Cleaning Device Camera Illumination for Low-Light Image Recognition
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional cleaning apparatuses face issues with image recognition and navigation due to poor image collection by cameras, often resulting in unclear images, which affects their functionality and user experience.
Innovation Solution
The cleaning apparatus incorporates a camera and an illuminator mounted on the device body, with the illuminator positioned below the camera to enhance light intensity in the recognition area, ensuring clear image capture even in low ambient light conditions, and is protected from damage through strategic placement and design.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If the camera is mounted on the device body to perform object recognition and navigation, then the cleaning apparatus can perform intelligent functions, but the camera cannot collect clear images in low light conditions due to insufficient illumination
Solution Approach 1:
The illuminator is activated before the camera captures images to ensure the recognition area is sufficiently lit. This preliminary illumination action allows the camera to collect clear images even in low ambient light conditions, resolving the contradiction between image clarity and ambient light intensity
Solution Approach 2:
The illuminator acts as an intermediary element between the camera and the external environment. It provides additional light to the recognition area, enabling the camera to capture clear images without relying solely on ambient light, thus resolving the contradiction between image quality and lighting conditions
2Adaptability or versatility
If the camera and illuminator are mounted on the device body, then the apparatus can perform recognition functions, but the components are vulnerable to external damage
Solution Approach 1:
The camera and illuminator are nested within the device body structure, with the illuminator positioned below the camera. This nested arrangement allows the components to be protected by the device body while still performing their recognition functions, resolving the contradiction between adaptability and reliability
Solution Approach 2:
The device body structure provides beforehand cushioning and protection for the camera and illuminator. The components are strategically positioned and mounted to be protected from external damage while maintaining their functional capabilities, thus resolving the contradiction between recognition function and component protection
3Measurement precision
If the illuminator is positioned below the camera to enhance light intensity, then clear image capture is achieved, but the device structure becomes more complex
Solution Approach 1:
The camera and illuminator are merged into a single functional unit mounted on the device body, with the illuminator positioned directly below the camera. This combined arrangement achieves clear image capture through strategic positioning while minimizing structural complexity by integrating the components closely together
