Embodiment 1

[0063] Please see figure 1 , figure 1 It is a flow chart of a multi-floor positioning method provided by the embodiment of the present application.

[0064] This method is applied to the robot, and the position of the robot is located by judging the probability of the WIFI signal strength obtained by the robot in each grid cell. The method specifically may include the following steps:

[0065] Step S100: Obtain the WIFI data information of the robot's current environment;

[0066] For example, the robot may capture WIFI data information in the environment by using data packets in the 802.11 protocol format in the wireless local area network, and the WIFI data information includes a MAC address and a corresponding signal strength RSS. Depending on the location of the robot, the obtained signal strength will also vary. Based on the WIFI data information of the current environment captured by the robot, the location of the robot can be determined.

[0067] Step S200: Input th...

Embodiment 2

[0118] The embodiment of the present application also provides a multi-floor positioning system, such as Figure 7 As shown, it is a structural block diagram of the multi-floor positioning system provided by the embodiment of the present application. The system can include:

[0119] The WIFI data information acquisition module 100 is used to acquire the WIFI data information of the current environment of the robot;

[0120] A probability distribution acquisition module 200, configured to input the WIFI data information into a preset probability distribution model, so as to obtain the probability distribution of each grid cell in each floor map;

[0121] The position information acquisition module 300 is configured to acquire the position information of the robot according to the probability distribution of the WIFI data information in each grid cell in each floor map.

[0122] Exemplarily, the WIFI data information includes MAC addresses and multiple signal strengths corresp...

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...
