Engineering Contradiction Analysis
1Manufacturing precision
If conventional photogrammetry methods are used for 3D modeling, then 3D models can be generated from multiple captured images, but the quality of the generated 3D model decreases when imaging parameters are not appropriate
Solution Approach 1:
The system performs preliminary 3D modeling to generate initial 3D model data before the actual imaging process. Based on this preliminary model, it calculates optimal imaging positions and orientations, allowing the imaging parameters to be predetermined and optimized before capture, thereby ensuring high 3D model quality without requiring complex real-time parameter adjustments
Solution Approach 2:
The system uses the generated 3D model data as feedback to evaluate and determine appropriate imaging parameters. By analyzing the preliminary 3D model, the system can identify which imaging parameters (position, orientation, etc.) need to be adjusted to achieve the desired quality level, creating a closed-loop optimization process
2Object-generated harmful factors
If shadow removal methods are applied to processed texture information, then shadows can be removed from the 3D model, but the reduction in 3D model quality cannot be sufficiently suppressed
Solution Approach 1:
The system performs preliminary 3D modeling and illumination environment detection before final image capture. By detecting the illumination environment in advance and calculating optimal imaging parameters based on the preliminary 3D model, the system prevents shadow formation at the source rather than attempting to remove shadows afterward, thereby maintaining 3D model quality
Solution Approach 2:
The system takes preliminary action to counteract shadow formation by detecting illumination environments and adjusting imaging parameters before capture. By positioning the imaging unit according to calculated optimal positions and orientations, the system prevents harmful shadows from being generated in the first place, rather than dealing with them in post-processing
3Manufacturing precision
If imaging parameters are controlled based on position and orientation information and first 3D shape information, then the quality of generated 3D models is improved, but the complexity of the imaging system increases
Solution Approach 1:
The system performs self-service by automatically generating 3D model data from captured images and using this data to determine optimal imaging parameters for subsequent captures. The imaging control unit automatically adjusts positions and orientations based on the generated 3D model, eliminating the need for manual parameter setting and reducing operational complexity while maintaining high quality
Solution Approach 2:
The imaging unit serves multiple functions: it captures images for 3D modeling, detects illumination environments, and positions itself based on calculated optimal parameters. The system integrates multiple functions (imaging, detection, control) into a unified platform, reducing overall system complexity despite the advanced capabilities

AI summary
The present disclosure relates to an information processing device and method to make it possible to reduce a decrease in quality of a 3D model generated using a captured image. An imaging parameter applied to imaging for generating a captured image to be used for generation of second three-dimensional shape information is controlled on the basis of position and orientation information indicating a position and an orientation of an imaging unit and first three-dimensional shape information. Furthermore, an illumination environment of a space in which imaging is performed is detected, imaging for generating a captured image to be used for generation of three-dimensional shape information expressing a three-dimensional shape of a 3D object is performed in the space, and information regarding the detected illumination environment is associated with the captured image. The present disclosure is applicable to, for example, an information processing device, an imaging device, an imaging communication device, electronic equipment, an information processing method, a program, an information processing system, or the like.
