AVM Side-View Fail-Safe Image Rotation and Distortion Correction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vehicle side monitoring systems fail to provide a continuous and stable side image to the driver when abnormalities occur in the components, limiting the field of view and requiring additional fail-safe components that occupy valuable space.
Innovation Solution
A vehicle side monitoring system with a fail-safe function that includes imaging device controllers connected to side-view imaging devices and an Around View Monitoring (AVM) system, where a controller determines abnormalities and displays corrected, rotation-transformed images from the AVM imaging device on side-view monitors, ensuring continuous image provision without additional components.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a separate side-view mirror part is provided as a fail-safe component when an abnormality occurs in the side and rear monitoring system, then the system reliability is improved, but the device complexity increases and space is occupied
Solution Approach 1:
The patent merges the fail-safe function with the existing side-view monitor by enabling it to display images from both the side-view camera and the AVM imaging device. Instead of adding a separate physical side-view mirror, the system combines multiple image sources into a single display unit, maintaining reliability while avoiding additional components and space occupation.
Solution Approach 2:
The side-view monitor is designed to perform multiple functions: it displays images from the side-view camera during normal operation and switches to displaying images from the AVM imaging device when an abnormality is detected. This multi-functionality eliminates the need for dedicated fail-safe components while maintaining system reliability.
2Reliability
If a separate side-view mirror part is provided as a fail-safe component, then the system reliability is improved, but the area occupied within the vehicle increases
Solution Approach 1:
The patent merges the fail-safe function with the existing side-view monitor by enabling it to display images from both the side-view camera and the AVM imaging device. Instead of adding a separate physical side-view mirror, the system combines multiple image sources into a single display unit, maintaining reliability while avoiding additional components and space occupation.
3Measurement precision
If image distortion correction and rotation transformation are performed, then the image quality and viewing angle are improved, but the processing time and computational load increase
Solution Approach 1:
The patent performs image distortion correction and rotation transformation in advance during the image processing stage, before the images are displayed. By pre-processing the images from the AVM imaging device, the system prepares corrected and properly oriented images ready for immediate display, reducing real-time processing delays when fail-safe mode is activated.

AI summary
A vehicle side and rear monitoring system with a fail-safe function and a method thereof are provided. The system provides a fail-safe function for safe driving of a vehicle when an abnormality occurs in a side monitoring system of the vehicle, and a technique that provides a continuous side field of view of the vehicle when an abnormality occurs in the side monitoring system in the vehicle equipped with an AVM system. In addition, the system and provides a technique that corrects the distortion of an image captured by an AVM camera and performs an image rotation transformation to provide the image captured by the AVM camera at the same angle as that provided by side-view cameras. Therefore, when an abnormality occurs in the side monitoring system, the vehicle side and rear monitoring system with a fail-safe function continuously provides the same image as captured by the side-view cameras.
