PTZ Camera Control via Wide-Area Specification Screen
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current monitoring camera systems face limitations in simultaneously capturing wide areas while maintaining image resolution, as existing PTZ cameras are restricted to imaging within the field of view of a wide-area camera, making it difficult to intuitively adjust the image-capturing area to a target region, especially when objects span across the boundary of the wide-area camera's field.
Innovation Solution
An image-capturing system comprising a wide-area camera and a PTZ camera, where a specification screen allows users to select an image-capturing area outside the wide-area camera's field, enabling the PTZ camera to adjust its image-capturing direction and viewing angle to capture the specified area, with motors controlled by a system control unit to achieve precise imaging.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If a PTZ camera is used to precisely image a specific area, then the image resolution is improved, but the device complexity increases due to additional motors and control mechanisms
Solution Approach 1:
The monitoring system is divided into two independent image-capturing units: a wide-area camera for broad coverage and a PTZ camera for detailed imaging. Each unit operates autonomously with its own control mechanisms, allowing the system to achieve both wide-area monitoring and precise imaging without requiring a single complex device to perform all functions.
Solution Approach 2:
The system combines multiple functions (wide-area monitoring and precise imaging) into a unified monitoring system that can perform both tasks using coordinated operation of the wide-area camera and PTZ camera, rather than requiring separate independent systems.
2Device complexity
If the PTZ camera is restricted to imaging within the wide-area camera's field of view, then the device complexity is reduced, but the adaptability decreases when objects span across the boundary
Solution Approach 1:
The imaging coverage is segmented into two distinct fields: the wide-area camera covers a broad region, while the PTZ camera covers a narrower region that can be positioned independently. This segmentation allows the PTZ camera to image areas outside the wide-area camera's field of view when needed, enhancing adaptability without increasing the complexity of individual devices.
Solution Approach 2:
The system adds a dimensional flexibility by allowing the PTZ camera to operate independently in terms of field of view coverage. The PTZ camera can be directed to capture areas beyond the wide-area camera's boundaries, creating a two-dimensional coverage strategy where the combination of both cameras provides comprehensive monitoring capability.
3Device complexity
If a single monitoring camera is used to satisfy both wide-area and precise monitoring requirements, then the device complexity is reduced, but the manufacturing precision and performance limitations occur
Solution Approach 1:
The monitoring function is segmented into two specialized devices: a wide-area camera optimized for broad coverage and a PTZ camera optimized for precise imaging. Each device can be manufactured and optimized for its specific function, with the PTZ camera achieving high image resolution through its dedicated optical and sensor system without compromising wide-area coverage capability.
Solution Approach 2:
Different parts of the monitoring system have different quality characteristics optimized for their specific functions. The wide-area camera is optimized for coverage area, while the PTZ camera is optimized for image resolution and detail. This local quality optimization allows each device to perform its function at peak performance without compromising the other.
