Multi-Camera Position Management Using Shared Address Regions
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing systems struggle to stably manage the position of an object based on code images captured by multiple cameras with overlapping capturing regions, leading to inconsistent identification of object positions.
Innovation Solution
An information processing system that assigns unique address identification information to non-overlapping regions of camera views, allowing stable management of object positions by recognizing color code images across multiple cameras.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If multiple cameras are used to capture code images of the entire management area, then the coverage area is improved, but the position management stability deteriorates due to overlapping capturing regions causing inconsistent object position identification
Solution Approach 1:
The management area is segmented into multiple non-overlapping regions, each assigned to a specific camera. This segmentation eliminates the overlapping capturing regions that cause inconsistent position identification, while still ensuring complete coverage of the entire management area through coordinated monitoring by multiple cameras.
2Reliability
If cameras are positioned to capture overlapping regions, then the reliability of code image recognition is improved, but the position management accuracy deteriorates due to ambiguous object location identification
Solution Approach 1:
Each camera is assigned to monitor a specific non-overlapping region with unique address identification information. This local quality assignment ensures that code images are reliably recognized within each camera's designated region while maintaining precise object position identification, as each position has a unique camera-region association.

AI summary
An information processing system (12) includes image capturing devices (18) disposed to capture images of a management area; an information processing apparatus (14) to recognize a code image corresponding to an object in the management area, from a captured image captured by the image capturing devices, and manage a location of the object; an address setting unit (32) to set address identification information associated with position information in the management area to a region of the captured image; and a management unit (36) to, based on recognition of the code image in the region, manage the position information associated with the address identification information set for the region, as a location of the object corresponding to the code image. The address setting unit commonly sets one piece of the address identification information associated with the position information, for regions of different captured images captured by the image capturing devices.
