3D Model Video Transmission for Remote Expert Guidance
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In process control systems, maintaining production continuity is crucial, but remote expert assistance often lacks contextual information, leading to inefficiencies and misinterpretations due to the limitations of traditional video transmission methods, which fail to provide a clear overview and detail simultaneously.
Innovation Solution
A video communication device that captures video images and creates a three-dimensional model of the location, determining the camera's orientation and transferring this model along with the video stream to the remote user, enhancing situational awareness by providing contextual data and allowing for better navigation and instruction.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If traditional video transmission methods are used to provide remote expert assistance, then the implementation is simple and costs are low, but the remote user lacks contextual information leading to misinterpretation and reduced effectiveness
Solution Approach 1:
The patent applies dimensionality change by transitioning from traditional 2D video transmission to 3D model-based spatial representation. The video communication device captures images from multiple cameras, processes them into a three-dimensional model of the location, and transmits this 3D model along with camera orientation data to the remote user. This allows the remote expert to view the industrial site from multiple angles and understand spatial relationships, significantly improving contextual information while maintaining manageable device complexity through automated processing.
2Measurement precision
If a camera zooms in to obtain details at the site, then detail visibility is improved, but it becomes hard to retain the overall view and context
Solution Approach 1:
The patent applies segmentation by dividing the visual information into multiple independent camera views that can be selectively displayed. Instead of relying on a single camera that must choose between zooming in or maintaining overview, the system uses multiple cameras positioned at different locations and angles. The remote user can switch between different camera perspectives or view them simultaneously, allowing detailed examination of specific areas while preserving awareness of the overall site context through other camera feeds.
3Loss of information
If multiple cameras are used to provide both overview and detail, then situational awareness is improved, but device complexity and cost increase
Solution Approach 1:
The patent applies merging by combining multiple camera feeds and processing them into a unified three-dimensional model representation. Rather than requiring the remote user to manually switch between multiple independent video streams, the system integrates the data from multiple cameras into a coherent 3D spatial model that automatically presents both overview and detail information in a single integrated view. This reduces the perceived complexity for the user while maintaining the benefits of multiple camera perspectives.
