Virtual Environment Image Composition for Perceived Photorealism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for creating virtual environments fail to provide photorealistic representations of objects within virtual spaces while minimizing computational and design costs, especially in web applications, as they either require complex 3D modeling or 360° photography, which are either too costly or limit flexibility and realism.
Innovation Solution
A method that achieves perceived photorealism by approximating physical laws of physics, allowing for the creation and dynamic insertion of objects into virtual environments, optimizing computation and design time, and maintaining image quality.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If 3D modeling is used to create virtual environments, then photorealistic rendering quality is improved, but computation time and design cost increase significantly
Solution Approach 1:
The patent segments the virtual environment into a background image (captured via 360° photography) and separate virtual objects (products, shelves, etc.). This segmentation allows the background to be pre-captured with high photorealism while objects can be independently rendered and inserted, reducing overall computation time and design cost.
Solution Approach 2:
The patent performs preliminary action by capturing the background environment through 360° photography before inserting virtual objects. This pre-captured background serves as a photorealistic foundation, eliminating the need for time-consuming 3D modeling of the entire environment and allowing rapid insertion of virtual objects later.
2Productivity
If 360° photography is used to create virtual environments, then computation cost is reduced, but flexibility to modify and insert objects is lost
Solution Approach 1:
The patent segments the final image into a photorealistic background (from 360° photography) and separate virtual objects. This segmentation enables the background to be captured efficiently via photography while objects remain independent, editable elements that can be freely inserted, moved, or modified without re-capturing the entire scene.
Solution Approach 2:
The patent introduces an intermediary layer - virtual objects with associated metadata (position, orientation, scale) - that mediates between the static 360° background and the need for dynamic object insertion. This intermediary structure allows objects to be inserted into predefined locations in the background, combining the efficiency of photography with the flexibility of 3D object manipulation.
3Ease of operation
If virtual objects are inserted into 360° environments using standardized parameters, then ease of insertion is improved, but photorealism and psychological impact are degraded
Solution Approach 1:
The patent applies local quality by allowing different levels of detail and customization for different objects and locations. While insertion uses simplified parameters (position, orientation, scale), each object can have its own photorealistic textures, lighting properties, and shadows tailored to its specific location in the background, enhancing overall photorealism without complicating the insertion process.
Solution Approach 2:
The patent uses parameter changes to enhance photorealism after insertion. Objects can have their position, orientation, scale, lighting, and shadow parameters adjusted based on their specific location in the 360° background. This allows standardized insertion procedures to be followed while still achieving location-specific photorealistic effects that enhance psychological impact.

AI summary
A method of construction of a computer-generated image, the computer- generated image comprising a representation of an environment, called setting image, from a point of view, and at least one location of the setting for insertion of an image of an object, comprises: - a step of creating of a setting image applying the laws of perspective, - a step of generating at least one rendered or captured image of at least one object, the representation of the object in each image obeying the laws of perspective during the generation of the object image, the generating step being independent from the creating step, - a step of incorporation of the object image into at least one location of the setting image, wherein the application of the laws of perspective on the object image creates an error, discernible to the human eye, with the law of perspective applied in the point of view, whereby the constructed computer-generated image presents an overall perceived photorealism.
