A method and device for drawing user trajectory

Abstract

The present invention provides a method and device for drawing a user's trajectory. According to the dotted distance used to draw the user's trajectory, the instantaneous state of the current positioning point where the user is located is obtained, wherein the instantaneous state includes the user's location at the current positioning point. The instantaneous speed, the dotted distance is the distance between every two adjacent positioning points of the user during the drawing process of the user trajectory; the current positioning point of the user is drawn on the map according to the instantaneous state, Therefore, the user trajectory is drawn; according to the instantaneous speed of the user at the current positioning point included in the instantaneous state, the dotted distance used for drawing the user trajectory is adjusted to obtain the adjusted dotted distance. The invention achieves the effect of both density and time display when drawing the user's trajectory, helps the user to obtain a reasonable movement trajectory on the map, and can display the time information during the user's movement on the map in the form of a time axis.

Description

technical field [0001] The invention relates to the field of mobile technology, in particular to a technology for drawing user trajectories. Background technique [0002] Draw the user's movement trajectory on the map through the positioning of the map. You can obtain the user's current location point by time or distance, and draw the user's movement trajectory on the map. [0003] If the user's current positioning point is obtained according to the method of time management, although the display of the time axis is uniform and friendly, but because it is impossible to predict the distance that the terminal moves in a certain period of time, the density of the points on the map will show two levels of differentiation. If you move quickly, you will see broken lines due to the sparse dots, and if you stay for a long time, you will have too many dots and the performance will be dense, which consumes resources and is not conducive to display. [0004] If the user's current posi...

Problems solved by technology

[0003] If the user's current positioning point is obtained according to the method of time management, although the display of the time axis is uniform and friendly, but because it is impossible to predict the distance that the terminal moves in a certain period of time, the density of the points on the map will show two levels of differentiation. Fast movement will show broken lines due to sparse dots, and long-term stay will show too dense dots and dense performance, which consumes resources and is not conducive to display

[0004] If the user's current positioning point is obtained by the distance point, the fixed distance is friendly to the spatial expansion of the map representation, and the map trajectory line segments are even, so that the distribution of points will not be too concentrated or sparse, but because the time is not fixed, it is not friendly to the performance of the time axis. The main performance is that it is impossible to define how long to stay at a certain point, how long to move, abnormal exit definition, etc.
