Polygon Vertex Selection for Display Calibration
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing display systems face difficulties in accurately selecting and adjusting multiple characteristic points on an image, particularly when the search range is large or when desired points deviate from the selection range, leading to incorrect selections and reduced user convenience.
Innovation Solution
A display method that includes displaying a pattern image with a point group and line segment group, allowing users to input positions to select the smallest overlapping polygon, with marks indicating selected vertexes, enabling precise selection and adjustment of image points.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If the search range is set large to cover more characteristic portions, then the coverage area increases, but incorrect or unwanted characteristic portions are selected
Solution Approach 1:
The search range is divided into multiple rectangular regions (first rectangle, second rectangle, third rectangle, fourth rectangle) formed by vertical and horizontal lines. Each rectangle contains specific characteristic portions, allowing the system to segment the selection into manageable units and prevent unwanted selections by limiting each selection to its designated rectangular region.
2Measurement precision
If the search range is set small to improve selection accuracy, then the selection precision improves, but characteristic portions deviating from the range cannot be selected
Solution Approach 1:
The system provides multiple selection modes: single-rectangle selection for precise local adjustments, multi-rectangle selection for covering dispersed characteristic portions, and free-form polygon selection for irregular regions. This multi-functional approach allows users to adapt the selection method to different scenarios, whether needing high precision or broad coverage.
3Measurement precision
If multiple characteristic portions are selected individually, then the selection precision for each point improves, but the operation time increases
Solution Approach 1:
Multiple vertices are merged into a single selectable unit through the polygon selection feature. When users define a polygon by selecting vertices, all vertices within that polygon are selected simultaneously through one operation, combining multiple selection actions into one and significantly reducing operation time while maintaining precise vertex selection.
Solution Approach 2:
The system performs preliminary grouping of vertices into polygons before the user completes the selection. As users sequentially click vertices, the system temporarily stores them and automatically closes the polygon when the starting vertex is reached or when a sufficient number of vertices are collected, preparing the complete vertex set in advance for immediate processing.
4Adaptability or versatility
If a free-form polygon selection is allowed, then the selection flexibility improves, but the device complexity increases
Solution Approach 1:
Instead of allowing free-form polygon drawing with complex coordinate input, the system inverts the approach: users simply click on existing characteristic portions (vertices) and the system automatically connects them to form the polygon. This reverses the complexity from the drawing mechanism to the automatic vertex connection logic, maintaining flexibility while simplifying user interaction.

AI summary
A second controller executes processing including displaying a pattern image including a plurality of control points and a plurality of line segments connecting control points of the plurality of control points, receiving an input indicating a first position on the pattern image, selecting at least two vertexes of a smallest first polygon overlapping the first position among polygons formed by the plurality of line segments, and displaying mark images indicating that the at least two vertexes were selected.
