Abstract

The embodiment of the invention provides a multi-floor positioning method and system, and relates to the technical field of signal processing. The method comprises the steps of acquiring WIFI data information of the current environment of the robot; inputting the WIFI data information into a preset probability distribution model to obtain probability distribution of each grid unit in each floor map; acquiring position information of the robot according to probability distribution of the WIFI data information in each grid unit in each floor map. The problems that in an existing method, the WIFIpositioning effect is poor, WIFI data sources are manually collected, and consequently the collection efficiency of the WIFI data sources is low are solved.

Description

technical field

[0001] The present application relates to the technical field of signal processing, and in particular, to a multi-floor positioning method and system. Background technique

[0002] The existing robot indoor positioning scheme mainly realizes the positioning of the robot in the indoor environment through the laser and camera data collected in advance with the help of SLAM (Simultaneous Localization And Mapping, real-time positioning and map construction) technology; since the indoor environment does not have GPS and other global The method of positioning in the absolute coordinate system, so the method based on the bag of feature words with the help of visual VSLAM (Visual SLAM) has become the input reference and closed-loop means of global positioning. However, due to the influence of light, this bag of feature words method cannot be applied to all scenes; in addition, in multi-story buildings, the characteristics of the same vertical space on different floor...
