Camera Cleaning Control Synchronized With Exposure Cycles
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing camera cleaning control methods disrupt image acquisition in vehicle cameras, affecting driving experience and safety, especially in automatic driving scenarios.
Innovation Solution
A camera cleaning control method that determines a target camera for cleaning, identifies a cleaning period synchronized with the camera's exposure and acquisition cycles, and performs cleaning during this period to avoid interfering with image acquisition.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If camera cleaning is performed immediately when needed, then cleaning effectiveness is improved, but image acquisition is disrupted
Solution Approach 1:
The cleaning operation is performed periodically at specific intervals within the camera's operational cycle, specifically during the blanking period between frame exposures. This periodic timing ensures that cleaning occurs only when the camera is not actively capturing images, thus maintaining both cleaning effectiveness and image acquisition quality.
Solution Approach 2:
The cleaning operation is scheduled in advance during the blanking period before the next frame acquisition begins. By performing cleaning preliminarily within the available time window, the system ensures that the lens is clean for the subsequent image capture without disrupting the imaging process.
2Reliability
If multiple lenses are switched during cleaning, then cleaning coverage is improved, but system complexity increases
Solution Approach 1:
The cleaning process is segmented into discrete steps corresponding to each lens position. The system switches to a specific lens, performs cleaning for that lens, then switches to the next lens. This segmentation allows thorough cleaning of multiple lenses while maintaining a simple, systematic approach that doesn't significantly increase overall system complexity.
Solution Approach 2:
The lens switching and cleaning process follows a periodic pattern where each lens is sequentially activated and cleaned during designated time intervals. This periodic operation ensures comprehensive cleaning coverage while using a straightforward cyclic mechanism rather than a complex simultaneous multi-lens cleaning system.
