Vehicle Camera Image Merging for Redundant Data Reduction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vehicle systems transmit redundant and overlapping image data from multiple cameras, increasing bandwidth usage without providing additional information for vehicle functions like speed estimation or camera calibration.
Innovation Solution
A method that automatically merges image recordings from multiple vehicle cameras, selecting only regions of interest and removing redundant or overlapping areas before transmission to the central control device, thereby reducing data volume.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If image recordings from multiple cameras are transmitted without merging, then complete spatial coverage is maintained, but data transmission bandwidth increases due to redundant overlapping regions
Solution Approach 1:
The patent merges multiple image recordings from different cameras by identifying and combining overlapping regions, keeping only one copy of redundant data. This reduces the total data volume transmitted while preserving all unique spatial information from the multiple cameras.
Solution Approach 2:
The system extracts and removes redundant overlapping regions from the image recordings before transmission. By identifying regions that appear in multiple camera views and removing duplicates, the data volume is reduced while maintaining complete spatial coverage.
2Productivity
If all image data from multiple cameras is processed centrally, then comprehensive image processing is achieved, but processing effort and computational load increase
Solution Approach 1:
The patent performs preliminary merging of image recordings at the camera or edge device level before central transmission. By pre-processing and combining images upstream, the computational load at the central controller is reduced while ensuring that only necessary unique data is processed for vehicle functions.
Solution Approach 2:
The system segments the image processing task into two parts: merging operations performed at the data source (cameras or edge devices), and vehicle function processing performed centrally. This segmentation distributes computational effort and reduces the burden on the central processing unit.
3Quantity of substance
If redundant image regions are removed before transmission, then bandwidth usage is reduced, but device complexity increases due to merging operations
Solution Approach 1:
The patent introduces an intermediary merging module that operates between the cameras and the central controller. This intermediary performs the complex merging operations locally, reducing the data burden on the central system while isolating the complexity to a dedicated component rather than the entire system.

AI summary
A method for provision image recordings in a vehicle. The method include: ascertaining a first image recording of a first image sensor of the vehicle and at least one further image recording of at least one further image sensor of the vehicle; carrying out a merging of the first image recording and the at least one further image recording for a reduction of an amount of data for providing the relevant information, the merging taking place based on a selection from the surrounding regions, whereby at least one merged image recording is obtained; initiating at least one transmission of the merged image recording within the vehicle and at least to a central control device of the vehicle, whereby the merged image recording is supplied to a processing for performing the vehicle function.
