[0002] Trajectory playback plays an important role in aspects such as data traceability, data rectification, and analysis and decision-making. In the prior art, trajectory playback generally adopts a static marking method. Among them, the static marking method marks each collected point in sequence and connects the points in sequence to achieve the effect of viewing the trajectory.

[0003] However, although the static marking method can display the trajectory points and trajectory routes of an object, in the case of dense collection, the points are dense, making it difficult to view the moving trajectory of the object, and it is also impossible to feedback the time the object stays at the points and the change in the moving speed, that is, only static trajectory playback can be achieved in the prior art. Summary of the Invention

[0007] When the travel data of the current segmented trajectory is played out, play the travel data of the next segmented trajectory until the target trajectory playback ends;

[0008] Wherein, each segmented trajectory is obtained by splitting a number of positioning points included in the target trajectory, the playback speed of each segmented trajectory is determined based on any two positioning points in this segmented trajectory, and the end point of the current segmented trajectory is the starting point of the next segmented trajectory.

[0009] In a second aspect, an embodiment of this application further provides a trajectory playback apparatus, which includes:

[0010] A playback module, configured to, in response to a playback operation for a target trajectory, take the first segmented trajectory of the target trajectory as the current segmented trajectory, and play the travel data of this segmented trajectory starting from the starting point of the current segmented trajectory; when the travel data of the current segmented trajectory is played out, play the travel data of the next segmented trajectory until the target trajectory playback ends;

[0011] Among them, each segmented trajectory is obtained by dividing a number of positioning points included in the target trajectory. The playback speed of each segmented trajectory is determined based on any two positioning points in the segmented trajectory, and the end point of the current segmented trajectory is the start point of the next segmented trajectory.

[0012] In a third aspect, the present application further provides an electronic device, which includes a memory and a processor.

[0015] The beneficial effects brought by the technical solution provided by the present application are as follows:

[0016] The trajectory playback method provided by the embodiment of the present application. Specifically, when responding to a playback operation for a target trajectory, the first segmented trajectory of the target trajectory is used as the current segmented trajectory, and the travel data of this segmented trajectory is played starting from the start point of the current segmented trajectory; when the travel data of the current segmented trajectory is played out, the start point of the next segmented trajectory can be determined based on the end point of the current segmented trajectory, and then the travel data of the next segmented trajectory is played. At this time, the next segmented trajectory replaces the current segmented trajectory until the target trajectory playback ends; among them, since each segmented trajectory is obtained by dividing a number of positioning points included in the target trajectory, that is, a target trajectory can be divided into several segmented trajectories based on positioning points, and each segmented trajectory has its own corresponding start point and end point. On this basis, the playback speed of each segmented trajectory is determined based on any two positioning points in the segmented trajectory; that is, the playback speeds of each segmented trajectory are different. The implementation of the present application realizes dynamic trajectory playback by dynamically configuring the playback speed of each segmented trajectory. Dynamic trajectory playback can reflect the time the object stays at a point, the speed change during the travel process, etc., and improve the experience of trajectory playback.

[0031] This application is directed to the problem that in the existing solutions, during the application of the trajectory playback function, generally only each collected point can be marked in sequence and connected in sequence to achieve the effect of viewing the trajectory. In the case of dense collection, the points are dense, making it difficult to view the travel trajectory of the object, and it is also impossible to feedback the time the object stays at the points and the change in the travel speed. A trajectory playback method, device, equipment, storage medium and program product are proposed. Based on the implementation of this solution, dynamic trajectory playback can be achieved.

[0032] The solution of the embodiment of this application relates to an intelligent transportation system and can be applied to scenarios such as outdoor navigation (such as driving / cycling / walking navigation), indoor navigation, food delivery, online car-hailing, etc. Based on the solution of the embodiment of this application, dynamic trajectory playback can be achieved. For example, in the food delivery scenario, through the trajectory playback function, the stay time of the delivery person at each point in the travel trajectory of food delivery and the change in speed during the travel process can be understood.

[0033] The following will specifically describe the technical solution of this application and how the technical solution of this application solves the above technical problems with specific embodiments. These specific embodiments can be combined with each other, and the same or similar concepts or processes may not be repeated in some embodiments. The embodiments of this application will be described below with reference to the accompanying drawings.

[0034] Figure 1 The flowchart of a trajectory playback method provided by the embodiment of this application is shown. This method can be executed by any electronic device, such as a terminal. The terminal can be a smart phone, a tablet computer, a laptop computer, a desktop computer, a smart speaker, a smart watch, a vehicle-mounted device, a detector, etc., but is not limited thereto.

[0035] Such as Figure 2As shown in the figure, the implementation of the embodiments of the present application may involve a terminal 20, a server 10, a network 30, and a database 40. Among them, the terminal 20 and the server 10 may be connected through the network 30. When the terminal 20 requests data from the server 10 (such as obtaining the travel data of the target trajectory), the server 10 may call the data stored in the database 40 and feedback it to the terminal 20.

[0036] The embodiments of the present application provide a possible implementation manner. As Figure 1 shown in the figure, a flowchart of a trajectory playback method is provided. This solution can be executed by any electronic device. Optionally, it can be executed on the server side or the terminal device. As Figure 1 shown in the figure, the method may include the following steps S101-S102:

[0037] Step S101: In response to a playback operation for the target trajectory, take the first segment trajectory of the target trajectory as the current segment trajectory, and start playing the travel data of this segment trajectory from the starting point of the current segment trajectory.

[0038] Specifically, the target trajectory may be a travel trajectory determined based on a complete trajectory of the end of travel. For example, in the food delivery scenario, when the food delivery task is completed, the complete trajectory corresponding to the food delivery can be determined. As Figure 3 shown in the figure, assuming that A is the rider's pick-up location (i.e., the location of the merchant, the starting point of the complete trajectory), and B is the goods delivery location (i.e., the location where the goods are received, the end point of the complete trajectory), then Figure 3 the path from point A to point B shown by the dotted line in the figure is the complete trajectory corresponding to the food delivery. The target trajectory may be the whole of this complete trajectory or a part of this complete trajectory. Among them, the complete trajectory may also be referred to as the original trajectory or the current trajectory in the embodiments of the present application.

[0039] Specifically, the playback operation is an operation in which an object using the client triggers a corresponding control to control the playback of the target trajectory. Optionally, after the target trajectory is determined, a playback control for controlling the playback may be displayed on the trajectory playback interface. When an object using the client triggers this playback control, the client responds to the playback operation.

[0040] Among them, each segment trajectory is obtained by splitting a number of positioning points included in the target trajectory, and the playback speed of each segment trajectory is determined based on any two positioning points in this segment trajectory.

[0041] Specifically, after determining the target trajectory, several positioning points included in the target trajectory (which can be points determined based on longitude and latitude) can be used to segment the target trajectory, obtaining several segmented trajectories; that is, the positioning points can be used as segmentation points to segment the target trajectory. Among them, each segmented trajectory has its corresponding start point and end point. Among them, the playback speed of each segmented trajectory can be determined based on the start point and end point of the segmented trajectory, such as determined based on the movement speed corresponding to the start point and end point; it can also be determined by selecting the movement speed corresponding to any two positioning points in the segmented trajectory.

[0042] For example: Example 1, after segmenting the target trajectory, three segmented trajectories are obtained (when sorted according to the traveling direction, corresponding to the first segmented trajectory, the second segmented trajectory, and the third segmented trajectory). When responding to the playback operation, the first segmented trajectory of the target trajectory is used as the current segmented trajectory, and the traveling data of this segmented trajectory is played starting from the start point of the current segmented trajectory; among them, the traveling data can include the traveling path.

[0043] Step S102: When the traveling data of the current segmented trajectory is played out, play the traveling data of the next segmented trajectory until the playback of the target trajectory ends.

[0044] Specifically, since the segmented trajectory is obtained by segmenting the target trajectory based on the positioning points in the target trajectory, the end point of the previous segmented trajectory is equivalent to the start point of the next segmented trajectory, that is, the end point of the current segmented trajectory is the start point of the next segmented trajectory.

[0045] Taking the above Example 1 as an example: When the traveling data of the first segmented trajectory is played out, the next segmented trajectory can be determined based on the end point of the current segmented trajectory, and then the traveling data of the next segmented trajectory (the second segmented trajectory) is played. At this time, the second segmented trajectory is the current segmented trajectory; when the traveling data of the second segmented trajectory is played out, the next segmented trajectory can be determined based on the end point of the current segmented trajectory, and then the traveling data of the next segmented trajectory (the third segmented trajectory) is played. At this time, the third segmented trajectory is the current segmented trajectory; when the traveling data of the third segmented trajectory is played out, that is, the playback of the target trajectory ends.

[0046] Next, the triggering of the playback operation and the specific process of responding to the playback operation in the embodiments of the present application will be described.

[0047] In a feasible embodiment, in step S101, in response to the playback operation on the target trajectory, taking the first segmented trajectory of the target trajectory as the current segmented trajectory and playing the traveling data of this segmented trajectory starting from the start point of the current segmented trajectory includes one of the following steps A1 - A2:

[0048] Step A1: In response to a first playback operation triggered by using the original trajectory as the target trajectory, set the original trajectory as the target trajectory, and set the first segmented trajectory of the target trajectory as the current segmented trajectory, and play the travel data of this segmented trajectory starting from the starting point of the current segmented trajectory.

[0049] Specifically, as Figure 3 shown, when there is an original trajectory (the path between the starting point A and the ending point B, represented by a dotted line), the application interface displays a control for triggering the first playback operation, such as the "Full Playback" operation control shown in a dotted box. An object using the client can control using the original trajectory as the target trajectory for trajectory playback by triggering this control. Specifically, as Figure 4 shown, the path between the starting point A and the ending point B changes to be represented by a solid line (indicating that the original trajectory is used as the target trajectory), and then the travel data is played starting from the starting point of the first segmented trajectory of the target trajectory (corresponding to point A).

[0050] Step A2: In response to an intercepting operation for intercepting a target trajectory from the original trajectory, intercept the original trajectory with a target starting point and a target ending point corresponding to this intercepting operation to obtain the target trajectory; in response to a second playback operation triggered for the target trajectory, set the first segmented trajectory of the target trajectory as the current segmented trajectory, and play the travel data of this segmented trajectory starting from the starting point of the current segmented trajectory.

[0051] Specifically, the application interface also displays a control for triggering the intercepting of a target trajectory from the original trajectory. An object using the client can control intercepting a target trajectory from the original trajectory for trajectory playback by triggering this control. Among them, the intercepting operation carries information about the target starting point and the target ending point (such as longitude and latitude coordinate information). Specifically, the application interface also displays a control for triggering the second playback operation. An object using the client can control using the intercepted target trajectory for trajectory playback by triggering this control. Specifically, as Figure 7 shown, the path between point A and point B is represented by a dotted line for the original trajectory, and the path between point C and point D is represented by a thin solid line for the target trajectory, and then the travel data is played starting from the starting point of the first segmented trajectory of the target trajectory (corresponding to point C).

[0052] In a feasible embodiment, in step A2, in response to an intercepting operation for intercepting a target trajectory from the original trajectory, intercepting the original trajectory with a target starting point and a target ending point corresponding to this intercepting operation to obtain the target trajectory includes one of the following steps A21 - step A22:

[0053] Step A21: In response to a selection operation of selecting a target trajectory from an original trajectory, a selection window is displayed. The selection window includes a start point input box, an end point input box, and a confirmation control for triggering a clipping operation, and the number of positioning points included in the original trajectory is displayed in the selection window; the first positioning point value entered in the start point input box and the second positioning point value entered in the end point input box are received; in response to a triggering operation on the confirmation control, the original trajectory is clipped with the positioning point corresponding to the first positioning point value as the target start point and the positioning point corresponding to the second positioning point value as the target end point to obtain the target trajectory.

[0054] Specifically, as Figure 3 shown, when there is an original trajectory (the path between the start point A and the end point B, represented by a dotted line), a control for triggering a selection operation is displayed on the application interface, such as the "Select Playback" operation control displayed in a dotted box. An object using the client can enter the selection stage of the target trajectory by triggering this control. As Figure 5 shown, in response to the selection operation, a selection window (such as the small window of "Select Playback Start and End Points" shown in the upper right corner of the interface) can be displayed on the application interface. The following contents are displayed in the selection window:

[0055] Start point input box: An object using the client can enter a number in this input box, or can select the number of the positioning point from the corresponding drop-down options by triggering the input box.

[0056] End point input box: An object using the client can enter a number in this input box, or can select the number of the positioning point from the corresponding drop-down options by triggering the input box.

[0057] Confirmation control for triggering the clipping operation: Such as Figure 5 the "Confirm" control shown in a dotted box in the small window.

[0058] The number of positioning points included in the original trajectory, such as Figure 5 shown as "The current trajectory has a total of 20 points".

[0059] Optionally, the selection window may further include a trigger control for restoring the original scale. Since it may be necessary to reduce the display scale of the map to completely display the original trajectory in the visible area of the application interface, however, after reducing the display scale, it is difficult for an object using the client to determine the corresponding relationship between the selected target trajectory and the original trajectory. Therefore, an object using the client can enlarge the display scale of the map by triggering the trigger control for restoring the original scale. Among them, the original scale can be the default scale or a scale preset by an object using the client.

[0060] Specifically, when an object using the client triggers the determination control, the positioning point corresponding to the first positioning point value entered in the start input box is determined as the target start point, and the positioning point corresponding to the second positioning point value entered in the end input box is determined as the target end point. Among them, as Figure 5 shown, when the original trajectory includes 20 positioning points, each positioning point has a corresponding sorting value according to the traveling direction. When the first positioning point value entered in the start input box is 1, the 1st positioning point in the original trajectory is used as the target start point of the target trajectory; when the second positioning point value entered in the end input box is 18, the 18th positioning point in the original trajectory is used as the target end point of the target trajectory; then the trajectory between the 1st positioning point and the 18th positioning point in the original trajectory is intercepted as the target trajectory.

[0061] Step A22: In response to the selection operation of selecting the target trajectory from the original trajectory, display several positioning points included in the original trajectory; in response to the selection operation of the first positioning point and the second positioning point in the original trajectory, determine the target start point and the target end point based on the traveling direction, the first positioning point, and the second positioning point of the original trajectory; in response to the interception operation of intercepting the target trajectory from the original trajectory, intercept the original trajectory with the target start point and the target end point to obtain the target trajectory.

[0062] Specifically, as Figure 3 shown, when there is an original trajectory (the path between the start point A and the end point B, represented by a dotted line), the application interface displays a control for triggering the selection operation, such as the "Select Playback" operation control displayed in a dotted box. An object using the client can enter the selection stage of the target trajectory by triggering this control. As Figure 6 shown, in response to the selection operation, the positioning points included in the original trajectory are displayed on the original trajectory of the application interface. The positioning points include point A (start point) and point B (end point) represented by circles, and six points represented by diamonds.

[0063] Specifically, after the positioning points are displayed in the original trajectory, an object using the client can select two of these positioning points according to requirements. As Figure 6 shown, an object using the client can select point D as the first positioning point and point C as the second positioning point. Since there is no limitation on the selected start point and end point when selecting the positioning points, the traveling direction of the original trajectory (from point A to point B) can be combined to determine that point C is the target start point and point D is the target end point.

[0064] Specifically, as Figure 6 shown, the target trajectory is intercepted from the original trajectory with the selected target start point and target end point. The start point of this target trajectory is point C and the end point is point D.

[0065] The following describes the specific process of dividing the target trajectory into several segmented trajectories in the embodiments of the present application.

[0066] In a feasible embodiment, dividing the several positioning points included in the target trajectory to obtain each segmented trajectory includes the following steps B1 - B3:

[0067] Step B1: Obtain the travel data corresponding to the target trajectory, where the travel data includes several positioning points and the moving speed corresponding to each positioning point.

[0068] Specifically, the travel data may be data generated when an object is traveling in real time. For example, in the food delivery scenario, it is the data generated when a rider picks up goods from a merchant and travels along the navigation route to the order delivery location. Optionally, the travel data may include several positioning points included in the trajectory and the moving speed of the object passing through each positioning point.

[0069] Step B2: Divide the target trajectory based on a preset segmentation method to obtain several segmented trajectories; each segmented trajectory has a corresponding starting point and ending point; wherein, the preset segmentation method includes at least one of the method of segmenting one by one based on positioning points, the method of segmenting based on landmarks, and the method of segmenting based on moving speed.

[0070] Specifically, the preset segmentation method includes the following possible methods:

[0071] (1) The method of segmenting one by one based on positioning points: As Figure 6 shown, the target trajectory includes four positioning points (covering the starting point and the ending point). When it is from positioning point C - positioning point 1 - positioning point 2 - positioning point D, it can be segmented into three segmented trajectories. The first segmented trajectory is formed by positioning point C and positioning point 1, the second segmented trajectory is formed by positioning point 1 and positioning point 2, and the third segmented trajectory is formed by positioning point 2 and positioning point D.

[0072] (2) The method of segmenting based on landmarks: During the process of traveling along the path corresponding to the target trajectory, various landmarks may be passed, such as tourist attractions, shopping centers, office buildings, etc. Optionally, the setting of landmarks can be based on the application scenario. For example, in the food delivery scenario, landmarks can be set as office buildings, residential areas, etc. On this basis, when the target trajectory includes 5 positioning points (starting point - positioning point 1 - positioning point 2 - positioning point 3 - ending point), and positioning point 1 and the ending point involve landmark areas, the target trajectory can be segmented into two segmented trajectories. The first segmented trajectory is formed by the starting point and positioning point 1, and the second segmented trajectory is formed by positioning point 1 and the ending point.

[0073] (3) In the way of dividing by moving speed: The moving speed difference between positioning points can be preset as V1. When the moving speed difference between a latter positioning point and a former positioning point is greater than or equal to V1, the latter positioning point is regarded as a dividing point to divide the target trajectory.

[0074] Step B3: For each segmented trajectory, determine the playing speed of the segmented trajectory based on the average moving speed of any two positioning points in the segmented trajectory.

[0075] Specifically, the playing speed of each segmented trajectory can be expressed by the following formula (1):

[0076] Vi = (V1 + V2) / 2

[0077] ...... Formula (1)

[0078] Wherein, in formula (1), Vi is the playing speed of the i-th segmented trajectory, V1 is the moving speed of a positioning point in the i-th segmented trajectory, and V2 is the moving speed of another positioning point in the i-th segmented trajectory. Assuming that the target trajectory is segmented in the above way of segmenting by positioning points one by one, then the i-th segmented trajectory only includes two positioning points, the starting point i and the ending point i + 1. At this time, V1 is the moving speed corresponding to the starting point i, and V2 is the moving speed corresponding to the ending point i + 1.

[0079] Optionally, two positioning points with the largest moving speed difference in the segmented trajectory can be selected for calculating the playing speed, or the starting point and the ending point in the segmented trajectory can be selected for calculating the playing speed.

[0080] Optionally, the above steps B1 - B3 can be executed by the terminal. For example, after the target trajectory is determined, the corresponding steps are executed. Optionally, the above steps B1 - B3 can also be executed by the server. After the terminal determines the target trajectory, it transmits the data related to the target trajectory to the server, and the server performs the segmentation process of the target trajectory and feeds back the results of each operation step to the terminal.

[0081] Next, the specific process of the front-end layout for segmenting the target trajectory into several segmented trajectories in the embodiments of the present application will be described.

[0082] In a feasible embodiment, when dividing the several positioning points included in the target trajectory to obtain each segmented trajectory, the following steps B4 - B5 are further included:

[0083] Step B4: For each segmented trajectory, determine the playing time of the segmented trajectory based on the distance between the starting point and the ending point of the segmented trajectory and the playing speed.

[0084] Specifically, the track length of each segmented track is equal to the distance between the starting point and the ending point of the segmented track. When determining the playing time of the segmented track, it can be determined based on the track length and playing speed of the segmented track. For example, if the track length of the first segmented track is S1 and the playing speed is V1, then its playing time T1 = S1 / V1.

[0085] Step B5: Determine the total playing time of the target track as the sum of the playing times of each segmented track.

[0086] Specifically, assuming that the target track includes N segmented tracks, the total playing time of the target track can be expressed by the following formula (2):

[0087] t = s1 / v1 + s2 / v2 + … + sn / vn

[0088] ......Formula (2)

[0089] Where, t is the total playing time of the target track, s1 is the track length of the first segmented track, v1 is the playing speed of the first segmented track, and so on.

[0090] Optionally, the above steps B4 - B5 can be executed by the terminal. For example, after determining the playing speeds of each segmented track, the corresponding steps are executed. Optionally, the above steps B4 - B5 can also be executed by the server. After the terminal determines the target track, it transmits the data related to the target track to the server. After the server performs the segmentation process on the target track, it determines the total playing time of the target track and feeds back the results of each operation step to the terminal.

[0091] Through the operation and processing of the above steps B1 - B5, the travel data S - new of the target track can be obtained: [{path: [latitude and longitude of the starting point of s1, latitude and longitude of the ending point of s1], speed: v1}…].

[0092] Playing the travel data of the segmented track starting from the starting point of the current segmented track in step S101 includes the following steps C1:

[0093] Step C1: Play the travel data of the segmented track starting from the starting point of the current segmented track on the track playback interface, and display a playback bar based on the total playing time; the playback bar is used to identify the playback progress of the target track.

[0094] Specifically, as Figure 4 、 Figure 7 and Figure 8 shown, a playback bar can be displayed at the bottom of the track playback interface, and the total playing time and the time corresponding to the current playback progress are displayed on the right side of the playback bar. Among them, as Figure 4As shown, when the original trajectory is used as the target trajectory, the total playback time is 26 minutes. The current playback reaches 13 minutes, and the black part in the playback bar accounts for half of the whole, which is used to represent that the current playback reaches half of the path of the original trajectory.

[0095] Optionally, Figure 5 and Figure 6 a playback bar can also be arranged.

[0096] In a feasible embodiment, the playback bar includes a switching control for controlling pause playback or resume playback; specifically, as Figure 4 , Figure 7 and Figure 8 shown, a switching control is arranged on the left side of the playback bar, and the same switching control can control pause playback or resume playback.

[0097] Specifically, the trajectory playback method provided by the embodiment of the present application further includes the following steps C2-step C3:

[0098] Step C2: During the playback of the travel data, in response to a first trigger operation on the switching control, pause the playback of the travel data.

[0099] Step C3: During the pause of the playback of the travel data, in response to a second trigger operation on the switching control, resume the playback of the travel data.

[0100] Specifically, during the playback of the travel data, when an object of the client triggers the switching control, that is, control to pause the playback of the travel data; during the pause of the playback of the travel data, when an object of the client triggers the switching space, that is, control to resume the playback of the travel data from the paused position.

[0101] Next, the specific content of the background execution logic of the trajectory playback method provided by the embodiment of the present application will be described.

[0102] Specifically, the following data is defined during the background execution:

[0103] 1. The movement status moveStatus of the current moving point, whose initial value is init; the movement status includes: initial init; start start; in progress moving; end end;

[0104] 2. The current playback of which segment of the trajectory moveIndex, the initial value is 0

[0105] 3. The passed path passedPathref, the initial value is [].

[0106] In a feasible embodiment, when playing the travel data of the current segmented trajectory starting from the starting point in step S101, it includes the following steps D1 - step D2:

[0107] Step D1: When starting to play the travel data of the current segmented trajectory, set the movement state of the moving point to start.

[0108] Step D2: When playing the travel data of the current segmented trajectory, trigger the in - progress event of the moving point.

[0109] Specifically, during the playback of the target trajectory, a moving point identifier is also used to indicate the progress in the target trajectory. For example, Figure 4 As shown, a five - pointed star is used to represent the moving point.

[0110] Specifically, the execution logic in the background includes:

[0111] Point 1: When triggering the start of playback, the travel data of the first segmented trajectory can be played by calling the uniform - speed trajectory playback api - moveAlone. Among them, the uniform - speed trajectory playback api - moveAlone plays the first segmented trajectory at a uniform speed using the overall playback speed of the original trajectory.

[0112] Point 2: When the moving point moves, trigger the in - progress moving event of the moving point. When the moving point finishes moving, trigger the end - of - movement moveend event. When the moving point starts to move, the movement state moveStatu can be set to start. During the movement of the moving point, in the in - progress moving event of the moving point, continuously update the passed path passedPathref of the movement and assign it to the polylinePath of the movement trajectory.

[0113] In a feasible embodiment, based on the implementation of the above steps D1 - D2, when the travel data of the current segmented trajectory finishes playing in step S102, play the travel data of the next segmented trajectory until the playback of the target trajectory ends, including the following steps D3 - step D5:

[0114] Step D3: When the travel data of the current segmented trajectory finishes playing, trigger the end - of - movement event of the moving point and set the movement state of the moving point to end.

[0115] Step D4: In the end - of - movement event, increment the label identifying the current segmented trajectory by 1, play the travel data of the next segmented trajectory, trigger the in - progress event of the moving point, and set the movement state of the moving point to start until the playback of the last segmented trajectory of the target trajectory ends.

[0116] Step D5: When the playback of the target trajectory ends, set the moving state of the moving point to the initial state, and set the label for identifying the segmented trajectory to a preset value.

[0117] Among them, the preset value can be 0.

[0118] Specifically, based on the above points 1 and 2, the execution logic of the background further includes the following points 3 - 5:

[0119] Point 3: After the current segmented trajectory is played at a constant speed (the corresponding travel data is played at the playback speed of this segmented trajectory) and ends, set the moving state moveStatu of the moving point to end. In the moveend event of the moving point's movement end, increment the label value moveIndex of the recorded segmented trajectory by 1. After setting the travel data of the next segmented trajectory to be played back, the movement effect of the moving point on the next segmented trajectory can be achieved by calling the moving point api - moveTo.

[0120] Point 4: Repeat the process of points 2 - 3 until the label moveIndex of the recorded segmented trajectory is the last segment of the segmentation. After the movement of the moving point ends, set the moving state moveStatue to init and the label moveIndex to 0 to restore the initial state.

[0121] Point 5: The playback control can call the trajectory playback tool through the interface api. Among them, the pause control corresponding to the switching control can be: marker instance.pauseMove(); the resume control corresponding to the switching space can be: marker instance.resumeMove().

[0122] Next, the specific processing process regarding the visualization part in the embodiments of the present application will be described.

[0123] In a feasible embodiment, during the playback of the target trajectory, a first element is used on the trajectory playback interface to identify the travel position of the moving point in the target trajectory.

[0124] Among them, the first element can be set accordingly according to the application scenario. For example, in the food delivery scenario, the first element can be the icon of an electric scooter. As Figure 4 、 Figure 7 and Figure 8 shown, the first element can be a five - pointed star icon. By displaying the five - pointed star icon in the target trajectory, it represents the travel position of the moving point during the trajectory playback.

[0125] In a feasible embodiment, on the trajectory playback interface, the starting point of the target trajectory is identified by a second element, and the ending point of the target trajectory is identified by a third element.

[0126] Among them, to better distinguish the target trajectory from the original trajectory, the starting point of the target trajectory can be identified by a second element and the ending point of the target trajectory can be identified by a third element. For example, Figure 7 As shown, the starting point of the target trajectory is C and the ending point is D. Then, a hollow diamond can be used to identify the target starting point and the target ending point respectively.

[0127] Optionally, the second element and the third element can be the same or different; among them, the second element can adopt a text icon of "start", and the third element can adopt a text icon of "end".

[0128] In a feasible embodiment, on the trajectory playback interface, the original trajectory is displayed by a first identification information, the target trajectory is displayed by a second identification information, and the segmented trajectory of the played travel data is displayed by a third identification information.

[0129] Specifically, the identification information can be information such as line type, line thickness, color, etc.; for example: Figure 7 As shown, the first identification information is a dotted line, the second identification information is a thin solid line, and the third identification information is a thick solid line. Optionally, the first identification information can be color A, the second identification information can be color B, and the third identification information can be color C.

[0130] Among them, the third identification information is only displayed in the path after the moving point passes by. For example, Figure 4 and Figure 7 As shown, in the target trajectory, the third identification information is only displayed in the path traveled by the moving point.

[0131] In a feasible embodiment, the trajectory playback method provided by the embodiments of the present application can be applied to analyze data or make travel decisions in some scenarios. For example, Figure 8 As shown, assuming it is a food delivery scenario, it can be determined the relationship between the deliveryman's travel route in the currently played video and the area shown by the dotted line box in the figure to determine whether the deliveryman enters the area shown by the dotted line box. If the deliveryman stays at the current positioning point for more than a preset duration, it can be determined that the deliveryman enters the area shown by the dotted line box.

[0132] An embodiment of the present application provides an intuitive dynamic trajectory playback solution that can feedback the travel trajectory and the change in travel speed of a traveling object. The trajectory playback can be paused or continued according to the needs of the object using the client, and the start and end points of the playback can also be selected (intercept the target trajectory) to focus on the key trajectory that the user wants to view in the trajectory, which can intuitively assist in tracing the trajectory of the traveling object, performing road segment data analysis, optimizing algorithm data, discovering problems, and mining more solutions that are beneficial to improving the travel experience (for example, in the case of food delivery scenarios, more solutions that are beneficial to improving the delivery of orders by delivery personnel can be mined).

[0133] Based on the same principle as the above method embodiment, an embodiment of the present application also provides a trajectory playback device, as shown in Figure 9 shown in, the trajectory playback device 100 may include a playback module 101.

The processor executes the above computer program to implement the steps of the trajectory playback method. Compared with the related art, it can be realized that: in response to a playback operation for a target trajectory, the first segmented trajectory of the target trajectory is used as the current segmented trajectory, and the traveling data of this segmented trajectory is played starting from the starting point of the current segmented trajectory; when the playback of the traveling data of the current segmented trajectory ends, the starting point of the next segmented trajectory can be determined based on the ending point of the current segmented trajectory, and then the traveling data of the next segmented trajectory is played. At this time, the next segmented trajectory replaces the current segmented trajectory until the playback of the target trajectory ends; wherein, since each segmented trajectory is obtained by dividing a plurality of positioning points included in the target trajectory, that is, a target trajectory can be divided into several segmented trajectories based on the positioning points, and each segmented trajectory has its own corresponding starting point and ending point. On this basis, the playback speed of each segmented trajectory is determined based on any two positioning points in this segmented trajectory; that is, the playback speeds of each segmented trajectory are different. The implementation of the present application realizes dynamic trajectory playback by dynamically configuring the playback speed of each segmented trajectory. The dynamic trajectory playback can reflect the time the object stays at the point and the speed change during the traveling process, etc., and improves the experience of trajectory playback.
