Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
3D models generated from images may inaccurately represent transient or mobile objects, leading to undesirable inaccuracies when viewed at a different time.
Innovation Solution
A system that includes a processor, camera, and storage, capable of generating a 3D model and associating objects with time-related metadata to identify and differentiate transient or mobile objects, allowing for selective representation in the model based on user input.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If a 3D model is generated from images taken at a previous time, then the model captures the state of objects at that time, but transient or mobile objects may be inaccurately represented when viewed at a different time
Solution Approach 1:
The system performs preliminary actions by capturing images at multiple time points before generating the 3D model. This allows the system to pre-identify transient and mobile objects by comparing temporal changes, and pre-associate them with time-related metadata before the model is viewed, ensuring accurate temporal context is preserved
Solution Approach 2:
Time-related metadata serves as an intermediary between the 3D model and the viewer. This metadata includes temporal information about when objects were captured and their mobility status, allowing the system to convey temporal context without requiring the viewer to be present at the original capture time
2Adaptability or versatility
If all objects are included in the 3D model, then the model is comprehensive, but transient objects reduce the model's accuracy when viewed at a different time
Solution Approach 1:
The system applies local quality by differentiating objects based on their temporal characteristics. Transient and mobile objects are identified and tagged with specific metadata indicating their temporary nature, allowing them to be treated differently from permanent objects in the model, thus maintaining both completeness and reliability
Solution Approach 2:
The system introduces dynamics by making the 3D model adaptable to different temporal contexts. Users can dynamically filter or adjust the display of transient objects based on their needs, allowing the model to transition between showing all objects and showing only permanent objects

AI summary
In one aspect, a device includes a processor, a camera accessible to the processor, and storage accessible to the processor. The storage bears instructions executable by the processor to receive data from the camera, establish a three-dimensional (3D) model of at least a portion of a location based at least in part on the data from the camera, identify at least one object at the location from the data from the camera, and associate the at least one object with time-related metadata.
