Mobile Robot Camera Resolution Control for Transmission Rate
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing robot control systems experience image distortion and data loss during live-view moving picture transmission from a mobile robot to a remote control center due to sudden changes in data transmission rates, limiting smooth user control of the mobile robot.
Innovation Solution
The system adjusts the resolution of next images to be transmitted based on the current data transmission rate, with the resolution being inversely proportional to the transmission rate, and prioritizes channels based on importance degrees to prevent data loss and distortion.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If the resolution of transmitted images is maintained at a high level, then the image quality is improved, but the data transmission rate increases causing data loss and distortion
Solution Approach 1:
The system dynamically adjusts the image resolution based on real-time transmission rate conditions. When transmission rate decreases, the resolution is lowered to prevent data loss; when transmission rate increases, the resolution is raised to improve image quality. This dynamic adaptation resolves the contradiction between maintaining high image quality and preventing data loss under varying transmission conditions.
Solution Approach 2:
The system changes the resolution parameter of transmitted images according to the transmission rate. By adjusting this key parameter based on channel conditions, the system optimizes the balance between image quality and data transmission reliability, preventing both data loss and distortion.
2Manufacturing precision
If the resolution of transmitted images is maintained at a high level, then the image quality is improved, but the transmission reliability deteriorates due to limited transmission capacity
Solution Approach 1:
The system dynamically adapts the image resolution to match transmission capacity conditions. When transmission capacity is limited, resolution is reduced to ensure reliable transmission; when capacity increases, resolution is increased to improve quality. This dynamic adjustment resolves the contradiction between image quality and transmission reliability.
Solution Approach 2:
The system modifies the resolution parameter based on transmission rate feedback, optimizing the trade-off between image quality and transmission reliability under varying channel conditions.
3Productivity
If the transmission rate suddenly increases, then more data can be transmitted, but data loss occurs due to limitations in transmission capacity
Solution Approach 1:
The system uses feedback from the transmission rate to adjust the image resolution. When transmission rate suddenly increases, the system responds by adjusting resolution to match the actual transmission capacity, preventing data loss while utilizing available bandwidth effectively.
Solution Approach 2:
The system changes the resolution parameter in response to transmission rate variations, optimizing data transmission to prevent loss while maximizing utilization of available transmission capacity.
