Obviously, the drawings described below are only some embodiments of the present invention. For ordinary technicians in this field, other drawings can be obtained based on these drawings without creative work.

[0045] Figure 1 A flow chart of a flight trajectory drawing method provided by an embodiment of the present invention. DETAILED DESCRIPTION

[0046] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the present invention.

[0047] A flight trajectory drawing method, such as Figure 1 As shown, the following steps are included:

[0048] Step S100, in response to receiving a flight trajectory drawing request of a target flight; the flight trajectory drawing request includes a user identifier B3 and a departure place identifier B1 and an arrival place identifier B2 corresponding to the target flight;

[0049] The target flight is the historical flight whose flight trajectory needs to be drawn. The user identifier B3 included in the flight trajectory drawing request is the user who sent the flight trajectory drawing request, that is, the user who needs to draw the flight trajectory of the target flight. The departure point identifier B1 corresponding to the target flight is the identifier corresponding to the departure point of the target flight, and the arrival point identifier B2 is the identifier corresponding to the arrival point of the target flight.

[0050] Step S200: If both B1 and B2 exist in the preset flight location identifier list, obtain the departure longitude J1 corresponding to B1 and the arrival longitude J2 corresponding to B2, and execute step S300;

[0051] The flight location identifiers stored in the preset flight location identifier list may be identifiers corresponding to cities with airports in China.

[0052] If the departure place mark and arrival place mark corresponding to the target flight are both in the preset flight location mark list, it means that the departure place and arrival place of the target flight are both domestic cities, and the target flight is a domestic flight. When drawing the flight trajectory of the flight, it is necessary to consider the distance between the departure place and the arrival place to determine the length of the flight trajectory curve, and to draw the flight direction of the flight trajectory. Therefore, the flight direction of the aircraft corresponding to the target flight is determined by comparing the departure longitude and the arrival longitude of the target flight, and then the corresponding trajectory curve is drawn according to the flight direction.

[0053] Step S210: If B1 and / or B2 do not exist in the preset flight location identifier list, obtain the departure longitude J1 corresponding to B1 and the arrival longitude J2 corresponding to B2;

[0054] If the departure place mark and / or arrival place mark corresponding to the target flight does not exist in the preset flight location mark list, it means that the departure place and / or arrival place of the target flight belongs to a foreign city and the target flight is an international flight. Since the flight distance of an international flight is longer than that of a domestic flight and the longitude difference across is larger, it is necessary to set up any place passed by the target flight as an auxiliary point for direction determination, and use the longitude of the departure place and arrival place of the target flight and the established direction determination auxiliary point to accurately determine the flight direction of the aircraft corresponding to the target flight, so that the flight direction of the drawn flight trajectory curve is consistent with the actual flight direction of the target flight.

[0055] Step S220: If J1∈[-180°, 0°] and / or J2∈[-180°, 0°], execute step S230; otherwise, execute step S240;

[0056] In order to facilitate the subsequent comparison of the departure longitude and the arrival longitude of the target flight, the longitude values ​​of -180° to 0° are processed, that is, the longitude of the west longitude is processed so that the longitudes of the east longitude and the west longitude are 0° to 360°.

[0057] Step S230, if J1∈[-180°,0°], set J1=J1+360°; if J2∈[-180°,0°], set J2=J2+360°, and execute step S240;

[0058] Step S240, determining any candidate intermediate place that the target flight passes through as the target intermediate place; the candidate intermediate place is a place with a different longitude from J1 and J2;

[0059] Since the departure and / or arrival place of the target flight is not the place corresponding to the identifier in the flight location identifier list, the distance between the departure place and the arrival place may be very far. In order to match the drawn flight trajectory with the actual flight trajectory, it is necessary to find any place between the departure place and the arrival place and determine it as the target intermediate place, so that the drawn flight trajectory is from the departure place through the target intermediate place to the arrival place.

[0060] Step S250, obtain the longitude J3 of the target middle point; if J3∈[-180°,0°], set J3=J3+360°;

[0061] Step S260: Determine the flight direction of the aircraft corresponding to the target flight according to J1, J2, and J3, and execute step S400.

[0062] Further, in step S260, the flight direction of the aircraft corresponding to the target flight is determined according to J1, J2, and J3, including:

[0063] Step S261: If J2<J3<J1 or J3<J1<J2 or J1<J2<J3, then determine that the aircraft corresponding to the target flight flies westward; if J1<J3<J2 or J3<J2<J1 or J2<J1<J3, then determine that the aircraft corresponding to the target flight flies eastward;

[0064] Step S300, determining the flight direction of the aircraft corresponding to the target flight according to J1 and J2;

[0065] Further, step S300 includes:

[0066] Step S310: If J1∈[-180°, 0°] and / or J2∈[-180°, 0°], execute step S320; otherwise, execute step S330;

[0067] Step S320, if J1∈[-180°,0°], set J1=J1+360°; if J2∈[-180°,0°], set J2=J2+360°, and execute step S330;

[0068] Step S330, determining the direction longitude difference D of the aircraft corresponding to the target flight according to J1 and J2;

[0069] Wherein, step S330 includes:

[0070] Step S331, if J2-J1>180°, determine the direction and longitude difference D=J2-J1-360° of the aircraft corresponding to the target flight; if J2-J1<-180°, determine the direction and longitude difference D=J2-J1+360° of the aircraft corresponding to the target flight; if -180°≤J2-J1≤180°, determine the direction and longitude difference D=J2-J1 of the aircraft corresponding to the target flight.

[0071] Since the longitudes of the departure and arrival points are processed in the range of [0°, 360°], the difference between the longitudes of the arrival point and the departure point may be greater than 180°. In order to determine the flight direction of the target flight, the difference must be subtracted by 360°.

[0072] Step S340: If D>0°, determine that the aircraft corresponding to the target flight is flying eastward; if D<0°, determine that the aircraft corresponding to the target flight is flying westward.

[0073] Step S400, obtaining the current completion number n of the target flight corresponding to B3;

[0074] Step S500: Determine n trajectory auxiliary coordinate points V1, V2, ..., V according to the departure coordinate point Z1 corresponding to B1, the arrival coordinate point Z2 corresponding to B2, n and the flight direction of the aircraft corresponding to the target flight. m ,...,V n ; where m = 1, 2, ..., n; V m is the auxiliary coordinate point of the determined mth trajectory;

[0075] Further, step S500 includes:

[0076] Step S510, obtain the coordinates corresponding to Z1 (Z 11 ,Z 12 ,Z 13 ) and the coordinates corresponding to Z2 (Z 21 ,Z 22 ,Z 23 ), where Z 11 is the horizontal coordinate corresponding to Z1, Z 12 is the ordinate corresponding to Z1, Z 13 is the vertical coordinate corresponding to Z1; Z 21 is the horizontal coordinate corresponding to Z2, Z 22 is the ordinate corresponding to Z2, Z 23 is the vertical coordinate corresponding to Z2;

[0077] The coordinates are the coordinates corresponding to the page or system on which the flight trajectory is drawn, such as the Cesium page, which has the coordinates of each point on the earth.

[0078] Step S520: determine the coordinates (Z 31 ,Z 32 ,Z 33 ), where Z 31 is the horizontal coordinate corresponding to Z3, Z 31 =(Z 11 +Z 21 ) / 2; Z 32 is the ordinate corresponding to Z3, Z 32 =(Z 12 +Z 22 ) / 2; Z 33 is the vertical coordinate corresponding to Z3, Z 33 =(Z 13 +Z 23 ) / 2;

[0079] Step S530: If the aircraft corresponding to the target flight is flying eastward, execute step S540; if the aircraft corresponding to the target flight is flying westward, execute step S550;

[0080] Step S540: Determine n trajectory auxiliary coordinate points V1, V2, ..., V according to Z1, Z2, Z3. m ,...,V n ;

[0081] Among them, V m =(V m1 ,V m2 ,V m3 );V m1 V m The corresponding horizontal axis is V m2 V m The corresponding vertical coordinate is V m3 V m The corresponding vertical coordinate is

[0082] Step S550: Determine n trajectory auxiliary coordinate points V1, V2, ..., V according to Z1, Z2, Z3. m ,...,V n ;

[0083] Among them, V m =(V m1 ,V m2 ,V m3 );V m1 V m The corresponding horizontal axis is V m2 V m The corresponding vertical coordinate is V m3 V m The corresponding vertical coordinate is

[0084] In addition, V m3 It can also be determined by the following steps:

[0085] Step S560: If Then W1 is determined as V m3 ;

[0086] like Then W2 is determined as V m3 ;

[0087] like Then Determined as V m3 ;

[0088] Among them, L1>L2>0; W1>W2; L1 and L2 are preset distance thresholds.

[0089] Step S600: According to Z1, Z2 and V m , draw the flight trajectory of the aircraft corresponding to the mth target flight completed by the user;

[0090] Further, step S600 includes:

[0091] Step S610: According to Z1, Z2 and V m , draw the flight trajectory curve G of the aircraft corresponding to the mth target flight completed by the user m (t) = (1-t) 2 ×Z1+2t(1-t)×V m +t 2 ×Z2; t∈[0,1].
