Referring to fig. 1, according to an aspect of the present application, there is provided a data processing method, including:

and step S100, acquiring a track display request.

And step S200, determining a target flight according to the track display request. The determination of the target flight can be determined according to flight information or user ID information in the trajectory display request.

Step S300, obtaining a trajectory sequence G = { D corresponding to the target flight₁,D₂,...,D_n｝，D_i={A_i ,B_i ,C_i,T_iIn which D is_iRepresents the ith trace point in G, A_iRepresenting the longitude value of the ith track point in G, B_iRepresenting the latitude value, C, of the ith track point in G_iIndicating the height value, T, of the ith trace point in G_iRepresenting the time point of the ith trace point in G, the taking of iThe value ranges from 1 to n. Wherein A is_i ,B_i ,C_iThe positions, T, of the airplanes corresponding to the target flight in the three-dimensional space are determined together_iMay be in the form of a time stamp.

Step S400, sequentially acquiring f (D)_j-1,D_j,D_j+1)，f(D_j-1,D_j,D_j+1) Represents D_j-1，D_j，D_j+1F () is a preset first processing function stored in the configuration file, and j has a value ranging from 2 to n + 1. The first processing function is used for calculating the D_j-1As a starting point, D_jIs a middle point, D_j+1The angle value of the angle formed for the end point, i.e. f (D)_j-1,D_j,D_j+1) To be D_jIs the angle value of the corner point.

Step S500, obtaining a current display scale of a target display window, and determining an angle threshold value alpha according to the current display scale. Under different display scales, the corresponding angle thresholds are different, specifically, α = γ (X × Y/P), where γ is a correction parameter and may be a fixed value set manually, X is the width of the target display window, Y is the height of the target display window, and P is a scale value corresponding to the current display scale.

Step S600, at f (D)_j-1,D_j,D_j+1)<In case of α, D is determined_jReplacement point set D'_j=｛D_j ¹,D_j ²,...D_j ^g ^(j)｝，D_j ^g(j)Is D_jG (j) is a positive integer, and the value of g (j) is given by alpha-f (D)_j-1,D_j,D_j+1) G () is a preset second processing function stored in the configuration file. I.e. at alpha-f (D)_j-1,D_j,D_j+1) In the case where the values of (1) are different, the replacement point set D'_jThe number of replacement points in (a) is different. Specifically, the value of g (j) and alpha-f (D)_j-1,D_j,D_j+1) Negative correlation of (c).

In step S700, D 'is used'_jSubstitution of D in G_jTo obtainTarget track sequence G' such that any f (D) in G_j-1,D_j,D_j+1) Are all greater than or equal to alpha.

And step S800, dynamically displaying the motion trail of the 3D airplane model corresponding to the target flight in the target display window according to G'. The display of the movement trajectory of the 3D airplane model can be done by a 3D engine, which can be based on the position data of the trajectory points in G' (i.e. a_i ,B_i ,C_i) Determining the flight trajectory of the target flight and according to T_iAnd determining the position of the 3D airplane model in the flight trajectory line at each time point, finally displaying the 3D airplane model in a 3D map, and controlling the 3D airplane model to move according to the motion trail so as to realize data processing. And during display, the angle and the direction of the camera are adjusted in the flying process, and the camera is displayed at the first visual angle, namely, the direction of the display visual angle and the 3D airplane model are kept unchanged in the target display window. The apparent distance is shown to remain unchanged from the 3D airplane model.

The data processing method provided by this embodiment can obtain the trajectory sequence G corresponding to the target flight according to f (D)_j-1,D_j,D_j+1) And determining whether the turning angle of the three continuous track points is too small under the current display scale of the target display window (namely f (D)_j-1,D_j,D_j+1)<α). If so, then D is determined_jReplacement point set D'_j=｛D_j ¹,D_j ²,...D_j ^g(j)And (5) to eliminate or reduce the problem that the display effect is influenced due to the undersize turning angle.

splitting G' into a plurality of subsequences according to a splitting rule; each subsequence comprises a plurality of continuous track points; and the splitting rule is to determine adjacent track points of which the speed change and the flight direction change are in the same threshold value section in the track line corresponding to the G' as a subsequence.

When the motion trail of the 3D airplane model is actually displayed, if the distance and the height difference between two adjacent track points are directly obtained according to the longitude and latitude of the two adjacent track points, the motion time is obtained through the time stamp difference, and the speed is obtained through the ratio of the distance to the time. However, because the calculated speed value and direction of each segment are different, the speed value and direction may be suddenly or suddenly changed or stuck during the display, which may not provide good experience for passengers. In this embodiment, G' may be split into a plurality of subsequences according to a splitting rule, each subsequence corresponds to an actual motion state, and it can be known from the foregoing that if the actual motion state is used to control the motion speed of the 3D airplane model in the motion trajectory, the motion speed will be suddenly fast or suddenly slow or will be stuck, so in this embodiment, the display speed of each subsequence is smoothed according to the position, time, and direction corresponding to the first track point and the last track point in each subsequence, so that the processed corresponding target motion states are uniform linear motion, uniform variable linear motion, and uniform steering motion, so as to improve the display effect.

Specifically, in this embodiment, a flight speed calculation unit may be adopted to establish a motion model set for a flight, and in terms of model design, the present embodiment assumes that an aircraft has three states: uniform linear motion, uniform acceleration linear motion and uniform rotation. According to the analysis of adjacent multiple segments of data, a motion model of a flight is identified, a normalized difference value is calculated in each step, a threshold value is set to distinguish noise and maneuvering change, residual errors along the speed direction and the vertical speed direction need to be calculated, and then whether the aircraft enters an accelerating or turning state is judged. Finally, according to the probability that the plane is in a certain state in each stage, the simulated track speed and the preset sensory coefficient are obtained to obtain the playback time between two adjacent track points of the simulated track, so that the change of the uniform speed state is more stable, and the acceleration and the turning can be timely and smooth and close to the reality.

Meanwhile, flight data can be obtained through the flight calculation unit, and the flight data comprises at least one of the following: and the state information in the flight process, such as longitude and latitude data, target longitude and latitude data, a course angle, a current rudder position, a target rudder position, flight height, steering data, a shaking coefficient, flight time information and the like, wherein the rudder position comprises a direction, a lifting angle and an airplane inclination angle so as to expand the display data.

And finally, finishing the flight data assignment in a 3D engine (namely G' after each subsequence is adjusted), finishing the specified 3D animation effect in corresponding time, and taking the user to enter a 3D stereoscopic world to transfer the flight from the plane map to the air. The space sense and the expressive force are better, and brand new visual experience is brought to the user.

acquiring original track data from a plurality of data sources;

Obtaining track data (original track data) from an ADSB data source, extracting flight numbers, timestamps and three-dimensional coordinate points, and sorting the flight numbers, the timestamps and the three-dimensional coordinate points into a plurality of track sequences which are corresponding to the flight numbers and are composed of four-dimensional vectors. The four-dimensional vector refers to longitude, latitude, altitude, and time (i.e., G'). The data formats of G '' and G are the same.

However, because the ADSB data sources are not unique, formats of track data uploaded by each data source may be different, and data repetition and data overload in the same time period may exist among a plurality of data sources, so in this embodiment, data format processing, data denoising, and data thinning are sequentially performed on the original track data to obtain processed track data, so that the data in the processed track data have the same format and do not have the data repetition and data overload in the same time period.

Meanwhile, aiming at multi-source track data from air traffic control, department of aviation and the like, a unified and standardized track data storage model and a unified and standardized track data storage mode are established according to a specified data format, the preprocessed track data are subjected to standardized storage, and flights indexed by taking flight numbers and timestamps as main keys are formed, so that quick and flexible query is facilitated.

acquiring an original track sequence G '' corresponding to the target flight;

and performing Kalman filtering on the G '' to obtain a track sequence G.

Due to the data exception in the case of the track data part, the situations of missing, interruption and instability exist, and the track points in the original track sequence G ″ will be partially abnormal points. Due to the existence of the abnormal points, the drawn flight track has shapes of sawteeth, burrs and the like, and poor experience is brought to a user. In this embodiment, a smooth curve (i.e., the trajectory sequence G) is obtained by performing denoising, thinning and kalman filtering on the original trajectory sequence G ″.

the first acquisition unit is used for acquiring a track display request;

the fourth acquisition unit is used for acquiring the current display scale of the target display window and determining an angle threshold alpha according to the current display scale;
