AI Technical Summary

Technical Problem

Existing spatial image mapping systems struggle to accurately map urban areas with high-rise buildings due to satellite communication interference and costly, infrequent aerial photography, leading to inaccurate and inefficient topographic feature updates.

Method used

A spatial image mapping system using drones equipped with RF transmitters and GNSS receivers, along with a management server, to capture and process images, ensuring precise mapping and frequent updates by identifying RF transmitters and generating coded images for accurate location application.

Benefits of technology

Enables precise mapping of urban areas with changing topographic features using drones, providing reliable and cost-effective periodic image updates, replacing costly and inefficient aerial photography.

Abstract

The present invention relates to a spatial image mapping system, and more specifically, to a spatial image mapping system that improves the precision of mapping using a drone and a captured image, characterized by comprising at least three movable vehicles equipped with an RF transmitter and a GNSS receiver to perform a coordinate reference point function, a drone that identifies each RF transmitter through RF received from the RF transmitter and generates a captured image coded by each RF transmitter according to the shooting zone using coordinate information received from the GNSS receiver, and a management server equipped with a mapping module that receives the captured image generated by the drone and performs mapping.
