Example Embodiment
[0045] Example 1:
[0046] A Wi-Fi indoor positioning method based on deep learning:
[0047] Establish fingerprint database:
[0048] 1) Sample RSS data collection.
[0049] 1-1) Deploy n Wi-Fi wireless access points (APs) in indoor areas that need to be positioned.
[0050] 1-2) Divide the indoor area into m domain blocks, where m is a natural number.
[0051] Take the center of each domain block as the sampling point P k , Measure the received signal strength RSS of each APs deployed in step 1-1), each sampling point P k All correspond to one position coordinate, and n RSS data corresponding to one position coordinate form a row of the multidimensional data sample set R after sorting. k=1, 2...m.
[0052] 2) Data preprocessing, completion and normalization.
[0053] 2-1) Add missing zeros to the multidimensional data sample set R obtained in step 1).
[0054] 2-1) Normalization processing, the training set H is obtained.
[0055] 3) Deep feature learning.
[0056] Build a deep feature lea...
Example Embodiment
[0076] Example 2:
[0077] In this embodiment, the method described in Embodiment 1 is applied to the positioning of parking spaces in a large-scale complex indoor parking garage.
[0078] It is worth noting that for large indoor parking garages, finding vehicles has always been a difficult problem to solve. Existing technology (if attached Image 6 As shown), a camera and a license plate recognition system are installed in each parking space to record the parking position of the vehicle. Although this approach solves the above problems, the cost of installing the camera is very high, and the post-maintenance cost and reliability of the camera are not ideal.
[0079] This embodiment discloses a method for finding the parking position of a vehicle:
[0080] Establish fingerprint database:
[0081] 1) Sample RSS data collection.
[0082] 1-1) such as figure 1 As shown, n Wi-Fi wireless access points (APs) are deployed in an indoor garage.
[0083] 1-2) Divide the indoor area into m doma...
