Map Information Accuracy Assessment for Autonomous Vehicles
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current methods for generating map information for autonomous traveling vehicles lack a way to ascertain the accuracy of the map information, making it difficult for users to determine its appropriateness.
Innovation Solution
An information processing device that includes a sensor information acquisition unit, a map information generation unit, a map appropriateness estimation unit, and a notification unit, which acquires sensor information, generates map information, estimates the appropriateness of the map information based on detection reliability or distribution of feature points, and notifies the user of the appropriateness through graphical or sensory feedback.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If map information is generated manually using sensors or automated methods, then map information can be created for autonomous traveling vehicles, but there is no way to ascertain whether the map information is appropriate in terms of accuracy
Solution Approach 1:
The patent implements a feedback mechanism by introducing a map appropriateness estimation unit that evaluates the quality of generated map information and a notification unit that communicates this evaluation to the user. This closed-loop feedback system allows users to ascertain the accuracy of map information, directly resolving the contradiction between generating map information and providing awareness of its appropriateness.
2Productivity
If automated methods are used to generate map information, then productivity is improved, but the user cannot determine the appropriateness of the generated map information
Solution Approach 1:
The notification unit provides feedback to users about the appropriateness of automatically generated map information, enabling users to assess the reliability of the generated content without manual verification, thus maintaining high productivity while improving user confidence.
Solution Approach 2:
The map appropriateness estimation unit enables the system to self-evaluate the quality of its own generated map information, allowing automated methods to not only generate maps efficiently but also to assess their own reliability, resolving the contradiction between automation and user confidence.
3Measurement precision
If manual methods are used to generate map information, then accuracy can be controlled, but productivity and efficiency are reduced
Solution Approach 1:
The automated map generation system performs self-verification through the map appropriateness estimation unit, which automatically evaluates the quality of generated maps. This eliminates the need for manual accuracy verification while maintaining high generation speed, thus improving productivity without sacrificing accuracy control.
