MAP MANAGEMENT APPARATUS - A simplified explanation of the abstract

This abstract first appeared for US patent application 18524775 titled 'MAP MANAGEMENT APPARATUS

Simplified Explanation: The patent application describes a map management app that uses image recognition to identify road features and speed signs, compares this information with map data, and prompts for map updates if discrepancies are found.

  • Image recognition unit identifies road shape, type, and speed signs from in-vehicle camera images.
  • Recognition determination unit compares recognized information with map data.
  • Vehicle speed determination unit compares own vehicle speed with speed sign information in maps.
  • Notification unit prompts for map updates if discrepancies in recognition and vehicle speed occur frequently.

Key Features and Innovation:

  • Utilizes image recognition to identify road features and speed signs.
  • Compares recognized information with map data for accuracy.
  • Prompts for map updates based on frequent discrepancies in recognition and vehicle speed.

Potential Applications: The technology can be used in navigation systems, autonomous vehicles, and road maintenance applications.

Problems Solved: Addresses the need for accurate and up-to-date map information for navigation and road safety.

Benefits: Improves navigation accuracy, enhances road safety, and ensures timely updates to map data.

Commercial Applications: This technology can be applied in GPS navigation devices, fleet management systems, and smart city infrastructure.

Prior Art: Potential areas to explore for prior art include image recognition in navigation systems, map data management tools, and speed sign detection technologies.

Frequently Updated Research: Stay informed about advancements in image recognition, map data accuracy, and autonomous vehicle technologies.

Questions about Map Management Apparatus: 1. How does the image recognition unit identify road features and speed signs accurately? 2. What are the potential challenges in integrating this technology into existing navigation systems?


Original Abstract Submitted

A map management apparatus includes an image recognition unit that recognizes at least any one of a road shape, a road type, and a speed sign on the basis of a captured image of an in-vehicle camera, a recognition determination unit that determines whether or not there is a difference between the recognized recognition information and map information, a vehicle speed determination unit that determines whether or not there is a difference between a speed of an own vehicle and speed sign information included in the map information, and a notification unit that issues a notification for prompting update of the map information when the number of times when the recognition determination unit determines that there is the difference and the vehicle speed determination unit determines that there is the difference becomes equal to or more than a determination frequency threshold.
