radar is mapped to the preset space model, light passing through each pixel point is determined according to the preset observation point position information and each first pixel point in the display surface of the preset space model, the projection coordinate of each first pixel point on the screen for displaying the meteorological radar echo intensity is determined, the second pixel point meeting the preset echo condition in the light corresponding to each first pixel point is determined, the color corresponding to the color information determined according to the echo data of the second pixel point is displayed on the projection coordinate corresponding to the first pixel point, so that a user can acquire the important and prominent meteorological radar echo information on the screen for displaying the meteorological radar echo intensity, and the meteorological radar echo information is displayed by using the three-dimensional image. The problem of meteorological radar echo data show under two-dimensional space image, directly perceived inadequately is solved to make and can obtain outstanding show with the meteorological radar echo data in that the three-dimensional image carries out the show key information, improved the practicality and the accuracy of meteorological radar echo in the application of weather forecast of closing on.
Example two
Fig. 2 is a flowchart of a weather radar echo display method according to a second embodiment of the present invention, which is further optimized based on the above optional technical solutions, and by converting echo data collected by a weather radar into a gray scale image with a corresponding height, and then the echo data is mapped to the preset space model according to the gray-scale map, so that the computing performance of the computer display card is better utilized, the computing efficiency is improved, determining the corresponding light of the first pixel points in the preset space model according to the preset observation point position and each first pixel point in the preset space model display surface, and then confirm the display colour of first pixel on the screen through the echo data in the light for key information can obtain outstanding show in the meteorological radar echo data that carries out the show with three-dimensional image, has improved the practicality and the accuracy of the three-dimensional image that carries out the show in the screen. The method specifically comprises the following steps:
s201, acquiring echo data of the meteorological radar.
S202, height information in the echo data is obtained.
Specifically, the acquired echo data of the weather radar includes echo intensity and position information of where an echo is generated, and the position information includes height information of a position where the echo is generated and plane position coordinate information of the echo generated in the height plane.
And S203, determining echo data with the same height in the echo data according to the height information, and generating a gray-scale map corresponding to the height according to the echo data with the same height.
In the present embodiment, the Gray Scale Image (Gray Scale Image) may be understood as an Image expressed by Gray Scale, wherein the Gray Scale may be understood as several levels obtained by dividing the white color and the black color according to a logarithmic relationship, and the Gray Scale may be specifically divided into 256 steps. Further, the gray scale values in the gray scale map may form a corresponding relationship with the data intensity, and the like, and may be used to characterize the data intensity at different points.

For example, for each echo data in the detection range received by the weather radar antenna, the echo data may be grouped at intervals of 50 meters to form a gray scale map corresponding to the fault data at the height, where the fault data is the echo data at the same height, that is, when the height range of the echo data acquired by the weather radar is 250 meters to 6750 meters from the ground, the fault data may be understood as data at a height level 300 meters, 350 meters, 500 meters from the ground, and the gray scale map generation does not need to be performed on the echo data between 300 and 350 meters, and the resolution of the gray scale map may be 512 by 512, and may also be set according to an actual situation, which is not limited in this embodiment of the present invention. The gray value of the gray map and the echo intensity in the echo data have a mapping relation, and if the range of the echo intensity is 0-70, the range is mapped to the gray value range of 0-255, so that the gray value corresponding to each point on the gray map is determined.

Specifically, when the subsequent image rendering processing is performed, processing preparation needs to be performed once for each image, so that when the number of generated gray-scale images is more than one, the gray-scale images can be grouped, and the gray-scale images in each group are spliced into one gray-scale image, so as to reduce the number of times of processing preparation, wherein the splicing of the gray-scale images in each group can be completed according to the height sequence corresponding to each gray-scale image. For example, assuming that the number of the grayscale images is 128 and the resolution is 512 × 512, the grayscale images may be divided into two groups, and the grayscale images in the groups are merged according to the height information corresponding to the grayscale images in the groups and according to a preset height merging condition, where the preset height merging condition may be a low-to-high merging condition, so that the grayscale images generate two grayscale images with a resolution of 4096 × 4096, where the specific grouping condition and the resolution of the grayscale images generated in each group are related to the current data processing upper limit, which is not limited in this embodiment of the present invention.
In the embodiment of the invention, the echo data acquired by the meteorological radar is converted into the gray-scale image according to the height information, the calculation performance of the computer display card is utilized, and the method has better data processing performance and processing efficiency compared with the method of completely using the CPU of the computer for calculation, and meanwhile, a plurality of gray-scale images are spliced into a larger image and then transmitted to the computer display card, so that the data transmission times are reduced, the data reading times of the display card are reduced, the calculation speed and the response performance are improved, and the processing efficiency aiming at the same number of echo data is improved.

Further, fig. 3 is a flowchart illustrating a process of determining color information corresponding to spatial position coordinates in a preset spatial model according to each gray scale map and echo data according to an embodiment of the present invention, which specifically includes the following steps:
s2041, scaling each gray scale image according to the size of the preset space model.
Specifically, the size of each gray scale image is scaled according to the size of the plane size of the preset space model, so that the position of the plane coordinate point in each gray scale image corresponds to the plane coordinate in the preset space model.
S2042, mapping each gray scale image and the echo data corresponding to each gray scale image to a preset space model according to the height corresponding to each gray scale image, and determining the echo data corresponding to each space position coordinate in the preset space model.
Specifically, determining the gray level maps with the highest and lowest heights according to the heights corresponding to the gray level maps, mapping the gray level maps and the echo data corresponding to the gray level maps to the top and the bottom of the preset space model respectively, mapping the rest gray level maps and the echo data corresponding to the gray level maps to the preset space model according to the corresponding heights and the height proportion determined according to the highest and lowest gray level maps, namely determining the data corresponding to a plurality of data layers in the preset space model, and determining the echo data corresponding to the spatial position coordinates of the unmapped gray level maps in the preset space model by an interpolation method according to the echo data corresponding to the gray level maps of the height layers.
