Rearview Camera Stitching Correction After Folding Wing Misalignment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Rearview systems with multiple cameras often experience stitching problems due to misalignment caused by folding camera wings, leading to visible interruptions or offsets in the displayed image, which can compromise driver safety and require costly manual calibration by technicians.
Innovation Solution
A method allowing drivers to manually correct stitching issues using a user-friendly interface on a touch-sensitive display, with orientation lines and intuitive controls to align camera images without needing special equipment or expertise, ensuring accurate composite image stitching.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If camera wings are folded for maneuvering, then the vehicle can pass through narrow spaces, but stitching accuracy deteriorates causing visible interruptions in the composite image
Solution Approach 1:
The system performs preliminary detection of folding events and automatically triggers calibration mode when the camera wing returns to operating position, preparing the correction before the driver notices the stitching problem
Solution Approach 2:
The system enables drivers to perform calibration themselves through an automated assistant that guides them through the process using familiar reference objects (curbs, road markings), eliminating the need for professional technicians and special calibration equipment
2Manufacturing precision
If manual calibration by technicians is performed, then stitching accuracy is restored, but time loss and cost increase
Solution Approach 1:
The system empowers drivers to perform calibration themselves through an automated assistant that provides step-by-step guidance using everyday reference objects, completely eliminating the need for technician intervention and reducing calibration time from hours to minutes
Solution Approach 2:
The system changes the calibration approach from using specialized calibration targets and equipment to using familiar environmental reference objects (curbs, road markings, building edges), making the process accessible to drivers without technical expertise
3Area of stationary object
If multiple cameras are provided for comprehensive rearview, then coverage area increases, but system complexity and stitching difficulty increase
Solution Approach 1:
The system automatically detects when stitching problems occur and guides drivers through calibration using familiar reference objects, eliminating the need for complex automated calibration equipment and reducing system complexity while maintaining multi-camera coverage

AI summary
The disclosure refers to a method for correcting stitching problems in a rearview system, said rearview system comprising at least two cameras mounted on at least one external camera wing of a vehicle, with the at least one camera wing being configured to be moved between an operating position, in which each camera has a rearview for capturing an image, and at least one folding position, and at least one display configured for displaying at least one of the images captured by each of the at least two cameras as a composite image and a menu for correcting stitching problems, the method comprising the steps of determining a change from the at least one folding position to the operating position of the at least one camera wing; opening the menu for correcting stitching problems; and closing the menu either after correction or after receiving a signal to skip correction.
