Automatic Operation Vehicle Triangulation for Marker-Based Area Setting
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing automatic operation vehicles require significant user labor to set operation areas, as they need to be guided along boundaries to acquire and store position information, which is inefficient and time-consuming.
Innovation Solution
An automatic operation vehicle equipped with cameras, sensors, and an electronic control unit that uses triangulation to acquire marker position information, allowing it to autonomously determine its operating area without physical barriers, thereby reducing user intervention and improving marker position information acquisition accuracy.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Extent of automation
If the automatic operation vehicle is guided along the boundary to acquire position information, then the operation area can be set, but the user labor and time consumption increase significantly
Solution Approach 1:
The system performs preliminary action by pre-setting multiple candidate operation areas based on marker positions before the user needs to set the actual operation area. The electronic control unit stores these candidate areas in advance, so when the vehicle needs to set an operation area, it can directly select from pre-computed options rather than requiring the user to guide the vehicle along boundaries to acquire position information.
Solution Approach 2:
The system creates copies of potential operation area definitions based on marker configurations. Instead of requiring the user to physically define the operation area by guiding the vehicle along boundaries, the system generates multiple candidate area copies from the stored marker position information, allowing rapid selection without time-consuming manual boundary tracing.
2Reliability
If physical barriers are used to define operation area, then the boundary can be clearly marked, but the user needs to place barriers throughout the entire boundary
Solution Approach 1:
The system replaces the mechanical system of physical barriers with an optical/electronic system using markers and camera-based detection. Instead of requiring users to physically install and arrange barrier objects along the entire boundary, the system uses easily placeable markers that are detected by the vehicle's camera and processing unit, automatically defining the operation area boundaries through computational methods.
Solution Approach 2:
The system changes the parameter of boundary definition from physical barrier placement to marker position coordinates. By transforming the boundary definition method from a mechanical placement task to a coordinate-based computational task, the system allows boundaries to be defined by simple marker positions rather than requiring continuous physical barrier installation along the entire perimeter.
3Measurement precision
If the user guides the vehicle along the boundary, then the operation area can be accurately determined, but the process becomes labor-intensive and inefficient
Solution Approach 1:
The system implements self-service by enabling the vehicle to automatically acquire and process marker position information using its own camera and electronic control unit. Instead of requiring user guidance along the boundary, the vehicle independently captures images, processes the marker positions, and determines the operation area boundaries autonomously, significantly improving efficiency while maintaining accuracy.
Solution Approach 2:
The system introduces an intermediary processing layer between the markers and the operation area definition. The electronic control unit acts as an intermediary that automatically processes marker position data from camera images, calculates boundary coordinates, and determines the operation area without requiring direct user intervention or manual boundary tracing, thereby maintaining precision while boosting productivity.

AI summary
An automatic operation vehicle that automatically performs an operation in an operation area is provided. A survey unit acquires the position information of the marker using a first angle between the moving direction and a direction to the marker from a first point through which the vehicle passes during the movement in a constant moving direction, a second angle between the moving direction and a direction to the marker from a second different point through which the vehicle passes during the movement in the moving direction, and a distance between the first point and the second point. The survey unit determines the first point and/or the second point during the movement of the vehicle in the moving direction such that the angle difference between the first angle and the second angle becomes close to 90°.
