Multi-Camera Coordinate Association for Detection Setup
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional monitoring systems require significant effort to configure detection settings for each camera when monitoring a region using multiple cameras with different angles of view or zoom factors, necessitating individual setup for passage detection and intrusion detection.
Innovation Solution
An information processing apparatus that associates coordinates from one camera's video with those of another, allowing for the input and determination of position information for event detection across multiple cameras, thereby simplifying the configuration of detection settings by using an association unit, input unit, and determination unit.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional techniques are used to monitor a region using multiple cameras, then detection functions can be provided for each camera, but the effort to configure detection settings increases significantly for each individual camera
Solution Approach 1:
The patent applies the copying principle by automatically generating detection settings for the second camera based on the detection settings of the first camera. The coordinate association unit creates a mapping relationship between coordinates in videos from different cameras, allowing detection settings (such as detection lines for passage detection or closed regions for intrusion detection) to be copied and transformed from one camera to another, thereby eliminating manual configuration effort while maintaining detection functionality.
2Measurement precision
If detection settings are configured individually for each camera, then accurate event detection can be achieved, but the time required to set up monitoring increases
Solution Approach 1:
The patent applies preliminary action by pre-establishing coordinate association relationships between multiple cameras before actual event detection begins. The coordinate association unit creates a mapping between coordinates in videos from different cameras in advance, so that when detection settings are configured for one camera, the corresponding settings for other cameras can be automatically generated immediately, significantly reducing setup time while preserving detection accuracy.
3Adaptability or versatility
If multiple cameras with different angles of view and zoom factors are used, then comprehensive region monitoring is achieved, but the complexity of configuring detection settings for each camera increases
Solution Approach 1:
The patent applies universality by creating a unified coordinate association framework that works across multiple cameras with different angles of view and zoom factors. The coordinate association unit establishes a universal mapping relationship that can handle various camera configurations, allowing a single set of detection settings to be automatically transformed and applied to multiple cameras regardless of their individual parameters, thereby reducing configuration complexity while maintaining comprehensive monitoring coverage.

AI summary
An information processing apparatus comprising: an association unit configured to associate coordinates on a video captured by a first camera with coordinates on a video captured by a second camera based on specific positions specified in the video captured by the first camera and in the video captured by the second camera; an input unit configured to input position information for event detection by the first camera; and a determination unit configured to determine position information for event detection by the second camera based on the position information for the event detection by the first camera and on the association made by the association unit between the coordinates on the video captured by the first camera and the coordinates on the video captured by the second camera.
