Measurement Device Dimension Adjustment via Depth Color Fusion
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing measurement devices face challenges in accurately determining the dimensions of objects with multiple planes, particularly when using infrared cameras, as they struggle with detecting depth in gaps, uneven surfaces, and black materials, leading to noisy or missing data and reduced accuracy.
Innovation Solution
A measurement device that combines depth and color information to calculate the dimensions of an object's outer shape, allowing users to adjust the dimensions of selected planes by inputting a change amount, which recalculates and displays the updated dimensions based on user input, enabling precise adjustment of the object's dimensions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If depth information is acquired using infrared camera, then measurement speed is improved, but measurement precision deteriorates due to noisy or missing data from gaps, uneven surfaces, and black materials
Solution Approach 1:
The object is divided into multiple planes, and each plane's dimensions are adjusted independently. This allows selective refinement of specific regions with measurement errors without reprocessing the entire object, thus maintaining speed while improving precision where needed.
Solution Approach 2:
The system provides feedback by displaying the initial measurement results and allowing users to visually compare with the actual object. Users can then input correction amounts based on visual inspection, creating a feedback loop that refines measurement precision while maintaining the speed advantage of infrared imaging.
2Ease of operation
If automatic dimension calculation is performed based on depth information, then ease of operation is improved, but measurement precision deteriorates due to inability to correct detection errors
Solution Approach 1:
The measurement system transitions from a static automatic calculation mode to a dynamic adjustable mode. Users can select specific planes and adjust their dimensions interactively, making the system adaptable to correct errors while preserving the ease of automatic initial measurement.
Solution Approach 2:
The system enables user self-correction of measurement errors. Users can visually inspect the measured dimensions against the actual object and directly input correction amounts, allowing them to service their own measurement needs without requiring complex automated error detection algorithms.
3Productivity
If all planes of the object are measured simultaneously, then productivity is improved, but ease of repair deteriorates due to inability to selectively adjust specific planes
Solution Approach 1:
The measurement system segments the object into multiple independently adjustable planes. This allows users to select and correct errors in specific planes without having to reprocess or adjust other planes, providing repair flexibility while maintaining overall measurement efficiency.
Solution Approach 2:
Each plane can be adjusted with local quality - specific planes can be selected and modified based on where errors occur. This localized adjustment capability allows efficient correction of specific measurement errors without affecting the measurement or adjustment of other planes.

AI summary
A measurement device includes: an operation unit that receives an operation of a user; an acquisition unit that acquires depth information indicating a depth image and color information indicating a color image of an object; a controller that calculates, based on at least one of the depth information and the color information, first dimension of the object; and a display unit that displays a frame image showing a contour shape of the object to be superimposed on the color image, the contour shape being based on the first dimension. The operation unit receives a selection and an input of a change amount of the adjustment target plane by the user. The controller calculates, second dimension of the object when the adjustment target plane is moved in a normal direction based on the change amount, and changes the frame image to show a contour shape based on the second dimension.
