Spatially Aligned AR Display for Real-World Target Recognition
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing surveillance systems, such as described in Patent Literature 1, do not effectively integrate real-space and virtual-space imagery, making it difficult for surveillants to recognize the position of surveillance targets in real space, thereby reducing the efficiency of on-site operations.
Innovation Solution
An information display system that acquires position information of a display device and an imaging device, aligns the captured image with the display device, and generates a virtual image to be superimposed on the real-space image, using techniques like 3D sensors and head-mounted displays to enhance spatial recognition.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If a head-mounted display system displays only detection results without spatial alignment, then the system structure remains simple, but the surveillant cannot recognize the position of surveillance targets in real space images
Solution Approach 1:
The patent merges the real space image captured by the imaging device with the virtual image containing detection results through spatial alignment. The position information of both the display device and imaging device is used to align the virtual image with the real space image, allowing the surveillant to see both the actual environment and detection results in their correct spatial positions simultaneously.
Solution Approach 2:
The patent introduces position information as an intermediary element that mediates between the imaging device and display device. By acquiring and utilizing position information from both devices, the system aligns the virtual image with the real space image, enabling accurate spatial position recognition without requiring direct physical connection between devices.
2Productivity
If the system displays detection results without aligning with real space positions, then the processing complexity is reduced, but the surveillance operation efficiency cannot be increased
Solution Approach 1:
The system combines the real space image and virtual image with proper spatial alignment, allowing the surveillant to recognize target positions directly in the real space context. This merging of aligned images eliminates the need for separate analysis of detection results and real space images, thereby improving surveillance operation efficiency.
Solution Approach 2:
The patent superimposes the two-dimensional virtual image containing detection results onto the real space image in a way that preserves spatial relationships. By displaying the virtual image in alignment with the real space positions rather than as a separate overlay, the system adds spatial contextualization to the detection information.
3Measurement precision
If position alignment between imaging device and display device is implemented, then spatial recognition is improved, but the system requires more complex position information processing
Solution Approach 1:
The patent uses position information as an intermediary to achieve alignment between the imaging device and display device. By acquiring position information from both devices and using it to align the virtual image with the real space image, the system achieves precise spatial positioning without requiring complex direct coordination between devices.

AI summary
An information display system of the present disclosure includes: an acquiring unit that acquires position information of a display device displaying a real space image, an imaging device capturing an image of a predetermined target object, and the target object within a captured image captured by the imaging device; an aligning unit that makes a position of the target object within the captured image correspond to a position of the display device based on the position information; a generating unit that generates a virtual image of the target object based on the position information of the target object; and a display control unit that controls the display device to display the virtual image of the target object made to correspond to the position of the display device so as to be superimposed on the real space image.
