Probe Observing Device Digital Zoom Alignment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing surface texture measuring devices face challenges in achieving high measuring accuracy and efficiency due to the difficulty in visually observing precision probes, as high-magnification lenses narrow the view field, making it time-consuming to adjust the probe into the camera's view, while low-magnification lenses lack sufficient clarity for precise positioning.
Innovation Solution
A probe observing device with an image processing unit that performs digital zoom on the probe's image, allowing for clear observation and simplifying the adjustment process by using a low-magnification lens system with a wider view field, and a three-axis-orthogonal driving mechanism for easy alignment, along with an operating device for region selection and enlargement instructions to center and magnify the probe on the display.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If a high-magnification lens is used to observe the probe, then the observation clarity is improved, but the view field narrows making it time-consuming to adjust the probe into the camera's view
Solution Approach 1:
The observation process is segmented into two stages: first using a low-magnification lens to quickly locate and center the probe in the view field, then switching to a high-magnification lens for detailed observation. This segmentation resolves the contradiction by applying different magnification levels at different stages of the observation process.
Solution Approach 2:
The probe is preliminarily positioned and centered in the camera's view field using a low-magnification lens before switching to high-magnification observation. This preliminary action with a wider view field eliminates the time-consuming adjustment problem when using high magnification.
2Ease of operation
If a low-magnification lens is used to widen the view field, then the adjustment process is simplified, but the observation clarity is insufficient for precise positioning
Solution Approach 1:
The system dynamically switches between low-magnification and high-magnification lenses based on the observation stage. The magnification level is not fixed but changes according to whether the task requires wide-field adjustment or detailed observation, resolving the contradiction between ease of operation and observation clarity.
Solution Approach 2:
The magnification parameter of the lens is changed between two states: low magnification for easy adjustment and high magnification for clear observation. This parameter change allows the system to optimize for different operational requirements at different times.
3Measurement precision
If a high-magnification lens is used to observe the probe, then the measuring accuracy is improved, but the device complexity increases due to the need for precise alignment mechanisms
Solution Approach 1:
The complex alignment and positioning functions are extracted from the mechanical domain and transferred to the image processing domain. Instead of using complex mechanical alignment mechanisms, the system captures the probe image and uses image processing techniques to locate and center the probe, thereby reducing mechanical complexity while maintaining measurement precision.
Solution Approach 2:
The mechanical alignment system is replaced with an image-based alignment system. Rather than relying on complex mechanical mechanisms to precisely position the probe in the view field, the system uses the camera to capture the probe image and processes this image to determine the probe's position and center it, substituting mechanical complexity with optical and computational simplicity.
