Mobile Robot Video Segmentation for Privacy and Security
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional monitoring systems fail to balance security and privacy, as they often inadvertently capture sensitive areas, compromising user privacy when a mobile robot is dispatched to investigate abnormalities.
Innovation Solution
A monitoring system that includes a mobile robot with a camera capable of autonomous and remote control modes, a monitoring terminal for displaying videos, and a system control apparatus that distinguishes between security and privacy priority areas, allowing unprocessed video display in security areas while inhibiting it in privacy areas to protect user privacy.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a mobile robot with camera is dispatched to investigate abnormalities detected by monitoring sensors, then security monitoring capability is improved, but user privacy in sensitive areas is compromised
Solution Approach 1:
The monitoring area is divided into security priority areas and privacy priority areas with different monitoring requirements. The system applies different video processing strategies to different spatial zones: unprocessed video is displayed for security areas while processed video is displayed for privacy areas, allowing the mobile robot to monitor all areas without uniformly compromising privacy.
2Productivity
If unprocessed video is displayed on monitoring terminal for real-time security assessment, then security response efficiency is improved, but privacy protection is weakened
Solution Approach 1:
The video stream is segmented based on spatial location information. The system separates the monitoring area into security priority areas and privacy priority areas, then processes and displays video segments differently: security areas are displayed in unprocessed form for immediate assessment, while privacy areas undergo processing to protect user information.
Solution Approach 2:
The video processing parameter changes dynamically based on the robot's location and the monitored area's classification. When the robot is in or monitoring privacy priority areas, video processing is applied; when in security priority areas, unprocessed video is transmitted. This parameter change allows real-time adaptation between security and privacy requirements.
3Speed
If the mobile robot operates in autonomous movement mode to rapidly respond to alarms, then response speed is improved, but control flexibility is reduced
Solution Approach 1:
The mobile robot's control mode is made dynamic, allowing switching between autonomous movement mode and remote control mode based on situational requirements. The system can rapidly deploy the robot in autonomous mode for speed, then transition to remote control mode when human judgment and flexibility are needed, combining the advantages of both approaches.

AI summary
A monitoring system includes: a monitoring sensor; a mobile robot configured to switch between an autonomous movement mode and a remote control mode; a monitoring terminal; and a system control apparatus configured to switch between the autonomous movement mode and the remote control mode of the mobile robot based on an alarm activation and to determine a manner of a video to be displayed on a display device. In response to a detection of the alarm activation of the monitoring sensor, the system control apparatus permits the display device to display a video in the security priority area in an unprocessed manner and inhibits the display device from displaying a video in the privacy priority area in the unprocessed manner.
