Method, device, terminal and computer-readable storage medium for smoothing map trajectory

Abstract

The invention discloses a map track smoothing method, a device, a terminal and a computer-readable storage medium, which relate to the map application technical field and are used for solving the problem that the error between the smoothly processed track points and the actual positioning points in the existing map track is too large. The invention also discloses a map track smoothing method, a terminal and a computer-readable storage medium. The method comprises the following steps of: acquiring the track points after smoothing processing; According to the positioning points corresponding toeach locating point and the positioning accuracy corresponding to each locating point, the locating points are corrected and the correcting points are obtained to generate map trajectories by using the correcting points; According to the positioning point corresponding to each track point and the positioning accuracy corresponding to each positioning point, Correcting the trajectory points, obtaining the corrected points and using the positioning accuracy of the locating points before smoothing to correct the trajectory points. According to the invention, the problem that the error between thesmoothed trajectory points and the actual locating points is too large can be effectively solved and the user experience under the premise of ensuring the smoothness of the trajectory is improved.

Description

technical field [0001] The present invention relates to the field of map application technology, in particular to a method, device, terminal and computer-readable storage medium for smoothing map tracks. Background technique [0002] With the development of science and technology in modern society, people are getting more and more mobile devices with positioning functions such as smart bracelets, smart watches, trackers and drones. In the process of using the above-mentioned mobile devices, it is often necessary to display the map track of the mobile device on a mobile terminal device, for example, the supporting app on the mobile phone can be used to display the flight track of the paired drone. [0003] For the map track, the track points on the map track usually come from the positioning points in the positioning data (such as GPS data) obtained by the mobile device. Due to the error of the positioning point itself, the reporting frequency of the positioning point is also...
