Vehicle Image Frame Encoding for Remote Terminal Verification
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing communication systems in remote-operated vehicles face challenges in ensuring accurate and secure representation of vehicle surroundings, leading to potential operational risks due to inadequate image-to-image latency, incorrect data transmission, or erroneous rendering, which existing complex and expensive systems fail to adequately address.
Innovation Solution
A method and system that encodes predetermined information as a visible pattern on image frames transmitted from the vehicle to the remote terminal, allowing for verification of correct data transmission and rendering, and includes features like timestamp encoding, message authentication, and emergency fail-safe procedures to ensure safe operation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If complex communication systems with sufficient speed and redundancy are implemented, then transmission reliability is improved, but device complexity and cost increase
Solution Approach 1:
The patent uses visual encoding of data into color patterns that are displayed on the vehicle's external surfaces. The vehicle's skin or external panels change color or display colored patterns representing encoded information, allowing remote terminals to read data visually without complex communication protocols
Solution Approach 2:
The patent creates visual copies of data in the form of color patterns on the vehicle exterior. Instead of transmitting raw data through complex communication channels, the system encodes and displays visual representations that can be captured and decoded by remote terminals, simplifying the transmission mechanism
2Loss of time
If image-to-image latency is reduced for timely vehicle operation, then response time is improved, but transmission speed requirements increase system complexity
Solution Approach 1:
The system pre-encodes data into visual color patterns that are displayed on the vehicle exterior in advance. This preliminary encoding allows remote terminals to capture and process information as the vehicle moves through their field of view, eliminating the need for high-speed real-time transmission systems
Solution Approach 2:
The patent replaces electronic communication transmission mechanisms with optical visualization. Instead of using complex high-speed data transmission systems, the invention uses visual color patterns that can be captured by cameras and processed at the remote terminal, substituting mechanical/electronic transmission with optical detection
3Measurement precision
If sensory data transmission is ensured to be correct, then data accuracy is improved, but transmission verification complexity increases
Solution Approach 1:
The system implements feedback by encoding verification data directly into the visual color patterns displayed on the vehicle. Remote terminals can read these patterns and verify data integrity through the encoded information, creating a self-verifying transmission system without complex external verification infrastructure
Solution Approach 2:
The patent merges data transmission and verification into a single visual encoding process. The color patterns on the vehicle exterior simultaneously carry both the primary data and verification information, eliminating the need for separate verification transmission channels
