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, which require manual and incomplete removal, leading to incomplete 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, ensuring precise modeling by excluding jig and adhesive-member images.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Measurement precision

If the scan region is arbitrarily adjusted to remove jig and adhesive-member images, then some unwanted images may be removed, but the jig and adhesive-member images are not completely removed and portions of the target object image may be inadvertently removed

Engineering Contradiction:

Improveprecision of three-dimensional modelVSAvoidease of setting scan region

Core Design Contradiction:

Measurement precisionVSEase of operation

Solution Approach 1:

The system automatically identifies and sets the scan region by detecting the target object image boundaries and calculating the appropriate region, eliminating the need for manual user adjustment. The control unit performs self-service by autonomously determining which portions of the input region contain the target object and configuring the scan region accordingly, thus resolving the contradiction between precision and ease of operation.

Inventive Principle:

Principle #25Self-service

Solution Approach 2:

The manual mechanical adjustment of scan region boundaries by the user is replaced with an automated image processing and detection system. The control unit uses image analysis algorithms to automatically identify the target object, calculate its boundaries, and set the scan region, substituting manual operation with automated computational processing to achieve both precision and ease of use.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

2Measurement precision

If the user manually deletes jig and adhesive-member images, then some unwanted elements may be removed, but complete removal is difficult and time-consuming

Engineering Contradiction:

Improvepurity of target object modelVSAvoidtime for manual image deletion

Core Design Contradiction:

Measurement precisionVSLoss of time

Solution Approach 1:

The control unit automatically performs the function of identifying and excluding jig and adhesive-member images from the scan region without requiring manual user intervention. The system serves itself by autonomously analyzing the input region, detecting unwanted elements, and configuring the scan region to exclude them, thereby achieving complete removal while eliminating time loss.

Inventive Principle:

Principle #25Self-service

Solution Approach 2:

The unwanted jig and adhesive-member images are extracted and excluded from the scan region through automated detection. The control unit identifies these unwanted elements and removes them from the processing area by setting appropriate scan region boundaries, achieving complete separation of target object from unwanted elements without manual time-consuming deletion.

Inventive Principle:

Principle #2Taking out (Extraction)

3Measurement precision

If the scan region includes the entire input region to ensure complete target object capture, then no target object portions are missed, but jig and adhesive-member images are also included causing modeling errors

Engineering Contradiction:

Improvecompleteness of target object modelVSAvoidcontamination by unwanted images

Core Design Contradiction:

Measurement precisionVSObject-generated harmful factors

Solution Approach 1:

Instead of applying a uniform scan region across the entire input region, the system applies local quality control by detecting the specific location and boundaries of the target object image. The scan region is locally adjusted to match the target object's spatial extent, ensuring complete capture of the target while automatically excluding unwanted jig and adhesive-member images located in different regions.

Inventive Principle:

Principle #3Local quality

Solution Approach 2:

The input region is segmented into multiple zones based on image content analysis. The control unit divides the input region to identify where the target object is located versus where unwanted elements are present, then configures the scan region to cover only the target object segment, thereby achieving complete target capture while excluding harmful unwanted images.

Inventive Principle:

Principle #1Segmentation

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.
