Virtual Camera Synchronization for Remote Supervision in Video-Prohibited Zones
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing techniques for remote management of workers at sites where video output is prohibited do not allow remote managers to confirm the area being viewed by workers, hindering effective instruction and supervision.
Innovation Solution
An information processing method that constructs a 3D model of a target object in a virtual space, synchronizes the position and orientation of a virtual camera with the worker's in real space, and generates a virtual camera video to display the worker's field of view, enabling remote managers to confirm the area without actual video output.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If a video at the work site is output to allow remote managers to confirm the worker's field of view, then the remote manager can confirm the place looked at by the worker, but video output is prohibited at the work site
Solution Approach 1:
The patent creates a virtual copy of the work site by constructing a 3D model of the target object in virtual space. Instead of outputting actual video from the work site, the system generates a virtual camera video that copies the worker's field of view by synchronizing the virtual camera's position and orientation with the worker's head-mounted device. This allows remote managers to view the work area through the virtual copy without violating the no-video-output restriction at the actual site.
2Loss of information
If a 3D model and virtual camera system is constructed to enable remote viewing, then remote managers can confirm the worker's field of view without actual video output, but the system complexity increases
Solution Approach 1:
The patent introduces a virtual camera as an intermediary between the worker's head-mounted device and the remote manager's display. The virtual camera captures the 3D model from the worker's perspective and transmits this virtual video feed to the remote manager. This intermediary approach allows field of view information to be transmitted without directly outputting video from the work site, resolving the contradiction between information loss prevention and video output prohibition.
Solution Approach 2:
The patent transitions from 2D video output to a 3D virtual space representation. By constructing a three-dimensional model of the target object and positioning a virtual camera within this 3D space, the system provides spatial awareness and depth information that flat video cannot convey. This dimensional enhancement allows remote managers to better understand the worker's field of view and spatial context.

AI summary
An information processing device constructs, in a virtual space, a three-dimensional (3D) model of a target object to be worked on by a worker in a real space, acquires position information and orientation information of the worker in the real space, synchronizes a position and an orientation of a virtual camera in the virtual space with a position and an orientation of the worker based on the position information and the orientation information, generates a virtual camera video which shows the 3D model captured by the synchronized virtual camera, and outputs output information for displaying an output image that includes the virtual camera video.
