Document Type and Number:
WIPO Patent Application WO/2018/040007
Kind Code:
A1
Abstract:
The present application relates to the technical field of data processing, in particular to a method and device for constructing a wireless positioning feature library. The method comprises: acquiring a wireless positioning training data set, the wireless positioning training data set comprising a plurality of training data; merging and clustering the plurality of training data one by one; determining wireless positioning feature data according to at least one sample data obtained by means of merging; merging and clustering any single training data A comprising: when a preconfigured sample data set comprises at least one sample data, determining sample data positioned in a preconfigured range of the training data A from the at least one sample data; determining sample data B having the highest similarity to the training data A from the sample data positioned in the preconfigured range of the training data A; merging the training data A and the sample data B into a new sample data C; and substituting the sample data B with the sample data C and adding into the sample set. The solution of the embodiment of the present invention can improve accuracy of wireless positioning.
