Platooning Vehicle Object Identification via Cropped Video Sharing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing electronic devices in leading vehicles of platooning vehicles face high data processing burdens and potential delays or errors in identifying external objects, which can lead to accidents.
Innovation Solution
The electronic device in the leading vehicle transmits forward videos or cropped videos to other vehicles, utilizing information from both the leading and following vehicles to accurately identify external objects through distributed computing, reducing the data processing load on the leading vehicle.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the leading vehicle processes all video data alone, then identification accuracy may be maintained, but data processing burden increases and delays occur
Solution Approach 1:
The patent divides the video data processing task into segments: the leading vehicle captures forward video and crops regions of interest, while following vehicles process their respective video data. This segmentation distributes the computational burden across multiple vehicles, improving overall processing efficiency while maintaining identification accuracy through collaborative analysis of divided data portions.
2Loss of time
If the leading vehicle processes all video data alone, then centralized control is maintained, but processing time increases causing delays
Solution Approach 1:
The patent merges the processing capabilities of multiple vehicles into a unified external object identification system. The leading vehicle and following vehicles collectively process video data, combining their computational resources to reduce identification time. The system integrates data from multiple sources while maintaining coordinated control, effectively distributing complexity across the platoon rather than concentrating it in one vehicle.
3Productivity
If forward video is transmitted to following vehicles, then processing load on leading vehicle is reduced, but data transmission requirements increase
Solution Approach 1:
The patent extracts only the essential video data needed for external object identification and transmits it to following vehicles. Rather than transmitting complete high-resolution videos, the system extracts key regions or processed video segments that contain relevant information about external objects. This extraction approach reduces the volume of transmitted data while maintaining the sufficiency of information for accurate identification.

AI summary
An electronic device for platooning vehicles may obtain a forward video, generate cropped videos by cropping the forward video, transmit the forward video or at least one of the cropped videos to each of other electronic devices, obtain, from an external object included in the forward video or at least one of the cropped videos, first information related to the external object, receive, from the other electronic devices, second information related to the external object that is obtained from the external object included in the forward video or at least one of the cropped videos, and identify the external object, based on the first information and the second information.
