Embodiment Construction

[0048] Since the existing indoor positioning technology cannot effectively compensate for the attenuation of the wireless signal blocked by the user's human body or other obstacles, the positioning accuracy is not high. The embodiment of the present invention judges by comparing the electronic map with the wireless signal. The user's movement orientation, through the judgment of the relative position of the user and the wireless positioning terminal, can compensate the wireless signals of the beacon nodes in different directions in a targeted manner, so that it can effectively solve the problem of the user's human body or other obstacles affecting the wireless signal. The problem of blocking attenuation can improve the positioning accuracy.

[0049] The solutions provided by the embodiments of the present invention are not limited to the application of indoor positioning technology, and the solutions provided by the embodiments of the present invention can also be applied outdo...

Abstract

The invention discloses an indoor wireless positioning method and an indoor wireless positioning device. The method comprises the following steps of: calibrating a coordinate and a direction on an electronic map, and recording the position of each beacon node; determining the position coordinates of a wireless positioning terminal at the present moment according to the orientation value which is acquired by the wireless positioning terminal via an electronic compass at the present moment and the positioning result of the last moment; compensating the acquired wireless signals according to the position coordinate and the position of each beacon node; and calculating to obtain the positioning result according to the value of the compensated wireless signals. By the scheme provided by the invention, the directional sensitivity of positioning result to the user movement can be reduced, the positioning error is effectively reduced, and the positioning precision is improved. Simultaneously, by the scheme provided by the embodiment of the invention, the positioning matching range can be reduced, the positioning time can be shortened, user experience can be improved, and the smoothness of dynamic real-time tracking under movement state is further improved.

Description

technical field [0001] The present invention relates to the technical field of wireless positioning, in particular to an indoor wireless positioning method and device. Background technique [0002] With the continuous expansion and deepening of Internet of Things applications, location-aware computing (LAC, Location-aware Computing) and location-based services (LBS, Location-based Services) are becoming more and more important. Without location information, perception data has lost its application value. [0003] The emergence and development of satellite navigation and positioning technology, which is widely used at present, has enabled people to have a technical method to obtain the spatial location attributes of things in the vast outdoor space around the world, and has been used in military, transportation, resource environment, agriculture, animal husbandry, fishery, surveying and mapping and other fields. And it has been widely used in people's daily life. But in act...
