Abstract

This invention discloses a high-precision indoor positioning method based on ConvNet fingerprint features. First, multiple deep learning features are extracted from the image and constructed hierarchically to form a ConvNet fingerprint feature with strong representational power and high robustness. Then, a high-precision map is constructed based on the ConvNet fingerprint features. Finally, high-precision indoor positioning is achieved by matching deep learning features at different scales. This invention eliminates the need for deploying positioning signal transmitters; high-precision indoor positioning can be achieved solely through images. Compared to existing methods, this method is low-cost and offers high positioning accuracy.
