SERVER AND CONTROL METHOD THEREOF - A simplified explanation of the abstract

This abstract first appeared for US patent application 17975817 titled 'SERVER AND CONTROL METHOD THEREOF

Simplified Explanation

The abstract describes a server system that receives image data from a terminal device and uses it to determine the location of the device. The system compares the received image data with a stored map to find areas with significant differences. It then updates the map with the new image data or requests additional image data from users.

  • The server system receives image data from a terminal device.
  • It determines the location of the terminal device by comparing the image data with a stored map.
  • The system identifies areas where the image data differs significantly from the map.
  • It updates the map and corresponding descriptors based on the received image data.
  • Alternatively, the system can request additional image data from users through crowdsourcing.

Potential Applications

  • Indoor navigation: The system can be used to accurately locate terminal devices within indoor environments, enabling navigation and wayfinding.
  • Augmented reality: By updating the map with new image data, the system can enhance augmented reality experiences by providing real-time information about the environment.
  • Location-based services: The accurate location determination can be utilized for various location-based services, such as targeted advertising or personalized recommendations.

Problems Solved

  • Accurate indoor positioning: The system solves the problem of accurately determining the location of terminal devices within indoor environments, where GPS signals may not be available or reliable.
  • Map updating: By updating the map with new image data, the system addresses the challenge of keeping maps up to date with changes in the environment.
  • Data collection: The system solves the problem of collecting image data for areas where the map data is insufficient or outdated by requesting crowdsourcing.

Benefits

  • Improved navigation: The accurate location determination enables precise indoor navigation, improving user experience and reducing confusion.
  • Real-time updates: By updating the map with new image data, the system provides real-time information about the environment, enhancing augmented reality and location-based services.
  • Efficient data collection: The system efficiently collects image data by leveraging crowdsourcing, ensuring that the map remains up to date without requiring extensive resources.


Original Abstract Submitted

A server includes a communicator; and a controller configured to: when an image data is received from a terminal device through the communicator, determine a first key point of the image data and a first descriptor corresponding to the first key point, determine a location of the terminal device by comparing the first descriptor with a second descriptor stored in a virtual positioning system (VPS) map, determine an area where a difference between the first descriptor and the second descriptor is greater than or equal to a predetermined value based on the location of the terminal device, and update a key point of the area on the VPS map and the second descriptor based on the image data, or request crowdsourcing of an image data about the area.
