Image Difference Display Using Position and Orientation Matching
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing image display systems struggle to quickly and accurately show images corresponding to a specific location, making it difficult to detect suspicious objects in security scenarios where personnel changes frequently, as they cannot efficiently match images captured from different directions at the same location.
Innovation Solution
An image display system that utilizes a mobile terminal and server to acquire and display images based on both position and orientation, allowing for the detection of differences between current and past images captured at similar orientations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If images are retrieved based only on position information, then the system can display images from captured places, but it cannot efficiently identify the specific image corresponding to a particular place among multiple images captured from the same position
Solution Approach 1:
The patent adds orientation information as a second dimension to the image retrieval system. Instead of storing only position information (one dimension), the system now stores both position and orientation information (two dimensions), enabling precise identification of specific images captured from particular directions at captured places, thereby resolving the ambiguity of selecting one image among multiple images from the same position
2Reliability
If multiple personnel perform surveys at different times, then comprehensive security coverage is achieved, but it becomes difficult to communicate and compare findings between different survey teams
Solution Approach 1:
The patent uses image data as a visual copy of the surveyed environment. By capturing and storing images with position and orientation information, each survey team creates a visual record that can be directly compared with other teams' findings. The system displays current images alongside historical images, enabling personnel to visually compare survey results without relying on subjective descriptions, thus preserving and communicating survey findings accurately across different teams
3Quantity of substance
If the system stores and provides many images captured in prior surveys, then comprehensive security data is available, but searching through multiple images to find the specific one showing a particular place becomes time-consuming
Solution Approach 1:
The patent implements a feedback mechanism where the system automatically compares current survey images with stored historical images using position and orientation information. When a new image is captured, the system retrieves the corresponding historical image based on matching position and orientation data, and displays both images together with highlighted differences. This automated feedback loop eliminates the need for manual searching through multiple images, significantly improving productivity while maintaining comprehensive image storage
