Detailed Description
In order to make the objects, technical solutions and advantages of the present invention more apparent, the present invention is described in further detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.
Fig. 1 shows a first embodiment of the method for synchronizing the vehicle track playback and the play progress bar of the map system according to the invention. In this embodiment, as shown in fig. 1, the method for synchronizing the vehicle track playback and the play progress bar in the map system includes:
and step S1, acquiring a track point sequence of a preset time period in the historical travel of the vehicle and longitude and latitude sequence data corresponding to the track point sequence.
In the embodiment of the invention, the track point sequence is a set of all track points which are sequenced according to time in the historical driving route of the vehicle within the preset time period of the vehicle. The longitude and latitude sequence data is a set of longitude and latitude data corresponding to each track point in a driving route of the vehicle within a preset time period, for example, the longitude and latitude data of one track point in a historical travel of the vehicle can be described as ' north latitude N22 degrees 32 ' 7.15 ' east longitude E113 degrees 55 ' 54.26 '. It should be noted that the initial longitude and latitude data may be acquired by a vehicle-mounted GPS device. After the initial longitude and latitude data are obtained, corresponding longitude and latitude coordinate conversion is needed according to different map systems. Taking a hundred-degree map system as an example, the initial longitude and latitude data are converted into longitude and latitude data under a mars coordinate system, and then secondary encryption is carried out on the basis of the mars coordinate system, so that the longitude and latitude data of the hundred-degree coordinate system are obtained.
And step S2, constructing a vehicle historical track route on the map page according to the longitude and latitude sequence data, and generating a vehicle track playback route covering the historical track route.
In the embodiment of the invention, the longitude and latitude sequence data obtained after conversion is used for drawing a vehicle track broken line superposition layer on a map page according to the time sequence and by adopting the function of creating the broken line covering object of the map, thereby constructing the historical track route of the vehicle. Then, a road book function of the map is called, and a vehicle track playback route covering the historical track route is generated.
Step S3, a play progress bar is established.
In the embodiment of the invention, the playing progress bar is established and displayed at the lower end of the map page, and the physical width value of the playing progress bar is set to be equal to that of the map page. In other alternative embodiments, the playing progress bar may also be established and displayed at other positions of the map page, and the physical width value may also be smaller than the physical width value of the map page, which may be set according to an actual situation, which is not limited herein.
And step S4, acquiring the number of track points played currently during vehicle track playback and the total number of track points of the vehicle track playback route.
It should be noted that the currently played track point refers to a track point corresponding to a route already played in a historical route when the vehicle track is played back, and the total number of track points refers to the number of all track points in the vehicle track playback route. Specifically, when the vehicle track is played back, the current real-time playing position of the vehicle track playback route is obtained through the road book function of the map system, the current playing track point corresponding to the real-time playing position is confirmed, the number of the currently played track points is confirmed according to the current playing track point, and in addition, when the vehicle track playback route is played, the number of the currently played track points is changed accordingly.
Furthermore, in order to facilitate the user to distinguish the vehicle track playback route corresponding to the played track point from the vehicle track playback route corresponding to the unplayed track point, different marking colors are respectively adopted to distinguish the played track point from the unplayed track point, for example, the vehicle track playback route corresponding to the currently played track point is marked with purple, and the vehicle track playback route corresponding to the unplayed track point is marked with gray, so that the user can distinguish conveniently.
And step S5, calculating to obtain the progress value of progress bar by combining the number of currently played track points, the number of total track points and the physical width value of the progress bar, and synchronously assigning the progress value to the progress bar.
Specifically, after the progress value is calculated and obtained, the progress value is synchronously given to the progress bar, so that synchronization between the progress bar and vehicle track playback is completed. For example, assuming that the physical width value of the entire map page is 1360px, in this embodiment, the physical width of the established progress bar is equal to the physical width of the map page, that is, the width of the physical width value of the progress bar in the display screen is also 1360px, the number of track points currently played when the vehicle track is played back is 100, and the total number of track points of the vehicle track playback route is 1000, then it can be calculated that the progress value is (100/1000) × 1360 ═ 136px, and the progress value is assigned to the progress bar, at this time, the playing pointer on the progress bar is positioned to the point indicated by 136px on the physical width of the progress bar. When the vehicle track playback route is played in real time, a new progress value is calculated in real time according to the change of the number of track points which are played at present, and the progress value is given to a progress bar, so that the progress bar and the vehicle track playback are synchronous.
In the embodiment of the invention, a vehicle historical track route is constructed on a map page according to longitude and latitude sequence data in a preset time period in a vehicle historical travel, and a vehicle track playback route is generated; and then establishing a progress bar, calculating the advancing progress value of the progress bar according to the number of the played track points, the total number of the track points and the physical width value of the progress bar during the playback of the obtained vehicle track, and assigning the progress value to the progress bar, so that the synchronization of the vehicle track playback and the playing progress bar in a map system is realized, a user can change the playing position of the vehicle track playback by controlling the progress bar, the track playback efficiency is improved, further, the historical driving information of the vehicle such as the historical driving path and the like can be checked, and the method plays an important role in the subsequent processing of the accident.
Further, in order to facilitate the user to further control the vehicle track playback process through the progress bar, in some embodiments, as shown in fig. 2, after step S5, the method further includes:
and step S10, receiving the progress bar jumping point instruction and acquiring the jumping target point on the progress bar.
Specifically, the user may input a progress bar skip point instruction by clicking or dragging the progress bar with a mouse.
In step S11, a target progress value corresponding to the target point is obtained.
Specifically, after a target point jumped on the progress bar is obtained, a corresponding target progress value on the progress bar is confirmed through the position of the target point. Specifically, referring to fig. 3, after the target point on the progress bar is obtained, the horizontal clientX value of the target point is obtained first. In the embodiment of the invention, a side boundary line of a browser page (or a current window) of a map presenting system in the direction opposite to the starting point of the progress bar is taken as a horizontal coordinate origin, the width between the starting point of the progress bar and the horizontal coordinate origin is set as a frame width value of the browser page (or the current window) of the map presenting system, and the clientX value and the frame width value are subtracted to obtain a width value from a target point to the starting point of the progress bar, namely a target progress value. In addition, when the map system runs, if the map display page completely covers the browser page, that is, the frame width value of the browser page is 0, and the physical width value of the progress bar is equal to the physical width value of the map page, the clientX value is equal to the target progress value.
And step S12, combining the target progress value and the total track point number, and calculating to obtain the number of played track points corresponding to the target point.
Specifically, the number of played track points corresponding to the target point is calculated by combining the target progress value with the progress bar physical width value and the total track point number, where the number of played track points is (target progress value/progress bar physical width value) × the total track point number. For example, by clicking a certain target point on the progress bar with the mouse, a clientX value of the mouse clicked target point may be obtained, assuming that clientX is 700px, a border width of a browser page (or a current window) of the map system is 200px, a physical width value of the map page is 1000px, and in addition, a total number of track points is 1000, in this embodiment, a physical width value of the progress bar is equal to a physical width value of the map page, and if the physical width value of the progress bar is equal to the physical width value of the map page, a target progress value is 700px-200px of the border width of the browser page (or the current window), and if the target progress value is 500px of the border width of the browser page (or the current window), a number of track points already played (target progress value/physical width value of the progress bar) is 1000 (500/1000), which indicates that a 500 th track point in the track point sequence should be played currently
And step S13, obtaining the target track point of the track point sequence according to the number of the played track points, and jumping to the target track point for playing the vehicle track playback route.
Finding a target track point in the track point sequence according to the number of the played track points, and then obtaining the longitude and latitude coordinates of the target track point; and skipping the vehicle track playback route to a target track point, namely playing the longitude and latitude coordinates. Taking the number of the played track points obtained in the foregoing embodiment as 500 as an example, finding a 500 th track point from the track point sequence arranged according to the time sequence, where the point is a target track point; and acquiring the longitude and latitude coordinates of the 500 th track point, and then jumping to a target track point by the vehicle track playback route, namely playing the corresponding longitude and latitude coordinate position of the target track point. In this embodiment, after receiving a progress bar jump point instruction input by a user, a target track point corresponding to a target point where the progress bar jumps is calculated, and a vehicle track playback route is controlled to jump to the target track point for playing, so that the user can directly control the vehicle track playback process through the progress bar.
Further, the user may also set the play speed of the vehicle track during playback, and therefore, in other embodiments, as shown in fig. 4, after step S5, the method further includes:
in step S20, a playback multiple speed value and a preset initial playback speed value are obtained.
And step S21, adjusting the traveling speed of the progress bar according to the playing double-speed value and the initial playing speed value.
It should be noted that the initial play speed value is preset, and the play speed value is input by the user, for example, by providing multiple speed levels for the user to select, such as 1x, 4x, 16x, and 32x, where 1x is the initial play speed value and 4x is the quadruple initial play speed value. Specifically, for example, assuming that the initial play speed value is 10 m/s and the play double speed value is 4x, the travel speed of the progress bar is 40 m/s.
In the embodiment, the traveling speed of the progress bar is adjusted according to the playing double-speed value and the initial playing speed value input by the user, so that the user can control the playing speed during the vehicle track playback, the user can conveniently and quickly check the vehicle track playback, and the time is saved.
