3D Image Annotation Depth Adjustment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Displaying annotations on three-dimensional (3D) images is challenging due to the difficulty in recognizing points indicated by indicators, as the sense of depth is not clear, making it hard for users to distinguish between annotations and the 3D image.
Innovation Solution
A method and apparatus that determine and adjust the image depth of annotations and indicators based on the difference between the displayed annotation depth and the corresponding point depth, ensuring that annotations and indicators are displayed at a consistent depth, allowing users to clearly recognize the points, even when the image is rotated, enlarged, or moved.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If annotations are displayed on 3D images without depth adjustment, then the annotations can be shown on the image, but the sense of depth is not clear and users cannot distinguish between annotations and the 3D image
Solution Approach 1:
The patent adjusts the depth parameter of annotations dynamically based on the depth of corresponding 3D image points. By changing the depth parameter Z according to the formula Z = Z_annotation + k × (Z_point - Z_annotation), the annotation's depth position is modified to match the underlying 3D structure, creating clear depth differentiation and improving user recognition of annotation points.
2Adaptability or versatility
If the image is rotated, enlarged, or moved, then the image can be manipulated for better viewing, but the annotation depth consistency is lost making points harder to recognize
Solution Approach 1:
The system continuously monitors the depth relationship between annotations and corresponding 3D image points during image manipulation operations. When the image is rotated, enlarged, or moved, the patent recalculates and adjusts annotation depths in real-time based on the updated point depths, ensuring consistent depth alignment is maintained throughout the manipulation process.
Solution Approach 2:
The annotation depth adjustment is implemented as a dynamic process that automatically adapts to changes in image state. The patent establishes a dynamic relationship where annotation depths are continuously updated based on current point depths, allowing the system to maintain reliability during various image manipulation operations without requiring manual reconfiguration.

AI summary
A method of displaying a three-dimensional (3D) image by using a display apparatus includes generating an annotation related to a point of the 3D image and determining an image depth of the annotation, and displaying the annotation with the 3D image based on the image depth of the annotation, in which the annotation comprises at least one point or area of the 3D image.
