基于高光谱成像的水果损伤分析研究
|
摘要
高光谱成像技术包含图像信息和光谱信息。本文利用高光谱成像技术检测苹果摔伤,主要采用主成分分析、波段比算法和支持向量机分析所采集的高光谱图像数据。实验结果表明,波段比算法和主成分分析法分类识别正确率为93.3%,与支持向量机相比更适用于苹果摔伤的实时快速检测。
Hyper-spectral imaging technology includes image information and spectral information. This paper usedhyperspectral imaging technology to detect apple fall. In the process of experiment, principal component analysis,band ratio algorithm and support vector machine were used to analyze hyperspectral image data collected. The experi-mental results showed that the accuracy of band ratio algorithm and principal component analysis was 93. 3%, whichwas more suitable for real time and fast detection of apple fall than support vector machine.
