Cartesian Camera Arm for Stable Hyperspectral Plant Imaging
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing systems for determining fruit and vegetable characteristics using hyperspectral imaging face challenges due to variable natural light spectra, which can cause errors in image processing and analysis, and often lack the capability to isolate specific portions of the fruit-bearing plant for verification and additional processing using AI models.
Innovation Solution
A mobile camera system with a cartesian arm that moves a hyperspectral camera along three axes, accompanied by a color or depth camera and a controlled light source, allowing for precise image capture and illumination, enabling accurate hyperspectral image analysis and AI-based processing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If natural light is used for hyperspectral imaging, then the system can operate without additional illumination equipment, but the variable spectra of natural light cause errors in image processing and analysis
Solution Approach 1:
The patent introduces a controlled light source as an intermediary between the object being imaged and the hyperspectral camera. This light source provides stable, known spectral illumination that mediates the interaction between light and the fruit/vegetable surface, eliminating the variability inherent in natural light while enabling accurate hyperspectral data acquisition.
2Loss of information
If only hyperspectral imaging is performed, then the system can capture detailed spectral data, but it becomes difficult to isolate specific plant portions for verification and AI processing
Solution Approach 1:
The patent employs multiple cameras (including visible spectrum cameras) to capture different types of image data simultaneously or sequentially. This segmentation of imaging functions allows the system to capture both comprehensive spectral information and specific visual data for portion isolation, enabling users to verify and process specific plant portions effectively while maintaining complete spectral data.
3Adaptability or versatility
If a mobile camera system with three-axis movement is implemented, then the system can locate and capture images of specific plant portions, but the device complexity increases
Solution Approach 1:
The cartesian arm structure serves multiple functions: it provides precise three-axis positioning of the camera system, supports various camera configurations, and enables both manual and automated operation modes. This multi-functionality justifies the increased structural complexity by delivering versatile positioning capabilities that adapt to different imaging requirements.
Data Source
AI summary
A mobile camera apparatus includes a cartesian arm that is able to move along three axes, a first camera to generate first image data, and a second camera to generate second image data and is attached to the cartesian arm. The cartesian arm is operable to move the second camera along the three axes, and the second image data includes hyperspectral image data.
