In order to solve the problems in the background art, the embodiment of the application provides a rendering method of a flight path, wherein a rendering device of the flight path determines a driving track of a target flight path according to acquired data of the target flight path, each position in the data is converted into a position in a spherical coordinate system, then the rendering device of the flight path renders the driving track according to the position in the spherical coordinate system to obtain a rendered track, and therefore the rendering method of the flight path is simple, data processing is smooth, and the effect of the rendered track is improved.

The following detailed description of embodiments of the present application refers to the accompanying drawings.

Fig. 1 is a schematic flowchart of a rendering method of a flight path provided in an embodiment of the present application, and as shown in fig. 1, the rendering method includes:

s101, the rendering device of the route acquires data of a target route.

Wherein the data includes a start position, an end position, and intermediate parameters including at least one of a maximum altitude, a minimum altitude, and a unit distance traveled.

It should be noted that the intermediate parameter includes at least one of a maximum height, a minimum height, and a unit travel distance, and may be that the intermediate parameter includes only the maximum height, only the minimum height, or only the unit travel distance; the intermediate parameters may include any two or three of the maximum height, the minimum height and the unit travel distance, and may be specifically set according to the needs, and are not limited herein.

It should be noted that the target route includes an air flight route and a water flight route. Such as the flight path of an aircraft in the air, the travel path of a submarine in the sea.

Illustratively, the target flight path is a flight path of the aircraft in the air, for example, the target flight path is a flight path of the aircraft in a time period of 10:00-12:00(24 hours), in the flight path, the data of the target flight path includes a starting position of the position at 10:00, an ending position of the position at 12:00, a maximum altitude of the maximum altitude of all altitudes of the aircraft from the ground during the flight of the aircraft in the time period of 10:00-12:00, a minimum altitude of the minimum altitude of all altitudes of the aircraft from the ground during the flight of the aircraft in the time period of 10:00-12:00, and the unit driving distance is the mileage of the flight path of the aircraft in the time period of 10:00-12: 00.

And S102, determining the driving track of the target route by the rendering device of the route according to the data.

For example, the target route may be a curve or a straight line. The curve may be a parabola, for example. Meanwhile, the determined driving track can be a curve or a straight line, namely, the target route corresponds to the driving track.

For example, taking the target route as the flight route of the aircraft in the air as an example, the route rendering device may calculate, according to the data of the target route and according to a preset period, information (for example, coordinates of each position and the height of the aircraft from the ground at the current time) corresponding to each position of the aircraft on the flight route, so as to obtain the driving track of the target route.

For example, the preset period may be 1 minute (min), or 5 minutes (min), and may also be 10 seconds(s), and the embodiment of the present application is not limited. It should be noted that the shorter the preset period is, the more accurate the obtained driving track of the target route is.

And S103, the rendering device of the flight path converts the coordinate system of each position in the data to obtain the position of each position in the spherical coordinate system.

Specifically, in the data of the target route, the starting position and the ending position are positions (i.e., longitude and latitude coordinates) in a geographic coordinate system, and all the longitude and latitude coordinates in the data are converted into positions in a spherical coordinate system, i.e., spherical coordinates.

Illustratively, as shown in fig. 2, a spherical coordinate system with a radius R is established, and it is assumed that the horizontal rotation angle of the target route is θ (0, 2 pi), and the up-down rotation angle is

In the spherical coordinates shown in figure 2,

as a point of action, i.e. angle of rotation theta and of M

The dynamic point M represents an airplane in the embodiment of the present application. Based on this, in the data of the target route, the position of each position in the spherical coordinate system is represented as (x, y, z), wherein x, y, z satisfy the following formula:

in the formula (1), x represents an abscissa, y represents an ordinate, z represents an ordinate, and R is a spherical radius.

It should be noted that the value range of the spherical coordinate is (-1, 1), that is, the minimum value of the spherical coordinate (x, y, z) is (-1, -1, -1), and the maximum value is (1, 1, 1). In addition, in order to avoid that the data processing is affected by the excessive data amount of the spherical coordinates after each position in the data is converted into a position in the spherical coordinate system, each spherical coordinate can be stored in the rendering device of the navigation path in a matrix multiplication mode so as to be used for subsequent rendering.

And S104, rendering the driving track by the rendering device of the route according to the position in the spherical coordinate system to obtain the rendered track.

Specifically, the airline rendering device may render the driving trajectory by using a webgl (web graphics library) technology. When the driving trajectory is rendered by the WebGL technique, the spherical coordinate system may be referred to as a WebGL coordinate system.

For example, the rendering device of the route may draw coordinates of each position in the spherical coordinate system, add preset route parameters to the drawn coordinates, and render the driving trajectory to obtain a rendered trajectory. The preset route parameters may include, for example, attributes such as color, transparency, and line width.

It can be understood that when the rendering device of the navigation line obtains the rendered track, the rendered track can be displayed, so that the user can see the rendered track, and the visual effect of the user is improved.

In the embodiment of the application, the flight path rendering device determines the driving track of the target flight path according to the acquired data of the target flight path, then converts the coordinates of each position in the data into spherical coordinates, and renders the driving track by adopting a WebGL technology, namely, the coordinates in a spherical coordinate system are drawn, so that the rendered track can be obtained, and therefore the problems that the flight path rendering method in the related technology is complex, the blockage is easy to occur when the data is processed, and the rendering effect is poor can be solved.

Optionally, as shown in fig. 3, before determining the driving track of the target route according to the data, the method for rendering the route further includes:

s101a, the rendering device of the flight path divides the data into a plurality of data groups.

Wherein each data group in the plurality of data groups comprises a starting position, an ending position and an intermediate parameter; the intermediate parameters include at least one of a maximum height, a minimum height, and a unit travel distance; the time corresponding to different data sets is different.

Illustratively, the plurality of data sets includes a first data set, a second data set, and a third data set; the unit durations of the first data group, the second data group and the third data group can be the same or different.

In one example, the unit time lengths of the first data group, the second data group, and the third data group are the same; for example, the time corresponding to the first data group is 10:00-10:05, the time corresponding to the second data group is 10:05-10:10, and the time corresponding to the third data group is 10:10-10: 15. In another example, the unit time lengths of the first data group, the second data group and the third data group are different, for example, the time corresponding to the first data group is 10:00-10:05, the time corresponding to the second data group is 10:05-10:15, and the time corresponding to the third data group is 10:15-10: 30.

It is understood that, in the plurality of data sets, the ending position of the previous data set is the starting position of the next data set. Taking the plurality of data sets including the first data set, the second data set and the third data set as an example, for example, the ending position of the first data set is the starting position of the second data set, and the ending position of the second data set is the starting position of the third data set.

In addition, after dividing the data into a plurality of data groups, for example, the plurality of data groups may satisfy the following format:

[[(x₁,y₁),(x₂,y₂),parmas₁]、[(x₂,y₂)，(x₃,y₃),parmas₂]、…、[(x_n-1,y_n-1)，(x_n,y_n),parmas_n]]

wherein (x)_n-1，y_n-1) Is an initial position, (x)_n，y_n) To the end position, parmas_nRepresenting the intermediate parameter.

It should be noted that the more data groups into which the data are divided, the smoother the travel locus of the determined target route. Based on this, in one possible design, the rendering device of the flight path may also traverse each data set, subdividing each data set into a plurality of sub-data sets, which may, for example, satisfy the following format:

{type:"Feature",geometry:{type:"LineString",coordinates:[(x_o,y_o),(x_e,y_e)]},properties:{}}

wherein (x)_o,y_o) Is the starting position of the sub data group, (x)_e,y_e) The characteristics represent intermediate parameters, and the { } can be at least one of maximum height, minimum height and unit travel distance; in addition, the above format may be referred to as GeoJson data of a standard linesting type.

It should be noted that, for an example of the intermediate parameter included in each data group, reference may be made to the example of the intermediate parameter included in the data in the foregoing embodiment, and details are not described here again.

S101b, the rendering device of the air route determines the sub-track of the target air route according to the data group, and obtains the driving track of the target air route according to the sub-track.

Specifically, each data group comprises a starting position and an ending position, so that the sub-track of the target air route can be determined according to the starting position and the ending position in one data group, and the starting position and the ending position of each data group are determined to obtain the driving track of the target air route.

Exemplarily, taking a target route as a parabola, fig. 4 is a schematic diagram of a driving track of a target route provided by an embodiment of the present application, as shown in fig. 4, (x1, y1) is a start position of a first data set, and (x2, y2) is an end position of the first data set; (x2, y2) is the start position of the second data set, and (x3, y3) is the end position of the second data set; by analogy, the start and end positions of each data set can be marked. In the travel locus shown in fig. 4, the distance between (x1, y1) and (x2, y2) represents sub-loci determined from one data group, and since each sub-locus is continuous, a plurality of sub-loci are linked together to be the travel locus of the target course.

In the embodiment of the application, the rendering device of the air route divides data into a plurality of data groups, and determines the sub-track of the target air route according to the starting position and the ending position in each data group.

Alternatively, as shown in fig. 5, S102 may be replaced by S1021 and S1022. Specifically, S102 includes:

and S1021, the rendering device of the route constructs a functional relation corresponding to the target route according to the data.

For example, taking the target course as a parabola, assuming that the data includes an initial position, an end position and a maximum height, and the coordinates of the initial position are (x1, y1), the coordinates of the end position are (x2, y2) and the coordinates of the maximum height are (x3, y3), the functional relationship satisfies the following equation:

in the formula (2), a, b and c are coefficients of parabolas. It will be appreciated that where the target course is parabolic, the functional relationship is a parabolic equation.

Since (x1, y1), (x2, y2), and (x3, y3) are known, the equation in equation (2) is converted so that the coefficients a, b, c satisfy the following equations:

coefficients a, b and c of the parabola can be calculated according to the formula (3), and then a parabola equation of the target route is constructed according to the coefficients a, b and c.

And S1022, determining the driving track of the target route by the rendering device of the route according to the functional relation.

For example, let the function relationship be y ═ ax²+ bx + c; and calculating a vertex coordinate and a directrix equation according to the functional relation, and determining the driving track of the target air route according to the vertex coordinate and the directrix equation. It is understood that the more the coordinates are calculated, the smoother the parabola, according to a functional relationship, based on which it is also possible to calculate the intersection point of the parabola with the y-axis, with x being equal to 0, and the intersection point of the parabola with the x-axis, with y being equal to 0.

In the embodiment of the application, the rendering device of the route constructs the functional relation corresponding to the target route through the data, and then determines the running track of the target route according to the functional relation, so that the determined running track of the target route is more accurate, and the running track of the target route is smoother.

Optionally, the rendering device of the lane comprises a shader; as shown in fig. 6, S104 may be replaced by S1041-S1044, and specifically, S104 includes:

and S1041, drawing the position in the spherical coordinate system by the rendering device of the flight path according to the shader to obtain a rendered track.

In particular, the shaders include a vertex shader and a fragment shader. The vertex shader is mainly used for processing vertex coordinates, namely processing coordinates of positions in the spherical coordinate system, the vertex shader sends the processed coordinates in the spherical coordinate system to the fragment shader, then the fragment shader paints the drawn coordinates according to preset route parameters to obtain rendered tracks, and finally the rendered tracks are output.

For example, fig. 7 is a schematic diagram of a rendered track provided in an embodiment of the present application, and as shown in fig. 7, the rendered track clearly illustrates a track from an origin to a destination, that is, a route where an aircraft flies from the origin to the destination. For example, rendered traces include: Beijing-Jinan; Taiyuan-Zheng state, etc., are not listed here.

S1042, the rendering device of the flight path modifies the attribute information of the rendered track according to a preset period so that the rendered track has different display modes at different moments.

Wherein the attribute information includes at least one of color, line width, and transparency.

For example, in order to improve the rendering effect, the preset period may be set to 1s, that is, the rendered track is modified every 1 s. It should be noted that only the color, only the line width, or only the transparency may be modified; two or more of the color, the line width and the transparency can be modified, and the modification can be specifically set according to actual needs, and the embodiment of the application is not limited.

In the case where the rendering device of the route modifies the color according to a preset period, for example, the color of the modified trajectory gradually becomes lighter as time increases until the color disappears. In the case where the rendering device of the route modifies the line width according to the preset period, for example, the line width of the modified trajectory gradually narrows with time until it becomes a line, even the line width is zero. In the case where the rendering device of the route modifies the transparency according to a preset period, for example, the transparency of the modified trajectory becomes gradually shallower as time increases until the transparency disappears.

In addition, the preset period may be modified, that is, the speed, length, and the like of the modified track, which change with the time increment, may be modified.

In the embodiment of the application, the rendering device of the route modifies the attribute information of the rendered track, namely modifies the color, the line width and the transparency of the rendered track, so that the rendered track presents a dynamic effect, and the rendering effect is further enhanced.

And S1043, calling the animation model by the rendering device of the flight path, and assigning the position in the spherical coordinate system to the animation model.

Note that the animation model (gltf model) is stored in advance in the rendering device of the flight path. The animated model may be, for example, an airplane model.

Specifically, the rendering device of the airline calls the animation model and uploads the animation model to a graphics processing unit (graphics processor), and after the GPU loads the animation model, the rendering device of the airline assigns a position in the spherical coordinate system to the animation model, thereby ensuring that the animation model is consistent with a rendered track.

And S1044, the rendering device of the flight path adjusts the attitude angle of the animation model according to the data to obtain a rendered dynamic track.

Specifically, the attitude angle includes a heading angle, a pitch angle, and a roll angle. On this basis, at least one of a heading angle, a pitch angle, and a roll angle of the animated model may be adjusted.

Taking the course angle of the animation model as an example, for example, the rendering device of the course calculates the course angle of the animation model at the current moment according to the data of the target course, determines the difference between the course angle of the animation model at the current moment and the target course angle, and then rotates the course angle of the animation model around the z-axis in the spherical coordinate system until the rotated course angle is the same as the target course angle, thereby completing the adjustment of the course angle. It can be understood that the angle of rotation of the heading angle around the z-axis in the spherical coordinate system is the difference between the heading angle of the animated model at the current time and the target heading angle.

It should be noted that the target course angle is the course angle of the animation model at the next moment of the current moment.

In addition, if the calculated heading angle (for example, phi) of the animation model at the current moment is greater than 180 degrees, the compensation angle for the heading angle of the animation model at the current moment needs to be 2 pi-phi. Illustratively, the course angle of the animation model at the current moment is 190 °, and then the compensation angle of the course angle of the animation model at the current moment is 2 pi-190 ° -170 °, that is, during specific implementation, the course angle of the animation model at the current moment is 170 °, and then the difference between the course angle of the animation model at the current moment and the target course angle is determined according to 170 °, and finally the course angle of the animation model is rotated around the z-axis in the spherical coordinate system according to the difference until the rotated course angle is the same as the target course angle, so that the adjustment of the course angle is completed.

Fig. 8 is a schematic diagram of a rendered track provided in an embodiment of the present application, as shown in fig. 8, an animated model (e.g., an airplane model) is included in the rendered track, and it can be seen from fig. 8 that a heading angle of the airplane model coincides with a traveling track of a target route, and transparency of the rendered track decreases with time, that is, transparency of a track close to the airplane model is stronger, and transparency of a track far from the airplane model is weaker.

In the embodiment of the application, the rendering device of the flight path adds the animation model in the rendered track and assigns the position in the spherical coordinate system to the animation model so as to ensure that the animation model is consistent with the rendered track; on the basis, the attitude angle of the animation model is adjusted, so that the animation model can rotate the attitude angle of the animation model according to the rendered track, the rendered track also comprises the animation model, and the rendering effect is further enhanced.

The scheme provided by the embodiment of the application is introduced mainly from the point of interaction between devices. It will be appreciated that each device, in order to carry out the above-described functions, comprises corresponding hardware structures and/or software modules for performing each function.

Whether a function is performed as hardware or computer software drives hardware depends upon the particular application and design constraints imposed on the solution. Skilled artisans may implement the described functionality in varying ways for each particular application, but such implementation decisions should not be interpreted as causing a departure from the scope of the present application.

In the embodiment of the present application, functional modules may be divided according to the above method examples, for example, each functional module may be divided corresponding to each function, or two or more functions may be integrated into one processing module. The integrated module can be realized in a hardware mode, and can also be realized in a software functional module mode. It should be noted that, in the embodiment of the present application, the division of the module is schematic, and is only one logic function division, and there may be another division manner in actual implementation.

For example, the rendering apparatus 200 of the airline may be a server, or may be a chip applied in the server or other combined device, component, etc. having the above-mentioned server function.

Specifically, the obtaining module 201 is configured to obtain data of a target route; the data includes a start location, an end location, and intermediate parameters including at least one of a maximum altitude, a minimum altitude, and a unit distance traveled.
