Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for extracting a crop area from a vehicle's forward-view image for augmented reality driving information display are inaccurate due to temporary changes in camera pose values caused by vehicle conditions, leading to unstable and inconvenient information presentation.
Innovation Solution
A driving information display apparatus and method that corrects camera pose values using a vanishing point, setting the crop area at its center by continuously updating pitch, yaw, and roll values based on recognized lane intersections and horizon, ensuring stable extraction of the forward area.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If camera pose values are used to extract crop area for augmented reality display, then driving information can be provided overlaid on forward-view image, but the extracted area is unnecessarily altered due to temporary changes in camera pose values caused by vehicle conditions
Solution Approach 1:
The system continuously monitors camera pose values and compares them against reference values or acceptable ranges. When temporary deviations are detected due to vehicle conditions, the feedback mechanism triggers correction processes that adjust the crop area extraction parameters, ensuring stability while adapting to actual camera position changes
Solution Approach 2:
The crop area extraction system is designed to dynamically adjust to camera pose changes by implementing a correction mechanism that distinguishes between temporary deviations and permanent position changes, allowing the system to maintain stable extraction during normal operation while adapting to actual structural changes in camera mounting
2Productivity
If crop area is extracted based on initial camera pose values, then augmented reality driving information can be displayed, but the information presentation becomes unstable and inconvenient due to pose value changes
Solution Approach 1:
The system performs preliminary correction of camera pose values by establishing reference values during a calibration phase or by using multiple measurement samples to determine average pose values. This preliminary action ensures that subsequent crop area extraction is based on accurate, stabilized reference data, preventing instability in information presentation
Solution Approach 2:
The system implements error compensation mechanisms that anticipate and counteract the effects of camera pose variations. By pre-calculating correction factors and establishing tolerance ranges, the system cushions against the impact of pose value changes, maintaining reliable information presentation even when temporary deviations occur

AI summary
A driving information display apparatus and method corrects camera pose values using a vanishing point. The apparatus includes a processor configured to receive driving guidance and vehicle location information, control the output of a guidance screen, and set a crop area in an image from a forward-view camera based on the calculated vanishing point. The storage unit stores road information, algorithms, and camera pose values, allowing the processor to generate a guidance screen by integrating the driving guidance information within the crop area centered on the vanishing point.
