Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vehicle safety systems, such as Forward Collision Warning (FCW) and Lane Departure Warning Systems, face challenges in processing images in real time due to improved camera performance and static Region of Interest (ROI) settings, leading to reduced driving safety and stability.
Innovation Solution
An apparatus and method that dynamically adjusts the ROI in a forward-view image based on braking and steering information, including moving the ROI position and size according to steering direction and angle, and braking state, to enhance image processing efficiency and accuracy.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a static ROI is used in image processing, then the system structure is simple, but the processing time increases and real-time performance deteriorates
Solution Approach 1:
The patent applies dynamics by making the ROI position and size changeable based on vehicle driving states. The controller dynamically adjusts the ROI region in the forward-view image according to steering information and braking information, transforming the static ROI into a dynamic one that adapts to real-time driving conditions, thereby reducing processing time while maintaining system functionality.
2Stability of the object's composition
If a static ROI is used, then the system is stable, but driving safety and processing efficiency are reduced
Solution Approach 1:
The patent implements feedback by using steering information and braking information as feedback signals to adjust the ROI. The controller receives feedback from the steering information acquisition device and braking information acquisition device, and uses this feedback to dynamically adjust the ROI position and size, ensuring the system responds appropriately to changing driving conditions while maintaining overall stability.
3Quantity of substance
If the ROI is set to an unnecessary region, then the image processing covers all areas, but unnecessary processing occurs reducing efficiency
Solution Approach 1:
The patent applies the extraction principle by isolating and focusing processing on only the necessary region within the forward-view image. By dynamically determining the ROI based on steering and braking information, the system extracts and processes only the relevant portion of the image that corresponds to the vehicle's actual driving context, eliminating unnecessary processing of irrelevant areas while maintaining comprehensive coverage of important regions.
