3D Model Navigation for Multi-Viewpoint Image Inspection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing techniques for navigating among multiple images of an object in three-dimensional space are inadequate, particularly in visual inspection environments where images are captured from disparate viewpoints, requiring improved methods to reconcile user input with suitable camera positions and angles for optimal viewing.
Innovation Solution
A method and system that utilize a three-dimensional model to navigate among images by displaying a first image, receiving user selection of a location, selecting a second image for improved view, rendering an animation of spatial transition using the three-dimensional model, and displaying the second image upon reaching the destination viewpoint, incorporating user input devices and computer-readable instructions for image selection and rendering.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If point-and-click interfaces with animated fly-overs are used for navigation, then user ability to select locations is improved, but user orientation and spatial understanding deteriorate
Solution Approach 1:
A three-dimensional model serves as an intermediary between the user and the collection of source images. The model provides continuous spatial context and orientation information, while the system automatically selects appropriate source images to display. This mediator resolves the contradiction by maintaining spatial understanding through the 3D model while enabling easy location selection through the interface.
2Adaptability or versatility
If arbitrary viewpoints are chosen in response to user input, then navigation flexibility is improved, but view quality and satisfaction deteriorate
Solution Approach 1:
The system incorporates feedback by evaluating multiple candidate source images based on quantitative criteria (viewing angle, distance, orientation) and selecting the image that best satisfies the user's location selection. This feedback mechanism ensures that while navigation remains flexible, the displayed views maintain high quality by automatically choosing the most appropriate source image from the collection.
3Quantity of substance
If multiple source images from disparate viewpoints are used, then visual information availability is improved, but navigation complexity increases
Solution Approach 1:
The system extracts and utilizes the three-dimensional geometric information from the collection of source images to build a 3D model. This extracted model serves as a simplified navigation interface, removing the complexity of managing multiple disparate images while preserving all visual information. Users navigate the 3D model rather than directly managing the complex image collection.

AI summary
A three-dimensional model of an object is employed to aid in navigation among a number of images of the object taken from various viewpoints. In general, an image of an object such as a digital photograph is displayed in a user interface or the like. When a user selects a point within the display that corresponds to a location on the surface of the object, another image may be identified that provides a better view of the object. In order to maintain user orientation to the subject matter while navigating to this destination viewpoint, the display may switch to a model view and a fly-over to the destination viewpoint may be animated using the model. When the destination viewpoint is reached, the display may return to an image view for further inspection, marking, or other manipulation by the user.
