Dual Camera Tracking System for Wide-Area Monitoring
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional multi-camera systems are limited in extensibility, require high installation costs, and struggle to capture high-definition images of moving objects across a wide area due to the need for multiple cameras and cumbersome operation.
Innovation Solution
An information processing system that includes region image pickup, detection, designation, and setting means to switch between cyclic image pickup and continuous tracking modes, allowing for efficient capture of images of moving objects within a predetermined region.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If multiple cameras are used to monitor a wide area and capture high-definition images of moving objects, then the image quality and coverage area are improved, but the installation cost and system complexity increase
Solution Approach 1:
The system divides the wide-area monitoring function into two segments: a first camera captures the entire wide area at low definition, while a second camera captures high-definition images of specific moving objects. This segmentation allows the system to achieve both wide coverage and high image quality without requiring multiple high-definition cameras, thereby reducing system complexity and cost.
2Area of stationary object
If multiple cameras are deployed to cover a wide area, then the coverage area is improved, but the installation cost increases
Solution Approach 1:
The system uses a first camera to capture the entire wide area and a second camera to capture specific moving objects. By dividing the monitoring functions, the system achieves wide coverage without requiring multiple expensive high-definition cameras, thereby reducing installation cost while maintaining extensive coverage area.
3Measurement precision
If the number of cameras is increased to capture high-definition images across the entire region, then the image definition is improved, but the operation becomes more cumbersome
Solution Approach 1:
The system employs automatic object detection and tracking functionality that operates without manual intervention. The detection unit automatically identifies moving objects in the wide-area image, and the control unit automatically switches the second camera to track and capture high-definition images of these objects. This automation eliminates the need for manual operation, making the system easy to use while maintaining high image definition.
4Ease of manufacture
If a single camera is used to monitor a wide area, then the system cost is reduced, but the ability to capture high-definition images of moving objects is compromised
Solution Approach 1:
The system divides the image capture function between two cameras: the first camera captures the wide area at lower definition to maintain cost-effectiveness, while the second camera is dedicated to capturing high-definition images of moving objects. This segmentation allows the system to achieve both cost reduction and high image definition for moving objects simultaneously.
Solution Approach 2:
The second camera serves multiple functions: it can capture high-definition images of moving objects when needed, and the system can switch between different capture modes based on requirements. This multi-functionality allows a single camera to handle both wide-area monitoring and high-definition object capture, reducing the total number of cameras needed while maintaining image quality.

AI summary
A information processing apparatus and method is disclosed wherein an image of a predetermined region can be picked up and a desired moving body in the predetermined region can be tracked readily to pick up an image of the moving body. A sensor image acquisition module acquires a sensor image. A moving body detection module detects moving bodies existing in a predetermined region based on the sensor image. A tracking object designation module designates one of the detected moving bodies. When a moving body is designated by the tracking object designation module, an image pickup mode changeover module sets the image pickup mode to a continuous tracking mode in which the designated moving body is tracked to pick up an image of the moving body. The invention can be applied, for example, to a monitoring system.
