METHOD FOR CONSTRUCTING INDOOR MAP AND RELATED APPARATUS - A simplified explanation of the abstract

This abstract first appeared for US patent application 18423076 titled 'METHOD FOR CONSTRUCTING INDOOR MAP AND RELATED APPARATUS

Simplified Explanation

The method disclosed in this patent application involves constructing an indoor map by obtaining first tracks and a second track, performing layering on the first tracks based on wireless signal information similarity, and obtaining a layering result that can be used to construct the indoor map.

  • Obtaining first tracks and a second track
  • First tracks are flat-layer tracks on an indoor horizontal layer
  • Second track is a cross-layer track between different indoor horizontal layers
  • Wireless signal information similarity between first track points and second track points is less than a first threshold
  • Performing layering on the first tracks based on wireless signal information similarity
  • Obtaining a layering result for constructing an indoor map

Potential Applications

This technology could be used in indoor navigation systems, location-based services, and asset tracking within indoor environments.

Problems Solved

This technology solves the problem of accurately mapping indoor spaces, especially in complex multi-level buildings where traditional mapping methods may be insufficient.

Benefits

The benefits of this technology include improved indoor navigation, enhanced location-based services, and more efficient asset tracking within buildings.

Potential Commercial Applications

A potential commercial application of this technology could be in the development of indoor mapping software for use in shopping malls, airports, hospitals, and other large indoor facilities.

Possible Prior Art

One possible prior art for indoor mapping technology is the use of Wi-Fi fingerprinting and trilateration techniques to determine indoor location. Another prior art could be the use of Bluetooth beacons for indoor positioning and navigation.

Unanswered Questions

How does this technology handle changes in the indoor environment that may affect wireless signal information similarity over time?

The patent application does not specifically address how the method adapts to changes in the indoor environment that could impact the wireless signal information similarity between tracks.

What are the limitations of this technology in terms of mapping accuracy and coverage within indoor spaces?

The patent application does not provide information on the potential limitations of the method in terms of mapping accuracy in complex indoor environments or the coverage of different types of indoor spaces.


Original Abstract Submitted

This application disclose a method for constructing an indoor map. The method includes: obtaining a plurality of first tracks and a second track, where 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, and a first wireless signal information similarity between each first track point of the first track and each second track point is less than a first threshold; and performing layering on the plurality of first tracks based on a second wireless signal information similarity between the plurality of first tracks, to obtain a layering result, where the layering result may be used to construct an indoor map.
