3D Scanner Scan Region Setting for Accurate Object Modeling
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing three-dimensional scanning technologies face challenges in acquiring precise models due to the inclusion of jig and adhesive-member images in the scanning process, leading to incomplete or inaccurate three-dimensional models.
Innovation Solution
A method is provided to automatically set a scan region by determining a predetermined upper portion of the jig image as the scan region, aligning the target object image at a predetermined point, and generating a three-dimensional model based on this region, thereby excluding jig and adhesive-member images.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If the scan region is arbitrarily adjusted to remove jig image and adhesive-member image, then the jig image and adhesive-member image can be removed from the three-dimensional modeling process, but the jig image and adhesive-member image are not completely removed and at least one portion of the target object image is inadvertently removed
Solution Approach 1:
The system automatically determines the scan region by detecting the target object image and calculating the region boundaries without user intervention. The control unit autonomously identifies the target object's position and size, then sets the scan region to include only the target object image, excluding jig and adhesive-member images. This self-service approach eliminates manual adjustment while ensuring precise region selection.
Solution Approach 2:
The manual mechanical adjustment of scan region boundaries by the user is replaced with an automated image processing system. The control unit uses image analysis algorithms to detect the target object image and automatically calculates the scan region boundaries based on the detected image parameters, substituting human operation with computational processing.
2Productivity
If the user manually deletes the jig image and adhesive-member image, then the three-dimensional modeling process can be simplified, but the process becomes time-consuming and error-prone
Solution Approach 1:
The scan region is determined in advance before the three-dimensional modeling process begins. The control unit analyzes the input image to identify the target object image and pre-calculates the scan region boundaries, ensuring that only the target object image is included in the modeling process. This preliminary action prevents jig and adhesive-member images from being included in the first place, eliminating the need for manual deletion.
Solution Approach 2:
The system extracts only the relevant target object image from the input image by automatically determining the scan region boundaries. The control unit identifies the target object image and extracts it from the surrounding jig and adhesive-member images, creating a clean scan region that contains only the necessary information for three-dimensional modeling.

AI summary
Provided is a method of setting a scan region, the method including: placing a target object on an upper surface of a jig of a three-dimensional scanner in such a manner that at least one portion of a target object image representing a shape of the target object is plotted on an input region; determining, by a control unit, a predetermined upper portion of the input region, as a scan region, from a jig image representing the shape of the jig; and generating, by the control unit, a three-dimensional model of the target object on the basis of the target object image resulting from scanning the scan region.
