Lane Recognition Synchronization via Reliability Evaluation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing lane recognition systems experience variations in recognizing left and right lane lines, leading to discomfort for drivers due to differences in recognition timing, especially when lane line positions shift or one line is about to disappear, causing uneven display timing and potential misrecognition of patterns like snow.
Innovation Solution
A lane recognition apparatus that includes a lane recognizer, a reliability evaluator, and a recognition state monitor, which evaluates the reliability of lane line recognition based on characteristic amounts and adjusts the display timing of recognition results to ensure synchronized display of left and right lane lines, preventing driver discomfort by synchronizing the display of lane lines once both are recognized.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the system waits for reliable recognition of both lane lines before displaying, then recognition accuracy improves, but display timing synchronization deteriorates when one line is recognized faster than the other
Solution Approach 1:
The system performs preliminary recognition of lane lines and evaluates their reliability in advance. When both left and right lane lines are recognized with sufficient reliability, the system displays them simultaneously. This preliminary evaluation allows the system to prepare display data before actual display, ensuring both reliability and timing synchronization.
Solution Approach 2:
The system dynamically adjusts the display timing based on the recognition status of both lane lines. When one lane line is recognized faster than the other, the system holds the display until both are ready, creating a dynamic waiting mechanism that ensures synchronization without compromising recognition reliability.
2Speed
If the system displays lane lines as soon as they are recognized, then display responsiveness improves, but recognition accuracy deteriorates due to insufficient evaluation time
Solution Approach 1:
The system performs preliminary recognition and reliability evaluation of lane lines before displaying them. This preliminary action ensures that only reliably recognized lane lines are displayed, maintaining high recognition accuracy while still achieving responsive display timing through efficient pre-processing.
3Reliability
If the system uses multiple characteristic amounts for evaluation, then recognition accuracy improves, but processing time increases
Solution Approach 1:
The system evaluates multiple characteristic amounts (color, shape, position, continuity) of lane lines to ensure high recognition accuracy. By comprehensively analyzing these multiple attributes, the system achieves reliable lane line recognition even in challenging conditions, accepting the necessary processing time as a trade-off for accuracy.

AI summary
A lane recognition apparatus includes a lane recognizer, a lane evaluator, and a recognition state monitor. The lane recognizer recognizes lane lines of a road on which a vehicle travels. The lane lines include a first lane line and a second lane line. The lane evaluator evaluates, as recognition reliability, reliability of the recognition of the lane lines recognized by the lane recognizer, based on a plurality of characteristic amounts that are obtained from the recognition of the lane lines. The recognition state monitor monitors, upon completion of the recognition of the first lane line following the evaluation on the recognition reliability, a state of the recognition of the second lane line to adjust a timing at which a result of the recognition of the lane lines is provided to a driver.
