Abstract
The present invention relates to a method of correcting positioning position error. The method belongs to the network positioning technology field, and aims to solve the problems that a network positioning error is larger, and a theory error can reach 500 to 1000 meters, and to improve the accuracy of network positioning. A technology for correcting the positioning error comprises firstly obtaining an original latitude and longitude via a device, wherein the offset of the latitude and longitude is generally larger. The first time error correction is finished by using an offset database of the Google. The Google is a foreign company, and does not have the complete data about WIFI hot spots and mobile base stations, so that the error of the original latitude and longitude is corrected again by utilizing an offset database of the Baidu, and then the relative relationship of the twice error correction and the original latitude and longitude is compared, if the twice error correction are in the same direction, a calculated offset value is corrected again in the original orientation, if the twice error correction are in the reverse directions, a new offset value is calculated in the range of the twice error correction, and then the original latitude and longitude is corrected, and accordingly, the accuracy of the network positioning is improved substantially.
Description
Technical field
The position location method of rectifying a deviation is a kind of method for correcting error that is applied in the network positions based on cellular base station and WIFI focus, and this method for correcting error can be used for mobile device and PC computer.
Background technology
How to obtain user's accurate location? this difficult problem is the problem that first LBS field will solve.Because technical limitations, traditional gps satellite location only has outdoor open space accurately to locate, and for indoor environment, GPS location tends to cannot locate because of " searching star " failure.Just because of the natural defect of GPS location, the location technology based on cellular base station and WIFI focus is just flourish.But because the coverage of base station is large, be difficult to obtain high-precision effect, this method for correcting error, has proposed a method that improves wireless network positioning precision.
Summary of the invention
In order to improve the availability of network positions, the precision that improves network positions is the most important thing.This method for correcting error combines the correction algorithm of each large GIS-Geographic Information System, and the longitude and latitude navigating to is carried out to secondary correction, has improved the accuracy of location.
First this method for correcting error obtains original longitude and latitude by equipment, then by the correction database of Google, original longitude and latitude is once rectified a deviation, obtain the longitude and latitude of Google, and then by the correction database of company of Baidu, original longitude and latitude is once rectified a deviation, obtain the longitude and latitude of company of Baidu.Have after three groups of longitudes and latitudes, drawn cartesian coordinate system take original longitude and latitude as initial point, then the longitude and latitude of the longitude and latitude of Google and company of Baidu has been labeled on this coordinate system, judged the relativeness of the longitude and latitude of Google and the longitude and latitude of Baidu.First draw a vertical line with the large value of the latitude of Google's longitude and latitude and the latitude of Baidu's longitude and latitude, again with horizontal line of large value picture of the longitude of Google's longitude and latitude and the longitude of Baidu's longitude and latitude, obtain a rectangle by the focus of two lines, then draw two diagonal of rectangle, if the four edges of rectangle has any two limits simultaneously by Google's longitude and latitude and Baidu's longitude and latitude, the longitude and latitude at two cornerwise intersection point places is exactly the longitude and latitude after correction so.If Google's longitude and latitude or Baidu's longitude and latitude are summits of rectangle, so again with original longitude and latitude by Google's longitude and latitude and Baidu's longitude and latitude, be not summit that group longitude and latitude draw a ray, ray can form an intersection point with a wherein diagonal of rectangle, and the mid point of the line segment of this intersection point and two cornerwise intersection point formation is through latitude after correction.
Embodiment
Method for correcting error is with javascript language development, the program that can move in kinds of platform.
