Image Measurement Device Automatic Probe Positioning
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional image measurement devices require manual designation of contact target positions for a probe, which is cumbersome and prone to errors, especially when dealing with complex shapes like circles and arcs, as users struggle to accurately determine where the probe should contact the workpiece.
Innovation Solution
An image measurement device that uses a model image to automatically identify contact target positions based on the shape and size of measurement elements, with a display section showing a model image generated from design data or captured images, allowing users to designate measurement elements and automatically determine the probe's scan operation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If manual designation of contact target positions is used, then users can specify measurement positions, but the operation becomes cumbersome and error-prone
Solution Approach 1:
The measurement element automatically designates multiple contact target positions for the probe based on its own geometric features (circles, arcs, straight lines). The measurement element serves itself by generating the contact target position information without requiring manual intervention, thereby simplifying operation while maintaining measurement precision.
Solution Approach 2:
The contact target positions are predetermined based on the measurement element's geometry before the actual measurement process. By pre-calculating and storing the contact target positions associated with the measurement element, the system eliminates the need for manual designation during operation, reducing both complexity and potential errors.
2Adaptability or versatility
If probe contact measurement is used for complex shapes, then measurement can be performed, but determining contact positions becomes difficult
Solution Approach 1:
The patent replaces the manual mechanical process of determining contact positions with an automated computational geometry system. The measurement element's geometric data (circles, arcs, straight lines) is processed algorithmically to automatically generate contact target positions, eliminating the difficulty of manual determination while maintaining versatility for complex shapes.
Solution Approach 2:
The measurement element acts as an intermediary between the workpiece geometry and the probe measurement process. By using the measurement element's predefined geometric features as a mediator, the system automatically translates complex workpiece shapes into actionable contact target positions, simplifying the measurement process while maintaining adaptability.

AI summary
There are included a display section for displaying a model image, an input receiving section for receiving designation, in the model image, of a measurement element for which measurement is to be performed by the probe, a storage section storing, in advance, an arrangement rule defining a relationship between a shape type or a size of a measurement element and arranged positions of contact target positions of the probe, and a measurement control section for identifying, at a time of measurement execution, contact target positions of the probe based on a position of the measurement element designated by the input receiving section, a shape type or a size of the measurement element, and the arrangement rule that is stored in the storage section, and for controlling a horizontal drive section so that the probe sequentially moves to the plurality of contact target positions identified.
