Abstract

The invention provides a satellite positioning track smoothing method and device. The method comprises the following steps: building a target processing model; processing the coordinate sequence of the to-be-processed track according to the target processing model to obtain the removal probability of each coordinate on the to-be-processed track; and carrying out smoothing processing on the to-be-processed track according to the removal probability through a dichotomy model. According to the smoothing method of the satellite positioning track, noise points and redundant points in the satellite positioning track can be accurately and effectively removed based on machine learning and based on big data, a tedious calculation formula cannot be adopted, and the method is relatively simple.

Description

technical field [0001] The invention relates to the technical field of trajectory smoothing processing, in particular to a method and device for smoothing a satellite positioning trajectory. Background technique [0002] The trajectory of the entity (which can represent objects such as vehicles or people) based on the satellite positioning system not only provides the basis for the visualization of the trajectory of the entity, but also provides the basis for mileage calculation and even billing. However, no matter what kind of satellite positioning system is used, many factors may lead to extreme positioning errors (commonly known as positioning drift), and such errors will cause some track points in the entity's motion track to be obviously inconsistent with the actual situation. [0003] In related technologies, most of the fixed calculation formulas are used to correct the physical trajectory generated by the satellite positioning system, and the calculation results of t...
