Variable Orientation Camera System for Vehicle Road Course Capture
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing camera systems for vehicles fail to continuously capture the road course in front of the vehicle with good resolution, particularly during cornering, due to limited field of view and inability to pre-adjust the camera orientation before a turn.
Innovation Solution
A variable-orientation camera system with a control unit that utilizes driving-related parameters and satellite-based information to pre-adjust the camera orientation before cornering, allowing it to swivel into the correct direction, and adjust capturing range and vertical orientation as needed, ensuring continuous and high-resolution road course capture.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If the camera uses a fixed orientation during cornering, then the camera structure remains simple, but the road course cannot be continuously captured with good resolution
Solution Approach 1:
The control unit pre-adjusts the camera orientation before the vehicle enters a curve based on navigation data about the upcoming road geometry. This preliminary action ensures the camera is already positioned to capture the road course at the correct angle when cornering begins, maintaining high resolution without requiring complex real-time adjustment mechanisms during the turn
2Productivity
If the camera adjusts orientation during cornering, then continuous road course capture is improved, but the response time to adapt to changing driving conditions deteriorates
Solution Approach 1:
The system uses navigation data to predict upcoming curves and pre-positions the camera in the correct orientation before the vehicle enters the turn. This eliminates the need for time-critical adjustments during cornering, as the camera is already optimized for capturing the road course throughout the maneuver
Solution Approach 2:
The control unit continuously receives feedback from the navigation system about the vehicle's position and upcoming road geometry, allowing it to proactively adjust camera orientation in response to changing driving conditions without delay
Data Source
AI summary
The invention relates to a camera system for vehicles comprising a camera with variable orientation for capturing the course of the road in front of a vehicle. The control of the camera by a controller is disclosed, which guarantees a good spatial resolution when travelling around corners as well as when travelling straight ahead. The controller receives vehicle dynamic travel parameters or satellite information on the current location of the vehicle, the course and/or geographical position of the road.
