3D Text Placement Using Parallax Information
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current methods for integrating 3D text with 3D content are inefficient, as they lack accurate control over text placement depth, rely on ancillary depth information that may not be available, and cannot adjust text placement in real-time or post-production without disrupting the 3D viewing experience.
Innovation Solution
The method determines parallax information from 3D content and uses it to position text accurately, allowing for real-time or offline adjustment based on user requirements, ensuring optimal placement without obstructing the 3D effect.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If 2D text information is used with 3D content, then text can be displayed, but accurate control over text placement depth is not achieved
Solution Approach 1:
The patent applies parameter changes by converting 2D text placement into 3D space using parallax information. The system extracts parallax values from corresponding features in left and right 3D views and uses these parameters to calculate appropriate text positions in both views, enabling precise depth control through mathematical transformation rather than direct manual positioning.
Solution Approach 2:
The patent introduces parallax information as an intermediary element between the 2D text and the 3D content. By extracting parallax values from existing 3D content features and using these as reference parameters, the system mediates the placement process to achieve accurate depth alignment without requiring direct depth map input or complex manual adjustment.
2Ease of operation
If 3D text is placed at a fixed depth for all frames, then text placement is simplified, but text may appear behind content scene and viewing comfort is reduced
Solution Approach 1:
The patent applies dynamics by making text placement adaptive rather than fixed. The system dynamically calculates text positions for each frame based on extracted parallax information from corresponding features, allowing text to move appropriately across frames while maintaining consistent depth relationships. This dynamic approach ensures text remains viewable and comfortable across varying content depths.
3Measurement precision
If depth information is captured from 3D content, then accurate text placement is possible, but depth information may not be available or difficult to compute
Solution Approach 1:
The patent applies self-service by having the 3D content itself provide the depth information needed for text placement. Instead of requiring external depth maps or additional capture equipment, the system extracts parallax information directly from the existing 3D content's left and right views. The content serves its own depth measurement function, eliminating the need for separate depth information sources.
4Reliability
If text placement is adjusted for each frame to maintain viewing comfort, then viewing experience is improved, but processing time increases
Solution Approach 1:
The patent applies preliminary action by extracting and storing parallax information from 3D content features in advance. This pre-computed parallax data is then reused for text placement calculations across multiple frames, avoiding redundant depth analysis for each individual frame. The preliminary extraction of parallax parameters significantly reduces per-frame processing time while maintaining accurate text positioning.

Function Achieved in This Case
This approach enables precise and flexible placement of 3D text, improving the viewing experience by maintaining accurate depth alignment and allowing for adjustments during or after content creation, independent of ancillary depth information.

AI summary
A method and system are defined for best positioning text in a 3D manner into associated 3D content by determining parallax information from the 3D content and by using such parallax information together with one or more requirements supplied by a user or producer for best positioning text in a 3D manner into associated 3D content. The determination of text position can be performed in real-time on the arriving image content stream as an on-line operation or in a non-real time mode on the entirety of the image content as an off-line operation.
