Worker Terminal Moving Image Processing for Remote Support
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The transmission of moving images using a worker terminal incurs significant communication costs, while maintaining image quality is essential for effective remote support at work sites.
Innovation Solution
A worker terminal equipped with a camera, an identifying unit for recognizing target areas, and a processing unit that adjusts the data amount per unit area for target and non-target areas during image transmission, allowing for reduced communication costs without compromising image quality.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the image quality is maintained at a high level for effective remote support, then the communication amount increases
Solution Approach 1:
The patent applies local quality by differentiating the data amount per unit area between target areas and non-target areas. The processing unit identifies target areas containing work site information and transmits them with higher data amounts to maintain image quality, while transmitting non-target areas with lower data amounts to reduce communication costs. This selective quality adjustment resolves the contradiction between maintaining overall image quality and reducing total communication amount.
2Quantity of substance
If the data amount per unit area is reduced to decrease communication costs, then the image quality deteriorates
Solution Approach 1:
The patent prevents image quality deterioration by applying different data amounts per unit area to different regions. Target areas containing critical work site information are transmitted with sufficient data amounts to maintain quality, while non-critical areas use reduced data amounts. This localized approach ensures that image quality is maintained where needed without sacrificing communication efficiency.
Solution Approach 2:
The patent segments the moving image into target areas and non-target areas based on recognition results. By dividing the image content and applying different transmission quality levels to each segment, the system maintains overall image quality for remote support while reducing total communication amount through selective compression of non-critical regions.

AI summary
The communication amount is reduced while maintaining image quality when transmitting moving images by using a worker terminal. A worker terminal is configured to be connected to a support apparatus and transmit a moving image to the support apparatus upon encoding the moving image, the support apparatus being configured to support, from a remote location, work performed by a worker including installing, repairing, inspecting, or removing a device, based on the moving image captured at a work site, the worker terminal including a camera configured to capture the moving image; an identifying unit configured to perform a recognition process on the moving image captured by the camera to identify a target area; and a processing unit configured to process the moving image such that a data amount per unit area at a time of transmitting the moving image is different for the target area and a non-target area other than the target area, in response to detecting that the target area is identified in the moving image.
