Embodiment Construction

[0067] Reference will now be made in detail to the exemplary embodiments, examples of which are illustrated in the accompanying drawings. When the following description refers to the accompanying drawings, the same numerals in different drawings refer to the same or similar elements unless otherwise indicated. The implementations described in the following exemplary examples do not represent all implementations consistent with the present invention. Rather, they are merely examples of apparatuses and methods consistent with aspects of the invention as recited in the appended claims.

[0068] figure 2 It is a flowchart of a method for viewing a track according to an exemplary embodiment of the present invention. The method in this embodiment can be used in equipment such as mobile phones, tablet computers, desktop computers, laptop portable computers, vehicle-mounted computers, servers, driving recorders, and navigators.

[0069] see figure 2 As shown, the method may incl...

Abstract

An embodiment of the invention provides a track viewing method and device. The method comprises the following steps of obtaining multiple coordinate point data of a moving object, wherein each coordinate point datum comprises coordinate point position information and time information corresponding to the position information; generating a track of the moving object according to the position information of the multiple coordinate point data; obtaining an icon corresponding to the moving object; and representing the moving object with the icon, and according to the time information of the multiple coordinate point data, reproducing a motion process of the moving object on the track. The method is not used for simply displaying a track curve merely but reproducing, along the track curve, thereal motion process of the moving object; and in this way, even though a complicated path is met and abnormal points (namely repeated track points, such as a track interlaced point or a track overlapped point) are met in the track, a user can still clearly know a real running process, and thus, masters a precise movement track of the moving object.

Description

technical field [0001] Embodiments of the present invention relate to the technical field of traffic information and image display, and in particular to a method and device for viewing a trajectory. Background technique [0002] With the development of science and technology, more and more vehicles are equipped with positioning devices such as GPS (Global Positioning System, Global Positioning System), so that the location information of the vehicle can be displayed on a map. In the prior art, in order to further display the driving trajectory of the vehicle on the map, the longitude and latitude data information uploaded by the vehicle can be marked as corresponding trajectory points on the map according to a certain time interval, and then many trajectory points within a period of time can be used Lines are connected to obtain a curve, which is the trajectory of the vehicle. The user can look back (or replay, play) the trajectory curve on the screen, so as to achieve moni...
