Lighting Fixture Identification via Image-Based Light Emitter Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing systems for controlling lighting fixtures using information terminals require storing fixture positions in a server, which is burdensome and can lead to incorrect identification when fixtures are replaced or duplicated.
Innovation Solution
An information processing method that enables direct association of objects with illumination devices by transmitting control information, capturing images of light emitters, and recognizing objects based on image data without relying on server-stored positions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If lighting fixture positions are stored in a server, then the system can control lighting fixtures, but this places a heavy burden on the user and complicates the system
Solution Approach 1:
The patent extracts the position storage function from the server and relocates it to the terminal device. The terminal device now stores positions of illumination devices in its own storage unit, eliminating the need for users to manually input positions to a server and simplifying the overall system architecture.
Solution Approach 2:
The patent introduces an image recognition unit that acts as an intermediary between the camera and the illumination device identification. This unit automatically recognizes illumination devices in captured images and extracts their positions, replacing the need for manual server-based position storage and reducing user burden.
2Measurement precision
If lighting fixture positions are stored in a server, then the system can identify target fixtures, but when fixtures are replaced or duplicated, multiple fixtures at the same position cause incorrect identification
Solution Approach 1:
The patent performs preliminary actions by capturing an image of the illumination device before control operations. The image recognition unit recognizes the illumination device in the captured image and extracts its position, establishing accurate device-position mappings in advance to prevent misidentification when devices are replaced or duplicated.
Solution Approach 2:
The patent implements feedback by using the camera to capture images of illumination devices and the image recognition unit to verify device positions. This visual feedback mechanism ensures that the correct device is identified and controlled, even when multiple devices exist at similar positions or when devices are replaced.

AI summary
An information processing method includes: transmitting, by an information terminal paired with each of a first device including a first light emitter and a second device including a second light emitter, first information for controlling driving of the first light emitter to the first device, based on first identification information related to the first device; executing, by the first device, first control for controlling the driving of the first light emitter, based on the first information; acquiring, by the information terminal, first image data representing an image including a first object and a second object, the first image data being an image of the first light emitter and the second light emitter picked up after the execution of the first control; and associating, by the information terminal, the first object with the first device, based on the first image data and the first information.
