Visual Probe Control for Position Measuring Devices
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing position measuring devices require practice and professional knowledge to accurately and quickly designate detection points, especially when moving a probe in three-dimensional space or following programmed movements, as they rely on complex input devices like joysticks.
Innovation Solution
An operation method that uses a terminal device with an image acquisition and display part to visually guide the movement of a measurement head, allowing intuitive control through tracking instructions, touch sensors, and three-dimensional position detection to facilitate precise and rapid positioning of the probe without direct contact.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a joystick is used to operate the probe in three-dimensional space, then the measurement device can be controlled to move in XYZ directions and rotate the probe, but the operation requires extensive practice to accurately and quickly designate detection points
Solution Approach 1:
The patent replaces the mechanical joystick control system with an optical/image-based control system. The probe position is visualized on a display device, and the operator controls the probe by touching or interacting with the displayed image, substituting mechanical manipulation with visual-guided digital control. This eliminates the need for practice to master joystick movements while maintaining precise three-dimensional positioning capability.
2Productivity
If automatic movement of the measurement head is performed according to a program, then measurement efficiency is improved, but highly professional knowledge is required for program setting
Solution Approach 1:
The patent creates a visual copy or representation of the probe position and measurement environment on a display device. This visual model allows operators to plan and control measurement paths by interacting with the displayed image rather than writing complex programs. The system translates visual interactions into automated movement instructions, enabling efficient measurement execution without requiring professional programming knowledge.
3Measurement precision
If precise control of the probe position is achieved through complex input devices, then measurement accuracy is improved, but the device complexity increases
Solution Approach 1:
The patent introduces a display device as an intermediary between the operator and the probe control system. The display shows the probe position and target detection points, serving as a visual mediator that simplifies the control interface. Instead of complex mechanical input devices, the system uses touch or digital interaction with the visual display to control probe movement, maintaining measurement precision while reducing control system complexity.

AI summary
To provide an operation method of a position measuring device capable of accurately and quickly designating a detection point of an object by intuitive operability, such as directly moving the probe with a hand. One aspect of the present invention is an operation method of a position measuring device that includes a measurement head having a probe for designating a detection point of a position of an object, and a moving mechanism for moving the measurement head, and acquires a coordinate of the detection point designated by the probe. The operation method of a position measuring device includes the steps of: using a terminal device including an image acquisition part and a display part to acquire an image of the probe by the image acquisition part and display the image on the display part; detecting a relative positional relation between the probe and the terminal device when having received a movement instruction by the terminal device in a state where an image of the probe is displayed on the display part; and performing a movement control of the measurement head following the movement instruction received by the terminal device by actuating the moving mechanism on the basis of the positional relation.
