Claim 3:
4. The indoor localization method of claim 2, wherein the step (b):
calculates the global features using a deep learning module that has been subjected to learning in advance so that a same global feature is outputted for images captured the same place, and
wherein the deep learning module comprises:
one or more neural network modules;
a similarity determination module configured to calculate similarities of values outputted from the neural network modules;
a weight module configured to apply weights to the calculated similarities and based on this, to output result values; and
a feedback module configured to derive a difference value between result values outputted at different time points from the weight module, and to provide the derived difference value as feedback to the neural network modules.
