Solution Overview
Problem
Existing methods for creating three-dimensional shape models of hands in Mixed Reality technology require manual input of dimension data, which is time-consuming, prone to errors, and inaccurate, especially for complex shapes like hands.
Innovation Solution
An information processing apparatus that captures images of a finger using stereo cameras, estimates the three-dimensional shape, and automatically measures dimensions to generate a three-dimensional model, reducing the need for manual input and improving accuracy.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If manual measurement and input of dimension data is performed, then the three-dimensional model can be created, but the process requires much time and effort
Solution Approach 1:
The patent replaces the manual mechanical process of measuring and inputting dimension data with an automated image processing system. The system captures images of the finger, automatically detects contours and calculates three-dimensional shape information through computational algorithms, eliminating the need for manual measurement and data entry operations.
Solution Approach 2:
The patent creates a digital copy (three-dimensional model) of the finger by capturing its visual appearance through images. Instead of manually measuring physical dimensions, the system creates a computational representation that can be processed automatically, allowing rapid generation of accurate shape data without physical contact or manual intervention.
2Reliability
If manual input of dimension data is performed, then the three-dimensional model can be created, but typing errors or input errors may occur
Solution Approach 1:
The patent eliminates manual data input operations entirely by replacing them with automated image processing. The system captures images and uses computational algorithms to directly extract dimension data, removing the human operator from the data entry process and thereby eliminating typing errors and input mistakes.
Solution Approach 2:
The system performs self-measurement by automatically analyzing its own captured images to extract dimension data. The image processing apparatus independently calculates three-dimensional shape information from the captured images without requiring external manual input, ensuring data accuracy through automated computation rather than human entry.
3Ease of manufacture
If separate measurement of dimension data is performed, then the three-dimensional model can be created, but the process becomes complex and time-consuming
Solution Approach 1:
The patent merges the measurement process with the model creation process into a single integrated operation. By capturing images that contain both visual appearance and dimensional information simultaneously, the system eliminates the need for separate measurement steps, simplifying the overall process while maintaining accuracy.
Solution Approach 2:
The image processing apparatus performs multiple functions simultaneously: it captures the visual appearance of the finger, extracts dimensional information, and generates the three-dimensional model all in one operation. This multi-functional approach eliminates the need for separate specialized measurement devices and procedures.

AI summary
An information processing apparatus comprises a determination unit configured to analyze a captured image of a finger and determine whether the captured image is a captured image appropriate to measure a dimension of a part of the finger; a measuring unit configured to measure a dimension of the finger using the captured image determined to be appropriate by the determination unit; and a generation unit configured to generate a model of a three-dimensional shape of the finger using information of the dimension.
