3D Model Rendering via Binary Mask Simplification
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Online shoppers often receive items that do not match their expectations due to differences in size and style when viewed in person for the first time, as photographs cannot accurately represent the object's dimensions and surroundings.
Innovation Solution
A virtual image capture system generates simplified three-dimensional representations of objects using CAD files, capturing multiple views from a hemisphere and converting them into binary masks to create an object mesh structure, optimized for mobile devices, which can be overlaid with virtual images to provide a photorealistic representation in augmented reality.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If a complex three-dimensional virtual representation of an object is rendered based on a CAD file, then the representation includes detailed information about the object, but the representation is not optimized for mobile viewing due to the amount of information represented
Solution Approach 1:
The patent extracts only the essential visual information needed for mobile viewing by capturing virtual images from a hemisphere of views around the object and using binary masks to represent only the visible object portions. This extracts the necessary visual data while removing unnecessary complex geometric information, resolving the contradiction between information completeness and mobile device complexity.
Solution Approach 2:
The patent creates simplified copies of the complex 3D object by generating 2D binary mask images from multiple viewing angles. These binary mask copies retain the essential visual representation of the object from different perspectives while being significantly simpler than the original complex 3D model, enabling efficient mobile rendering without losing critical visual information.
2Loss of information
If photographs are used to display objects online, then the objects can be viewed, but the photographs cannot accurately represent the object's dimensions and surroundings
Solution Approach 1:
The patent transitions from 2D photographs to a multi-dimensional virtual viewing system by capturing images from a hemisphere of views around the 3D object. This allows users to explore the object from multiple angles and perspectives, accurately perceiving dimensions and spatial relationships that cannot be conveyed by single static photographs, while still rendering manageable 2D images on mobile devices.
Solution Approach 2:
The patent creates a universal viewing system that works across multiple device types and viewing conditions. The binary mask images generated from the hemisphere of views can be displayed on any device screen size and adapted to different viewing contexts, providing consistent accurate dimensional representation regardless of the specific display device used.

AI summary
A complex three-dimensional virtual representation of an object can be rendered. Virtual images can be captured representing a plurality of views of the complex virtual representation. The virtual images can be converted into binary masks depicting the object pixels and non-object pixels in the virtual images. The binary masks can be used to create a three-dimensional representation of the object having lower complexity than the first three-dimensional virtual representation of the object. In embodiments, the low complexity three-dimensional virtual representation of the object and the virtual images are sent to a mobile device to render a low payload representation of the object on the mobile device.
