Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing systems face challenges in reliably detecting and tracking targets in real-time due to processing speed limitations and communication delays, leading to potential loss of target visibility when the target moves out of the camera's view or changes direction.
Innovation Solution
An irradiation system comprising a server device that processes image data to generate lightweight tracking data and transmits it to a terminal device, which then irradiates the target with marking light based on this data, allowing for real-time target detection and tracking.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If authentication processing is performed on the wearable device, then detection accuracy is improved, but processing speed deteriorates due to insufficient arithmetic device performance
Solution Approach 1:
The system divides authentication processing into two segments: complex authentication processing is performed on a server device with high computational power, while the wearable terminal device only performs lightweight tracking and marking operations. This segmentation allows accurate authentication without overburdening the limited arithmetic device of the wearable device.
Solution Approach 2:
A server device is introduced as an intermediary between the wearable terminal device and the authentication system. The server receives image data from the terminal, performs comprehensive authentication processing, and returns tracking information to the terminal, enabling accurate detection without requiring the terminal to perform heavy authentication calculations locally.
2Power
If image data is transmitted to a server for processing, then processing capability is improved, but real-time response deteriorates due to communication delay
Solution Approach 1:
The system extracts only the essential tracking information (position coordinates and movement direction) from the full image data after server processing. By transmitting only this extracted tracking information back to the terminal device rather than the entire processed image data, communication time is significantly reduced while maintaining real-time tracking capability.
Solution Approach 2:
The server performs authentication processing in advance on captured image data before the terminal device needs to display or act on the information. This preliminary processing allows the terminal to receive pre-processed tracking information quickly, reducing the perceived delay for real-time tracking operations.
3Reliability
If tracking processing is performed on every frame, then tracking reliability is improved, but data processing load increases
Solution Approach 1:
Instead of performing comprehensive authentication processing on every frame, the system implements periodic processing where the server performs authentication on selected key frames while the terminal performs continuous but simpler tracking between these key frames. This periodic approach maintains tracking reliability while significantly reducing overall data processing load.

AI summary
Provided is an irradiation system for reliably detecting a desired detection target and precisely irradiating marking light on the detected detection target. The irradiation system includes: a server device detecting, by authentication processing, a detection target from image data capturing a monitored area, generating, from each piece of a plurality of pieces of image data captured in a time span including a capture time of image data in which the detection target is detected, lightweight data obtained by lightening an amount of data in the plurality of pieces of image data, and transmitting tracking data obtained by aggregating a plurality of pieces of generated lightweight data; and a terminal device capturing the monitored area and outputting image data, transmitting the captured image data to the server device and also receiving the tracking data from the server device, and irradiating light on the detection target, based on the received tracking data.
