Multi-Camera Face Authentication Layout for User Height Adaptation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing information processing systems face challenges in capturing high-quality images of individuals from various angles and heights, particularly for face authentication, while ensuring privacy and efficient data input/output operations.
Innovation Solution
The system employs multiple cameras positioned around a display unit - left, right, and upper - to capture images from different angles, along with a monitoring camera for situational awareness, and a reception unit for non-contact input, combined with a mechanism to adjust the display and reading unit based on user height for optimal image capture and operation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If multiple cameras are positioned around the display unit to capture images from different angles, then the quality and suitability of captured face images for authentication is improved, but the device complexity increases
Solution Approach 1:
The camera system is segmented into multiple independent camera units (left camera, right camera, upper camera, monitoring camera) positioned at different locations around the display unit. Each camera captures images from its specific angle, and the control unit selectively uses images from appropriate cameras based on the user's position and requirements, thereby achieving high-quality multi-angle capture while managing system complexity through modular design
Solution Approach 2:
The multiple cameras serve universal purposes for both authentication and monitoring functions. The same camera system captures images for face authentication verification while simultaneously providing situational awareness through the monitoring camera, allowing one system to perform multiple functions and justify the added complexity
2Adaptability or versatility
If a monitoring camera is added to monitor the target from the upper side, then situational awareness is improved, but the device complexity increases
Solution Approach 1:
The monitoring camera integrated into the upper camera unit serves dual purposes: it provides situational awareness by capturing images from the upper side to monitor the target's surroundings, while also contributing to the authentication process by capturing additional perspective data. This multi-functionality justifies the added complexity by enabling one component to serve multiple critical functions
3Ease of operation
If the display and reading unit are adjusted based on user height, then user comfort and operation efficiency are improved, but the device complexity increases
Solution Approach 1:
The display unit and reading unit are designed with adjustable positioning capabilities that can dynamically adapt to different user heights. The control unit receives user height information and automatically adjusts the display and reading unit positions to optimal locations for each user, thereby improving comfort and operation efficiency while managing complexity through automated dynamic adjustment rather than manual intervention
4Object-affected harmful factors
If multiple cameras are used to capture images from various angles, then the ability to block external views and ensure privacy is improved, but the device complexity increases
Solution Approach 1:
The cameras are positioned asymmetrically around the display unit at different heights and angles (left, right, upper positions) rather than in symmetric arrangements. This asymmetric positioning creates overlapping fields of view that effectively block external views of sensitive areas while capturing comprehensive images for authentication, thereby enhancing privacy protection through strategic non-symmetric camera placement
