Drive Recorder Playback With Bird's-Eye View for Close-Cut Verification
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
It is difficult to determine the degree of road rage and verify dangerous driving by another vehicle when a video captured by a drive recorder is reproduced, especially in events involving close proximity while traveling at high speeds.
Innovation Solution
A recording and reproducing control device that acquires video data from a vehicle-mounted camera, detects close proximity of another vehicle, performs point-of-view conversion to create a bird's-eye view, and records and reproduces the video data to display the relative positional relationship between vehicles, facilitating easier determination of road rage incidents.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If normal drive recorder video is reproduced, then the video data is recorded and played back, but it is difficult to determine the degree of road rage and verify dangerous driving by another vehicle
Solution Approach 1:
The patent applies point-of-view conversion to transform the video data from the camera's original perspective to a bird's-eye view perspective. This dimensional transformation allows observers to see the relative positional relationships between vehicles from an overhead perspective, making it easy to determine the degree of road rage and verify dangerous driving behaviors such as tailgating or cutting in.
2Measurement precision
If point-of-view conversion is performed on all video data, then the relative positional relationship is clearly shown, but the processing time and computational load increase
Solution Approach 1:
The patent performs point-of-view conversion in advance during the video recording phase, storing the converted bird's-eye view video data alongside the original video data. This preliminary action ensures that when verification is needed, the converted video is already available for immediate playback without requiring real-time processing, thus avoiding time loss during critical verification moments.
3Ease of operation
If video data is processed to show relative positional relationships, then road rage verification is easier, but the device complexity increases
Solution Approach 1:
The patent introduces a point-of-view conversion processor as an intermediary component that bridges the gap between the original video data and the verification process. This dedicated processing unit handles the complex coordinate transformations and perspective conversions, isolating the complexity from the main control system and providing a clear interface for verification through bird's-eye view display.

AI summary
A recording and reproducing control device includes a video data acquisition unit configured to acquire video data imaged by an imager for at least one of a front view and a rear view of a vehicle; a detector configured to detect that another vehicle gets close in a distance smaller than a predetermined distance to the vehicle while the vehicle is traveling at a predetermined speed or higher; a point-of-view conversion processor configured to perform a point-of-view conversion process for a bird's-eye view on the acquired video data; a recording controller configured to record the acquired video data; a reproduction controller configured to, when reproducing the video data of a period during which the another vehicle getting close in the predetermined distance or smaller to the vehicle is detected, reproduce the converted video data; and a display controller configured to cause a display to display the reproduced video data.
