Problems solved by technology
[0002] At present, the construction environment of highways and railways is difficult and harsh, the risk factor of the type of work is high, and the number of workers is large, which makes the protection work of railway construction personnel face great difficulties. A positioning method with high positioning accuracy is urgently needed. However, the current railway construction Personnel generally use a single GPS measurement method or a general differential GPS positioning method. This positioning method is greatly affected by the environment and satellite changes, and the positioning accuracy is low.

The present invention discloses a location method and device, belonging to the technical field of location. The method comprises the steps of: obtaining a moving track of a target object, performing filtering processing for the moving track of the target object, and fitting the moving track of the target object after filtering processing and a reference track to obtain an actual moving track of the target object. According to the embodiment of the invention, after the moving track of the target object is obtained, the filter is employed to perform filtering for the moving track of the target object to filter errors caused by environmental disturbance and improve the location precision of the moving track of the target object, the moving track after filtering and the reference track are fitto correct the obtained moving track of the target object so as to further improve the location precision.
Description
technical field [0001] The present invention relates to the technical field of positioning, in particular to a positioning method. Background technique [0002] At present, the construction environment of highways and railways is difficult and harsh, the risk factor of the type of work is high, and the number of workers is large, which makes the protection work of railway construction personnel face great difficulties. A positioning method with high positioning accuracy is urgently needed. However, the current railway construction Personnel generally use a single GPS measurement method or a general differential GPS positioning method. This positioning method is greatly affected by changes in the environment and satellites, and the positioning accuracy is low. Contents of the invention [0003] An embodiment of the present invention provides a positioning method, aiming at improving the positioning accuracy of a target object. In order to provide a basic understanding of s...
