Solution Overview
Problem
Conventional 3D modeling methods face challenges in accurately determining the optimal position and attitude for imaging to minimize the number of captured images, leading to increased workload and processing time without ensuring sufficient accuracy.
Innovation Solution
An information processing device and method that generates initial 3D shape information from a first captured image, evaluates the accuracy of subsequent images using scoring, and provides guidance for subsequent imaging to improve positioning and attitude, thereby reducing the workload and processing amount while enhancing accuracy.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If conventional 3D modeling methods are used without optimization, then the number of captured images increases, but the accuracy of 3D data generation deteriorates and workload increases
Solution Approach 1:
The system performs preliminary 3D modeling using a small number of initial captured images to generate preliminary 3D data. This preliminary action provides a foundation for subsequent optimization, allowing the system to evaluate imaging quality and guide additional capture operations only where needed, rather than capturing a large number of images uniformly from the outset
Solution Approach 2:
The system evaluates the preliminary 3D data to generate imaging quality information, which provides feedback on the sufficiency and quality of captured images. This feedback mechanism enables the system to determine whether additional images are needed and from which viewpoints, thereby optimizing the total number of captured images while ensuring adequate 3D reconstruction accuracy
2Measurement precision
If more captured images are taken to improve accuracy, then the accuracy of 3D data generation is improved, but the workload and processing time increase
Solution Approach 1:
The system performs preliminary 3D modeling with a minimal set of initial images to establish a baseline 3D model. This preliminary action allows the system to assess reconstruction quality early and determine the minimum necessary additional imaging required, avoiding unnecessary processing of excess images and reducing overall processing time
Solution Approach 2:
Instead of uniformly capturing images from all possible viewpoints, the system applies partial action by focusing additional capture operations only on specific viewpoints identified as insufficient by the evaluation process. This targeted approach achieves necessary accuracy without the time cost of comprehensive uniform sampling
3Measurement precision
If photographers attempt to image from optimal positions and attitudes, then the accuracy of 3D data is improved, but it is difficult to ascertain the appropriate position and attitude
Solution Approach 1:
The system automatically evaluates preliminary 3D reconstruction quality and generates specific imaging quality information that provides feedback on which viewpoints are insufficient. This feedback replaces the need for photographer expertise in determining optimal positions, as the system objectively identifies which perspectives are needed based on actual reconstruction performance
Solution Approach 2:
The system performs self-evaluation of the 3D reconstruction quality using the captured images themselves. By automatically assessing whether the current set of images produces adequate 3D data and identifying specific gaps, the system eliminates the need for external expert judgment, making the process accessible to ordinary users without specialized knowledge

AI summary
The present disclosure relates to an information processing device and a method capable of performing 3D modeling more easily. On the basis of a first captured image generated by first imaging of a 3D object, first three-dimensional shape information is generated. Using the first three-dimensional shape information, an accuracy of second three-dimensional shape information that can be generated using second captured images generated from second imaging performed thus far is evaluated, and a scoring result is generated. On the basis of the scoring result, the second imaging is controlled, or guidance information for the second imaging is generated and controlled to be output.
