Unmanned Vehicle Control Using Landmark Verification
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing systems face errors in determining whether an intended target is being controlled due to similar operations by target and non-target vehicles, leading to potential misidentification and unintended vehicle movement.
Innovation Solution
A control device utilizing a camera to detect two-dimensional codes as landmarks, combined with a determination unit to verify the presence of these landmarks, preventing erroneous control by confirming the intended target through accurate detection and notification of abnormalities.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If remote control commands are transmitted to move vehicles, then vehicle automation and productivity are improved, but errors in determining the intended target occur when multiple vehicles perform the same operation simultaneously
Solution Approach 1:
The patent implements a feedback mechanism where the detector (camera) captures images of landmarks (two-dimensional codes) on vehicles, and the determination unit verifies whether the detected landmark matches the intended target. This closed-loop feedback system confirms target identity before executing control commands, preventing erroneous control of wrong vehicles while maintaining automated operation efficiency.
2Ease of operation
If simple operation commands are used for remote control, then ease of operation is improved, but the ability to accurately distinguish between multiple target vehicles deteriorates
Solution Approach 1:
The patent introduces an intermediary verification system consisting of landmarks (two-dimensional codes) attached to vehicles and a determination unit that checks whether the detected landmark corresponds to the intended target. This intermediary mechanism enables simple remote control operations while ensuring accurate vehicle identification through the landmark verification step before command execution.
3Reliability
If landmark detection is added to verify target identity, then target identification accuracy is improved, but device complexity increases due to additional detectors and determination units
Solution Approach 1:
The patent uses two-dimensional codes (landmarks) as simplified copies or representations of vehicle identity information. Instead of complex vehicle recognition systems, the system captures images of these simple code patterns using a camera and verifies them through image processing. This copying approach maintains high identification accuracy while minimizing additional device complexity.

AI summary
A control device includes: an acquisition unit configured to acquire a detection result by a detector, wherein the detector is mounted on a moving object movable by unmanned driving; a determination unit configured to determine a landmark to be detected by the detector, wherein the landmark is located outside the moving object; and a control unit configured to move the moving object by unmanned driving, wherein the control unit performs different processing for moving the moving object depending on whether or not the landmark determined by the determination unit is included in the detection result.
