Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing imaging systems face challenges in efficiently adjusting optical positional relations between cameras and mirrors to effectively image targets at different focal lengths, limiting their ability to capture accurate images of varying subjects, such as faces and eyes, with a common mirror configuration.
Innovation Solution
An imaging system comprising a first camera with a first focal length, a second camera with a second focal length, and a first mirror, where a first adjustment unit adjusts the optical positional relation between the cameras and the mirror based on which camera is used to image the target, allowing each camera to perform imaging through the common mirror by adjusting the camera or mirror position.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a common mirror is used for both cameras with different focal lengths, then the system configuration is simplified, but the optical positional relation adjustment becomes complex and less efficient
Solution Approach 1:
The patent implements dynamic adjustment mechanisms that automatically modify the optical positional relations between cameras and mirrors based on which camera is actively imaging. The adjustment unit changes mirror angles and camera positions in real-time according to the active camera's focal length requirements, transforming a static complex configuration into a dynamically adaptive system that simplifies operation.
Solution Approach 2:
The system changes optical parameters (mirror angles, camera positions, focal lengths) according to the active camera configuration. When switching between cameras with different focal lengths, the adjustment unit modifies these parameters to optimize the optical path for each specific camera-mirror pairing, resolving the contradiction between using a common mirror and maintaining simple adjustment procedures.
2Device complexity
If the optical positional relation is fixed for a common mirror configuration, then the system structure is simplified, but the ability to image targets at different focal lengths accurately is limited
Solution Approach 1:
The system employs dynamic adjustment mechanisms that modify optical positional relations in real-time based on the active camera's focal length requirements. This allows the system to maintain simple fixed structure while achieving accurate imaging at different focal lengths through automated positional and angular adjustments of mirrors and cameras during operation.
