    摘要:

    結合高光譜圖像處理和光譜分析方法,通過一次圖像掃描同時對蘋果的表面摔傷和糖分含量進行檢測,。蘋果第一主成分圖像與794nm的圖像相減后進行去噪和閾值分割處理,,摔傷檢測的準確率為92.6%,。對感興趣區(qū)域的反射光譜曲線進行多元散射校正,、一階導數(shù)和SG平滑處理后利用偏最小二乘回歸方法建立糖分含量的預測模型,,校正集相關系數(shù)Rc為0.93,,SEC為0.47°Brix,,驗證集相關系數(shù)Rv為0.92,SEV 為0.67°Brix,。結果表明:利用高光譜成像技術可以實現(xiàn)蘋果內部品質和外部品質的同時檢測,。

    Abstract:

    The hyperspectral imaging technology was used to detect the bruises and solid soluble content (SSC) of apples simultaneously. The image at 794nm from the first principle component was subtracted, the series of denoising and threshold processing were performed and the bruises on apples were predicted with the accuracy of 92.6%. In the hyperspectral imaging, region of interest (ROI) was determined and spectrum reference curve was calculated. The original reflectance spectrum curve was processed by multiplicative scatter correction (MSC), a first derivative and Savitzky-Golay (SG) smoothing, and PLSR model was developed to predict SSC with Rc of 0.93, SEC of 0.47°Brix, and Rv of 0.92, SEV of 0.67°Brix. The research showed that it was feasible to detect the SSC and bruises on apples simultaneously with hyperspectral imaging technology.
