Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Generating 3D models of changing environments is challenging, particularly in terms of cost-effectiveness and time efficiency, as existing methods struggle to provide real-time or near-real-time decision-making capabilities without being prohibitively expensive or complex.
Innovation Solution
The system employs cameras with segment creator and shape condenser circuitry to passively capture and segment images, using probabilistic and stochastic approaches to differentiate between dynamic and static objects, and a server with model manager circuitry to compute hierarchical intersections of density quads, enabling efficient 3D model generation and transmission.

Engineering Contradiction Analysis
1Measurement precision
If existing methods are used to generate 3D models of changing environments, then measurement precision and contextual information are improved, but device complexity and cost increase significantly
Solution Approach 1:
The patent segments the environment into static and dynamic components by processing images from multiple cameras at different time points. By comparing temporal changes in image data, the system identifies moving objects and separates them from the static background, enabling accurate 3D modeling of dynamic environments without requiring complex specialized hardware for each component
Solution Approach 2:
The system uses standard cameras with added circuitry to perform multiple functions: capturing images, segmenting dynamic objects, and generating 3D models. The same camera infrastructure serves both static scene capture and dynamic object tracking, reducing overall system complexity while maintaining measurement precision
2Productivity
If existing methods are used to generate 3D models in real-time, then productivity and response time are improved, but device complexity and cost increase prohibitively
Solution Approach 1:
The system performs preliminary actions by capturing multiple images at different time points before generating the final 3D model. The cameras continuously capture image data that is then processed to identify dynamic objects, allowing real-time modeling without requiring complex real-time processing hardware by preparing data in advance
Solution Approach 2:
The system uses multiple cameras to capture copies of the environment from different perspectives and time points. These image copies are then processed and combined to generate the 3D model, enabling real-time productivity through parallel data collection rather than sequential complex processing
3Loss of information
If comprehensive environmental monitoring is implemented, then information completeness is improved, but loss of time and processing overhead increase
Solution Approach 1:
The system implements periodic action by capturing images at discrete time intervals rather than continuous monitoring. This periodic sampling captures sufficient environmental information to identify dynamic objects and generate accurate 3D models while minimizing processing time and computational overhead compared to continuous comprehensive monitoring

AI summary
Example systems, apparatus, articles of manufacture, and methods to model volumetric representations of objects in scenes are disclosed. Example apparatus disclosed herein are to form a set of polycells from image data of a scene, a first one of the polycells based on an intersection of (a) a first polytope representative of at least a portion of a first view frustrum corresponding to a first camera, and (b) a second polytope representative of at least a portion of a second view frustrum corresponding to a second camera. Disclosed example apparatus is also to determine a probability that the first one of the polycells is at least partially within an object in the scene, and based on comparison of the probability to a threshold, remove the first one of the polycells from the set of polycells to determine an updated set of polycells that model the object.
