Around View Monitoring Camera Movement Correction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vehicle systems provide inaccurate around-view images due to camera movement with attached movable parts, such as side mirrors or doors, leading to blind spots and distorted views.
Innovation Solution
An apparatus comprising multiple cameras attached to both moving and fixed parts of a vehicle, with a processor that adjusts camera positions and composites images to correct for movement, highlighting blind spots and providing a clear around-view image.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If cameras are attached to moving parts of the vehicle body, then the system can capture images during vehicle operations such as door opening or mirror folding, but the around-view image becomes distorted and blind spots occur due to camera movement
Solution Approach 1:
The system performs preliminary actions by acquiring movement information of the moving part before or during image acquisition, and pre-calculates the composition region adjustment based on the detected movement direction and magnitude. This allows the processor to compensate for camera movement in advance, maintaining image accuracy while allowing cameras to be mounted on moving parts.
Solution Approach 2:
The system implements feedback by continuously monitoring the movement information of the moving part and using this information to dynamically adjust the composition region of the around-view image. The processor receives movement feedback, processes it to determine composition region adjustments, and applies corrections to maintain accurate spatial relationships in the final composite image.
2Reliability
If the composition region is adjusted based on moving part movement, then blind spots can be reduced, but the system complexity increases due to additional processing requirements
Solution Approach 1:
The processor performs multiple functions using a unified approach: it detects movement information, determines composition region adjustments, and composites images all within a single processing pipeline. This multi-functional design reduces overall system complexity by eliminating the need for separate dedicated modules for each function, while still achieving comprehensive blind spot reduction.
3Measurement precision
If cameras are fixed on the vehicle body, then the around-view image remains stable and undistorted, but the system cannot adapt to vehicle configurations during operation such as open doors or folded mirrors
Solution Approach 1:
The system applies dynamics by making the composition region adjustable and adaptable based on real-time movement information of moving parts. Instead of a fixed composition region, the system dynamically modifies the composition region parameters according to the detected movement, allowing the around-view image to adapt to changing vehicle configurations while maintaining stability through processed correction.
