Surveillance Video Output System Using Movable Camera Selection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing surveillance systems using video data from cameras mounted on movable objects primarily focus on specific points, limiting the ability to display a wide range of areas, which is not suitable for users who need to monitor multiple locations simultaneously.
Innovation Solution
A system comprising multiple cameras on movable objects, with processors that select and output video data from cameras with the longest travel distance within a designated observation area, ensuring a wider range of coverage by combining video data from multiple cameras in chronological order.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If video data from cameras on movable objects is used for surveillance, then infrastructure costs are reduced, but the coverage area is limited to specific points only
Solution Approach 1:
The system combines video data from multiple movable cameras that pass through the same observation area at different times to create a composite surveillance video covering the entire area, merging limited individual views into comprehensive coverage
Solution Approach 2:
The system pre-processes and stores video data and position information from movable cameras before surveillance queries, enabling efficient retrieval and combination of relevant video segments when an observation area is designated
2Area of stationary object
If multiple cameras are used to expand coverage, then surveillance area increases, but system complexity increases
Solution Approach 1:
The system introduces a server as an intermediary that manages camera position data, video storage, and automatic selection/combination of camera footage, simplifying the complexity of coordinating multiple movable cameras while expanding coverage
3Area of stationary object
If cameras with longest travel distance are selected, then coverage within observation area is maximized, but selection complexity increases
Solution Approach 1:
The system changes the selection criterion from arbitrary or random camera selection to selecting cameras based on the parameter of travel distance within the observation area, automatically identifying cameras that moved the longest distance to maximize coverage

AI summary
A system for outputting a surveillance video, the system comprises a plurality of cameras each of which is mounted on a movable object, one or more memories storing, for each of the plurality of cameras, captured video data and time series position data, and one or more processors. The one or more processors execute selecting, for each predetermined time width, an observation camera which is one camera with the time series position data in which data within the predetermined time width are included in an observation area, and acquiring the captured video data within the predetermined time width of the observation camera. Then the one or more processors execute outputting the captured video data acquired for each of the predetermined time width in chronological order. Wherein the selecting the observation camera includes selecting one camera with the longest distance to travel in the observation area within the predetermined time width.
