Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current information processing systems lack the ability to allow users to observe a three-dimensional region from various positions effectively, with existing solutions failing to accurately determine and display the intended viewpoint position within the region.
Innovation Solution
An information processing apparatus and method that acquires and processes images of a three-dimensional region, using coordinates and observation states to generate virtual viewpoint images, allowing users to observe the region from intended positions by determining the viewpoint position based on indicated positions within the region, and displaying these images on user devices.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a virtual viewpoint is moved to a predetermined movement area when the distance is within a threshold, then the user can observe the three-dimensional region from various positions, but the system complexity increases due to multiple threshold judgments and viewpoint management
Solution Approach 1:
The patent pre-divides the three-dimensional region into multiple movement areas and sets predetermined viewpoint positions in advance. When a user selects a movement area, the system directly switches to the pre-configured viewpoint without requiring real-time calculation or complex judgment, thus reducing system complexity while maintaining versatile observation capability.
2Stability of the object's composition
If the virtual viewpoint is not moved when the distance exceeds a threshold, then the system maintains stability, but the user experience deteriorates due to limited viewpoint adjustment
Solution Approach 1:
The patent implements dynamic viewpoint adjustment based on distance thresholds. When the distance between the virtual viewpoint and the selected movement area is within the threshold, the viewpoint automatically moves to provide flexible adjustment. When the distance exceeds the threshold, the viewpoint remains stable. This dynamic response balances stability and flexibility, improving user experience without causing excessive viewpoint hopping.
3Measurement precision
If multiple imaging apparatuses are used to capture the three-dimensional region, then the observation accuracy and coverage improve, but the device complexity and cost increase
Solution Approach 1:
The patent combines images captured by multiple imaging apparatuses positioned at different locations within the three-dimensional region. By merging these multiple perspectives into a unified virtual viewpoint system, the patent achieves high observation accuracy and comprehensive coverage without requiring each individual imaging device to be overly complex. The coordination of multiple simple imaging apparatuses replaces the need for a single complex high-precision system.

AI summary
An information processing apparatus includes a processor, and a memory built in or connected to the processor, in which the processor acquires a subject image showing a subject present inside a three-dimensional region, which is an observation target, in a case in which an inside of the three-dimensional region is observed from a viewpoint position determined based on coordinates inside the three-dimensional region corresponding to an indication position that is indicated inside the three-dimensional region or that is indicated inside a reference image showing a state of the inside of the three-dimensional region in a case in which the inside of the three-dimensional region is observed from a reference position.
