Spatial 3D Display Viewpoint Control to Prevent Model Protrusion
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing spatial reproduction displays can cause discomfort due to 3D models protruding from the display space, leading to a deterioration in stereoscopic effect.
Innovation Solution
An information processing apparatus with a viewpoint position determining unit, region-of-interest specifying unit, and display control unit adjusts the position and size of 3D models within the display space to prevent protrusion, using a spatial reproduction display to ensure optimal visibility.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If a 3D model is displayed with large size and close distance to viewpoint, then visibility and stereoscopic effect are improved, but the model may protrude from the display space causing user discomfort
Solution Approach 1:
The patent implements dynamic adjustment of the 3D model's position and size based on real-time detection of model coordinates and display space boundaries. The system continuously monitors whether the model protrudes from the display space and automatically adjusts its rendering parameters to maintain optimal visibility while preventing harmful protrusion, thereby resolving the contradiction between stereoscopic effect quality and display space compliance.
2Measurement precision
If the position of a 3D model is adjusted to the display surface depth position, then visibility is improved, but the model may still protrude from the display space
Solution Approach 1:
The patent employs a feedback mechanism where the system detects the coordinates of the 3D model and compares them against the display space boundaries. Based on this feedback, the system determines whether the model protrudes from the display space and automatically adjusts its position and size accordingly. This closed-loop control ensures that visibility is maintained while preventing model protrusion, overcoming the limitations of fixed depth position adjustment.

AI summary
Provided is an information processing apparatus and an information processing method that stereoscopically displays a 3D model by a spatial reproduction display. The information processing apparatus determines, in 3D content presented by a spatial reproduction display that stereoscopically displays a 3D model, a viewpoint position with respect to the 3D model, determines a region of interest including at least a part of the 3D model, acquires a size of a display space for displaying the 3D model, changes, using the 3D model included in the region of interest as a 3D model of interest, a position of the 3D model of interest with respect to the viewpoint position to a position located within the display space on the basis of the viewpoint position, the region of interest, and the size of the display space, and causes the spatial reproduction display to stereoscopically display the 3D model.
