Embodiment Construction
[0018] A method for indoor positioning and navigation based on Wi-Fi, comprising an acquisition phase, an online positioning, and a navigation phase, specifically comprising the following steps:
[0019] S1. Acquisition stage: including fingerprint collection and fingerprint clustering. Complete the database establishment of RSS fingerprint collection of each reference point in the same direction in the positioning area, preprocess the collected database through affine propagation clustering, form different classes, and Form a class leader and a corresponding received signal strength vector in the fingerprint library;
[0020] S2. Online positioning: including coarse positioning and fine positioning. Through the matching between the collected online RSS vector and the RSS vector of each class leader in the fingerprint database, the server sends the matched part of the fingerprint information to the handheld terminal. Through the improved Compressed sensing model, handheld term...
