In 2022, we conducted experiments on Minamidaito Island in Okinawa, Japan during the growth or ripening stage of sugarcane (October-December 2022). We measured sugar quality and absorbance spectra of sugarcane stalks in the sugarcane field using a portable Vis-NIR spectrometer. Additionally, we collected multispectral images of sugarcane leaves using an unmanned aerial vehicle equipped with a multispectral camera. We evaluated the effectiveness of the multispectral images in estimating sugar quality by checking the correlation between sugar quality measured by the portable Vis-NIR spectrometer and vegetation indices.Furthermore, we investigated the effect of sugarcane skin on Minamidaito (Jan-Mar 2023). We scanned normal sugarcane stalks and peeled sugarcane stalks from different fields and varieties, then harvested the sugarcane and brought it back to the laboratory to measure sugar quality and develop a new calibration model. After developing models using the multiple linear regression method, we found that the peeled sugarcane spectra showed lower noise than the non-peeled spectra, which had higher noise caused by sugarcane wax. The results reveal that the peeled spectra model provides more accurate results than the non-peeled sugarcane spectra model, as the top two wavelengths with the highest correlation coefficient of the peeled sugarcane spectra model contain the sugar content absorption band (900-910 nanometers), whereas the normal sugarcane stalk spectra model had to select at least four wavelengths to find the sugar content absorption band.

2022年，我们在日本冲绳南北岛甘蔗生长成熟期(2022年10月至12月)进行了试验。利用便携式可见光-近红外光谱仪对甘蔗田蔗秆的糖分品质和吸收光谱进行了测定。此外，我们使用配备了多光谱相机的无人机收集了甘蔗叶片的多光谱图像。通过检验便携式可见光-近红外光谱仪测量的糖分质量与植被指标之间的相关性，评价了多光谱图像在评估糖分质量方面的有效性。此外，我们还研究了甘蔗皮对南北道(2023年1-3月)的影响。我们扫描了正常的甘蔗茎，并对不同田地和不同品种的甘蔗进行了剥离，然后收获了甘蔗，并将其带回实验室进行糖分质量测量，并开发了新的校准模型。用多元线性回归方法建立模型后发现，去皮的甘蔗光谱比未去皮的去皮光谱具有更低的噪声，而去皮的甘蔗光谱有更高的甘蔗蜡噪声。结果表明，去皮甘蔗光谱模型比未去皮甘蔗光谱模型提供了更准确的结果，因为去皮甘蔗光谱模型中相关系数最高的两个波长包含含糖量吸收带(900-910纳米)，而普通甘蔗茎光谱模型必须选择至少四个波长才能找到含糖量吸收带。
