Investigation Support Device Using Omnidirectional Imaging
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Investigations are limited by the investigator's viewing angle, preventing the capture and analysis of information outside this range, which can lead to incomplete data and reduced accuracy.
Innovation Solution
An investigation support device equipped with an omnidirectional camera and a tablet that captures and processes both front and back imaging data, along with audio, to provide comprehensive investigation results and identify positions, enhancing data collection and accuracy.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If an investigator conducts investigation using only their viewing angle, then the operation is simple, but the investigation accuracy deteriorates because information outside the viewing angle cannot be captured
Solution Approach 1:
The patent introduces a camera as an intermediary device that captures images from multiple positions (front and back of the investigator) to provide information that would otherwise be unavailable to the investigator. This mediator enables comprehensive data collection without complicating the investigator's operation, as the system automatically processes and associates the multi-position images with the investigation results.
Solution Approach 2:
The patent adds a spatial dimension to the investigation by capturing images not only from the investigator's direct viewing angle but also from front and back positions. This multi-dimensional approach ensures that information outside the original viewing angle is captured, thereby improving investigation accuracy without requiring the investigator to manually reposition or adjust their viewpoint.
2Measurement precision
If multi-position imaging is implemented to capture out-of-viewing-angle information, then the investigation accuracy improves, but the device complexity increases
Solution Approach 1:
The imaging system is segmented into multiple independent camera units positioned at different locations (front and back of the investigator). Each camera independently captures images from its specific position, and the system associates these segmented image data sets with the corresponding investigation results. This segmentation approach improves accuracy by capturing comprehensive spatial information while managing complexity through modular, independent camera units.
3Loss of information
If comprehensive data including out-of-viewing-angle information is collected, then the investigation completeness improves, but the data processing complexity increases
Solution Approach 1:
The system implements feedback by automatically associating multi-position image data with investigation results and providing this integrated information back to the investigator. This feedback mechanism ensures that no information is lost during data collection, as the system systematically links front and back images with the corresponding investigation findings, enabling comprehensive analysis without manual data correlation.

AI summary
An investigation support device executes first acquisition processing of acquiring an investigation result including at least one of text data, imaging data, and audio data in investigation at an investigation date and time, second acquisition processing of acquiring first imaging data imaged from a front of an investigator at the investigation date and time and second imaging data imaged from a back of the investigator at the investigation date and time, identification processing of identifying an investigation position at the investigation date and time based on at least one of the first imaging data and the second imaging data acquired by the second acquisition processing, and association processing of associating the investigation result acquired by the first acquisition processing, the second imaging data, and the investigation position identified by the identification processing with the investigation date and time.
