Method for constructing indoor map and related apparatus

A device comprising:

• a memory configured to store instructions;
• and
• one or more processors coupled to the memory and configured to execute the instructions to cause the device to:
• obtain a plurality of first tracks and a second track, wherein each first track is a flat-layer track located on an indoor horizontal layer, the second track is a cross-layer track located between different indoor horizontal layers, each first track comprises a plurality of first track points, the second track comprises a plurality of second track points, each first track point and each second track point comprise wireless signal information at locations of the first track point and the second track point respectively, and a first wireless signal information similarity between each first track point and each second track point is less than a first threshold;
• perform layering on the plurality of first tracks based on a second wireless signal information similarity between the plurality of first track points comprised in the plurality of first tracks, to obtain a layering result, wherein the layering result comprises a plurality of horizontal layers and at least one of the plurality of first tracks comprised on each horizontal layer, and first tracks whose second wireless signal information similarity is greater than a second threshold are grouped into a same horizontal layer;
• and
• construct an indoor map based on the layering result and the second track whereby the layering result excludes track points near the second track being the cross-layer track.

A computer program product comprising computer-executable instructions stored on a non-transitory computer-readable storage medium, the computer-executable instructions when executed by one or more processors of an apparatus, cause the apparatus to:

• obtain a plurality of first tracks and a second track, wherein each first track is a flat-layer track located on an indoor horizontal layer, the second track is a cross-layer track located between different indoor horizontal layers, each first track comprises a plurality of first track points, the second track comprises a plurality of second track points, each first track point and each second track point comprise wireless signal information at locations of the first track point and the second track point respectively, and a first wireless signal information similarity between each first track point and each second track point is less than a first threshold;
• perform layering on the plurality of first tracks based on a second wireless signal information similarity between the plurality of first track points comprised in the plurality of first tracks, to obtain a layering result, wherein the layering result comprises a plurality of horizontal layers and at least one of the plurality of first tracks comprised on each horizontal layer, and first tracks whose second wireless signal information similarity is greater than a second threshold are grouped into a same horizontal layer;
• and
• construct an indoor map based on the layering result and the second track whereby the layering result excludes track points near the second track being the cross-layer track.
