Abstract

The invention discloses an indoor map positioning method based on a dynamic word vector. According to inertial sensor data and map information, a deep learning framework based on the dynamic word vector is designed and built, intelligent extraction of the map information is completed, and an indoor map matching positioning technology is achieved. The indoor map positioning method has the advantages that the map information can be fully utilized, and the scene generalization performance is high, and is particularly suitable for scenes with complex indoor spaces.

Description

technical field [0001] The invention relates to the field of indoor positioning methods, in particular to an indoor map positioning method based on dynamic word vectors. Background technique [0002] As people's demand for indoor location services is increasing, the role of accurate and efficient indoor positioning technology has become a rigid demand for indoor location services. In the outdoor environment, the global navigation satellite system (GNSS) provides users with meter-level location services, which basically solves the problem of accurate positioning in outdoor spaces, and has been widely used in daily life. However, affected by the occlusion of buildings and the multipath effect, the GNSS positioning accuracy drops sharply and cannot meet the needs of indoor location services. However, the urgent needs of indoor positioning in some specific occasions have become increasingly significant. Therefore, indoor positioning technology has become the focus of experts and...
