Dynamic Video Pattern Switching for Multi-Camera Driver Assistance
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing video processing systems for driver assistance struggle to dynamically switch synthesized video patterns in response to changing driving situations, as they are limited to a single predefined pattern when using multiple cameras.
Innovation Solution
A video processing apparatus that includes multiple capturing units, video inputting units, a pattern information storing unit, a process unit, and a video outputting unit, allowing for the selection and generation of different video patterns by clipping and combining video data from multiple cameras, and coordinate-converting it for stereoscopic display.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a single predefined video pattern is used for driver assistance, then the system structure is simple, but the system cannot adapt to different driving situations
Solution Approach 1:
The video processing system implements dynamic pattern switching by allowing the video pattern to change based on driving situations. The system stores multiple video patterns and selects appropriate patterns dynamically according to the current driving context, making the system adaptable without requiring a completely new design for each situation.
Solution Approach 2:
The video processing apparatus is designed with multi-functionality by incorporating multiple capturing units that can capture videos from different positions and angles. These multiple video inputs are processed to generate various synthesized video patterns, allowing a single system to serve multiple driving assistance functions.
2Area of stationary object
If multiple cameras are used to capture videos from different positions, then the coverage area increases, but the video processing complexity increases
Solution Approach 1:
The system merges videos captured from multiple camera positions by synthesizing them into a single comprehensive video pattern. The video processing unit combines the multiple video inputs according to stored pattern information, creating a unified synthesized video that presents a complete view of the surrounding area while managing processing complexity through systematic combination methods.
3Speed
If synthesized video patterns are generated in real-time, then the responsiveness to driving situations improves, but the processing time increases
Solution Approach 1:
The system performs preliminary actions by storing video pattern information in advance before actual video synthesis is needed. The pattern information, including clipping ranges and combination methods, is pre-configured and stored in the video processing unit, allowing rapid pattern switching without extensive real-time computation when driving situations change.
