Vehicle Camera Control for False Road Feature Recognition
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vehicle control systems may erroneously recognize structural objects on the road, such as snow melting pipes or vehicle guide lines, leading to inappropriate vehicle control due to false feature recognition.
Innovation Solution
A vehicle control device that utilizes a memory to store structure and feature information, and a processor to detect and determine if structural objects are erroneously recognized, controlling vehicle travel based on this information to prevent inappropriate control.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If the vehicle control system uses image recognition to detect features around the vehicle, then the ability to identify self-position and control vehicle travel is improved, but the risk of erroneously recognizing structural objects (e.g., snow melting pipes) as predetermined features increases
Solution Approach 1:
The system uses map information as feedback to verify image recognition results. By comparing detected features with predetermined feature information from maps, the system can identify when a structural object has been mistakenly recognized as a feature, and correct the control decisions accordingly
Solution Approach 2:
Map information serves as an intermediary between image recognition and vehicle control. The recognition result is not directly used for control but is first validated against map data, filtering out false recognitions of structural objects before control decisions are made
2Measurement precision
If the vehicle control system corrects self-localization information based on image recognition results, then the positioning accuracy is improved, but the system may execute inappropriate control when false recognition occurs
Solution Approach 1:
The system performs preliminary verification of image recognition results against map information before using them for self-localization correction. This advance check prevents false recognition data from corrupting the positioning information
Solution Approach 2:
The system prepares countermeasures by having map information ready to counteract potential false recognition. When a structural object is misidentified as a feature, the map data provides the correct reference to prevent inappropriate control corrections

AI summary
A vehicle control device includes a memory configured to store structure information indicating a position and a type of a structural object visible from a vehicle traveling in a predetermined road section, and similar relationship information indicating a similar relationship between the structural object and one or more predetermined features which are provided in the predetermined road section; and a processor configured to detect the one or more predetermined features based on an image generated by a camera mounted on the vehicle and representing a situation around the vehicle, determine whether or not the structural object has been erroneously recognized as at least one of the one or more predetermined features detected while the vehicle is traveling in the predetermined road section based on the similar relationship information and the structure information, and control the traveling of the vehicle according to the determination result.
