Abstract

The invention relates to an indoor and outdoor cooperative positioning method based on Beidou. The method comprises the following steps: enabling a mobile terminal to carry out out periodic scanning to obtain positioning information; selecting WiFi beacons and constellations according to a cost function and a normalization function, and determining Beidou and the WiFi beacon; and obtaining the position of the terminal based on an equation of Beidou and WiFi fusion. According to the invention, indoor and outdoor cooperative positioning can be effectively realized.

Description

technical field [0001] The invention relates to the technical field of positioning, in particular to a Beidou-based indoor and outdoor collaborative positioning method. Background technique [0002] With the rapid development of the Internet and the continuous enrichment of terminal applications, the development of positioning technology has been greatly promoted. At present, the most widely used positioning method is to realize positioning based on the global navigation satellite system. [0003] The satellite navigation system is an important spatial information infrastructure for every country. With the continuous development and update of the satellite system, the quality of the broadcast signal and the improvement of the global satellite constellation, its positioning technology is also constantly innovating. Our country focuses on national security and The improvement of the economic level attaches great importance to the Beidou satellite navigation system. Compared wi...
