Cleaning Robot Bumper Lighting for Low-Light Camera 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
Incorporating an illuminator positioned to increase light intensity within the camera's recognition area, ensuring the camera can capture images effectively even in low ambient light conditions, while also protecting the camera and illuminator from external damage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If a camera is provided for object recognition and navigation, then the cleaning apparatus can perform intelligent functions, but the camera cannot collect clear images due to insufficient light in low ambient light conditions
Solution Approach 1:
The illuminator is activated before the camera captures images to ensure the recognition area is sufficiently lit. This preliminary lighting action enables the camera to collect clear images even in low ambient light conditions, resolving the contradiction between image quality and ambient light intensity
Solution Approach 2:
The illuminator serves as an intermediary element between the environment and the camera. It provides additional light to the recognition area, mediating the insufficient ambient light to enable clear image capture by the camera
2Adaptability or versatility
If the camera and illuminator are oriented outside the device body for environmental sensing, then object recognition function is enabled, but the components are vulnerable to external damage
Solution Approach 1:
A transparent protective cover is used to protect the camera and illuminator while allowing light to pass through. This thin film structure enables the components to remain exposed for environmental sensing while providing protection against external damage
Solution Approach 2:
The camera and illuminator are nested within the device body structure, with openings provided in the bumper for light transmission. This nesting arrangement protects the components while maintaining their sensing functionality
3Measurement precision
If the illuminator is positioned to illuminate the camera's recognition area, then image capture quality improves, but the device structure becomes more complex
Solution Approach 1:
The illuminator and camera are integrated into a unified mounting structure on the device body. This merging of components simplifies the overall structure while maintaining the functionality of both elements for improved image capture
