Solution Overview
Problem
Existing technologies face challenges in accurately detecting light emitters in indoor air conditioner units due to the lack of position and orientation information of the camera and map information of the location.
Innovation Solution
An area setting device is developed, which includes an air outlet detection unit to detect air outlets from image data and an area setting unit to set an area of interest based on the detected air outlets, thereby narrowing the detection area for the light emitter.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Difficulty of detecting and measuring
If image data is used to detect light emitters, then detection capability is provided, but detection accuracy deteriorates due to mistaken detection of objects with similar characteristics
Solution Approach 1:
The patent divides the image data processing into two stages: first detecting air outlets (which are larger and easier to detect), then using the air outlet positions to define an area of interest for light emitter detection. This segmentation allows the system to leverage the easier-to-detect air outlets to guide the more difficult light emitter detection, improving overall accuracy while maintaining detection capability.
Solution Approach 2:
The patent applies local quality by restricting light emitter detection to a specific area of interest defined by the air outlet positions. Instead of searching the entire image, the system focuses computational resources on the region where light emitters are likely to be located based on the detected air outlets. This localized approach reduces mistaken detection of objects with similar characteristics outside the area of interest.
2Measurement precision
If area restriction is applied to improve detection accuracy, then detection precision improves, but device complexity increases due to additional detection steps
Solution Approach 1:
The patent implements preliminary action by first detecting air outlets before attempting to detect light emitters. The air outlet detection creates a foundation (area of interest) that guides the subsequent light emitter detection. This preliminary step simplifies the overall process by pre-defining where to look for light emitters, reducing the complexity of the light emitter detection algorithm itself.
Solution Approach 2:
The patent uses air outlets as an intermediary element to bridge the gap between image capture and light emitter detection. Rather than directly detecting light emitters from the entire image, the system first detects air outlets (the intermediary) and then uses their positions to define the search area. This intermediary approach simplifies the detection process by breaking it into manageable steps with clear relationships between them.

AI summary
An image acquisition unit (21) acquires image data obtained by capturing an image of an indoor unit of an air conditioner. An air outlet detection unit (22) gives, as input, the image data of the indoor unit acquired by the image acquisition unit (21) to an object detection model to detect an air outlet. An area setting unit (23) sets an area of interest to be a range in which a detection target, such as a light emitter installed in the indoor unit or an identification number displayed on the indoor unit, is to be detected, based on a detected area of the air outlet detected by the air outlet detection unit (22).
