Rotating Mirror Image Capture for Multi-Lane Biometric Clarity
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing image capturing systems for biometric identification in multiple lanes are costly and inefficient due to the need for separate optical equipment in each lane, leading to high initial and operational costs, and potential image blurring from rotating mirrors.
Innovation Solution
An image capturing apparatus with a rotating mirror that changes capturing directions to cover multiple lanes, capturing images after the rotating operation is completed to reduce unnecessary captures and shake, thereby reducing costs and improving image quality.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If separate optical equipment is installed in each lane for biometric identification, then image capturing reliability is improved, but device complexity and initial cost increase
Solution Approach 1:
A single image capturing apparatus is designed to serve multiple lanes by incorporating a rotating mirror that can redirect light paths to different lanes sequentially. The apparatus performs the same biometric identification function across multiple lanes without requiring separate equipment for each lane, thus reducing device complexity while maintaining reliability
Solution Approach 2:
The image capturing apparatus incorporates a rotating mirror that dynamically changes its angle to redirect light paths between different lanes. This dynamic adjustment allows a single static apparatus to capture images from multiple lanes at different time points, eliminating the need for multiple fixed apparatuses in each lane
2Device complexity
If a rotating mirror is used to capture images in multiple lanes, then device complexity is reduced, but image quality deteriorates due to camera shake and unnecessary captures
Solution Approach 1:
The control unit预先 determines which lanes require image capturing based on detection signals indicating target presence. The rotating mirror is then positioned to the appropriate angle before capturing, avoiding unnecessary captures in lanes without targets and preventing camera shake from continuous rotation
Solution Approach 2:
Instead of continuous rotation, the rotating mirror performs periodic angular movements to sequentially position itself at predetermined angles corresponding to different lanes only when needed. This periodic positioning reduces unnecessary motion and associated camera shake while still enabling multi-lane coverage
3Productivity
If continuous image capturing is performed in all lanes, then productivity is improved, but loss of energy and unnecessary captures increase
Solution Approach 1:
A detection signal generation unit provides feedback information about target presence in each lane to the control unit. The control unit uses this feedback to intelligently control the rotating mirror's angular position and timing, directing the image capturing apparatus only to lanes where targets are detected. This feedback mechanism maintains productivity by capturing images when needed while reducing energy loss by avoiding captures in empty lanes

AI summary
An image capturing apparatus according to the present disclosure includes: an image capturing unit that captures an image of a target; a rotating mirror that rotates about a first rotation shaft and is capable of changing an image capturing direction of the image capturing unit; and a control unit that controls the image capturing unit to capture an image of the target moving in a first direction in a first lane after causing the rotating mirror to rotate to a first angle and controls the image capturing unit to capture an image of the target moving in a second direction in a second lane after causing the rotating mirror to rotate to a second angle, the second direction being different from the first direction.
