Remote Work Machine Camera Selection for Clear Moving Views
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing work site monitoring systems using multiple cameras struggle to provide clear images of moving work machines, making it difficult for operators to manage and remotely operate these machines safely, as the machines appear small or are hard to track within the captured images.
Innovation Solution
A work assisting server that communicates with multiple imaging devices to select the optimal camera view based on the work machine's movement and content, ensuring the operator receives clear and relevant images without needing to manually switch cameras.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If multiple fixed point cameras are placed in work sites to overview the entire site, then the coverage area is improved, but the image quality and visibility of the work machine deteriorates (the work machine appears small or hardly appears)
Solution Approach 1:
The system dynamically switches between multiple fixed point cameras based on the work machine's position and movement. Instead of using a single static camera view, the system actively selects which camera to use in real-time, making the monitoring system adaptive to changing conditions. This resolves the contradiction by maintaining wide coverage through multiple cameras while ensuring high image quality by selecting the optimal camera for the current machine position.
Solution Approach 2:
The work machine itself provides information about its position and status, which the server uses to automatically determine the best camera view. The machine's own movement data and operational state are utilized to select the appropriate imaging device, eliminating the need for manual intervention and enabling automatic optimization of the view based on the machine's current needs.
2Measurement precision
If an operator manually switches between multiple imaging devices to track the work machine, then the image quality can be maintained, but the operation complexity and time consumption increases
Solution Approach 1:
The system performs automatic camera selection based on the work machine's position and movement data without requiring operator intervention. The server autonomously determines which camera provides the best view and switches between cameras automatically, eliminating the manual operation burden while maintaining high image quality throughout the tracking process.
Solution Approach 2:
The system continuously receives feedback about the work machine's position, movement state, and operational parameters, and uses this information to automatically adjust the camera selection. This closed-loop feedback mechanism ensures the optimal view is maintained without operator input, resolving the contradiction between image quality and operational simplicity.
3Stability of the object's composition
If fixed point cameras are used to monitor the work site, then the system stability is improved, but the ability to track moving work machines deteriorates (the machine motion changes every moment and is hard to track)
Solution Approach 1:
The system combines the stability of fixed point cameras with dynamic selection capability. While the cameras themselves remain stationary and stable, the system dynamically adapts by selecting different cameras based on the work machine's real-time position and movement, thereby maintaining both system stability and tracking adaptability.
Solution Approach 2:
Multiple fixed point cameras serve universal monitoring functions while collectively providing adaptive tracking capability. Each camera maintains its stable fixed position for general site overview, but together they enable dynamic tracking of the work machine through automated selection, making the system both stable and versatile.

AI summary
A work assisting server 10 includes a first assisting process element 121 and a second assisting process element 122 and communicates with a plurality of facility cameras 30 when an operator OP remotely operates a work machine 40 while viewing a captured image displayed on an image output device 221. The first assisting process element 121 extracts, as candidates, the facility cameras 30 including the work machine 40 in imaging ranges. The second assisting process element 122 selects the facility camera 30 that is able to obtain the imaging range including an optimal direction or size on the basis of movement of the work machine 40 and causes the selected facility camera 30 to output a captured image to the image output device 221.
