Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In remote-operated vehicle systems, inadequate representations of a vehicle's surroundings can occur due to high image-to-image latency, incorrect transmission, or erroneous rendering of sensory data, posing safety and security risks, and existing solutions are complex and costly without adequately addressing these issues.
Innovation Solution
A method and system where an encoded pattern representing predetermined information is embedded in image frames captured by a vehicle's sensors, transmitted to a remote terminal, and decoded to verify the accuracy of the sensory data, allowing for safer operation by detecting errors in transmission or rendering and ensuring the representation is adequate for vehicle control.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If communication systems with sufficient speed and redundancy are implemented, then the reliability of sensory data transmission is improved, but the device complexity and cost increase significantly
Solution Approach 1:
A light emitting device serves as an intermediary component that visually encodes predetermined information (such as timestamps or data integrity indicators) directly onto the image frames captured by the imaging device. This intermediary encoding mechanism provides a simple, low-cost verification method that does not require complex communication protocols or redundant transmission systems, thereby improving reliability while maintaining simplicity.
2Reliability
If communication systems with sufficient speed and redundancy are implemented, then the reliability of sensory data transmission is improved, but the cost increases significantly
Solution Approach 1:
The solution employs inexpensive, simple components such as a light emitting device (LED) and basic imaging capabilities already present in the vehicle. Rather than investing in expensive, high-speed redundant communication infrastructure, the patent uses low-cost visual encoding that can be implemented with minimal additional hardware, making the system economically viable while still providing verification of data integrity.
3Speed
If image-to-image latency is reduced for timely vehicle operation, then the responsiveness of remote control is improved, but the risk of transmission errors and rendering issues increases
Solution Approach 1:
The light emitting device provides visual feedback information (encoded pattern) that allows the remote operator to verify whether the captured image frame accurately represents the current vehicle surroundings. This feedback mechanism enables real-time verification of data integrity without requiring slower, more reliable communication protocols, thus maintaining high speed while improving reliability through verification.
