Mobile Vehicle Imaging Unit Positioning for Blur Suppression
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional autonomous vehicles with cameras experience image blur due to vibrations, especially when turning, which complicates the image recognition process and increases costs with complex vibration absorption structures.
Innovation Solution
A mobile vehicle design featuring an electric undercarriage with independently rotating wheels and an imaging unit positioned in a circular region centered on the axle line between the wheels, allowing for reduced image blur without the need for vibration absorption members, and enabling the vehicle to turn with a smaller radius of curvature.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If a vibration absorption member is added to suppress image blur, then image quality improves, but device complexity and cost increase
Solution Approach 1:
The patent extracts the imaging unit from the vibrating body by mounting it on a separate, movable platform (the ball). This separates the camera system from the vibrations generated by the vehicle body, eliminating the need for vibration absorption members while maintaining image quality
Solution Approach 2:
The imaging unit is mounted on a movable platform (ball) that can dynamically adjust its position. This dynamic mounting system allows the imaging unit to move with the vehicle body while maintaining a stable imaging position, suppressing image blur without requiring complex vibration absorption mechanisms
2Area of stationary object
If the imaging unit is positioned far from the center of rotation, then imaging coverage improves, but image blur increases during turns
Solution Approach 1:
The imaging unit is mounted on a movable platform that can dynamically adjust its position relative to the vehicle body. This allows the imaging unit to be positioned for optimal coverage while compensating for vibrations and turns, maintaining both imaging coverage and image stability
