第五章 結論與建議

5.2 建議

1. 本研究於多光譜病害分析時,時常遇到因為葉片蜷曲或是葉片互相遮蓋而造 成陰影的產生,利用釣魚線固定葉片的方法需要被改善成更能夠壓平葉片的 方式,手持式裝置部分也應該補足壓平葉片的機構

2. 本研究所利用之拍攝影像尺寸僅有 640 × 480 像素,若能有解析度更高的微 型相機將能夠使拍攝的準確率大幅提升,此外,濾鏡方面的頻寬如果能夠更狹 窄就能夠提高該波長對整體影像的貢獻度。

3. 因拍攝的方式為將草莓葉片放置於培養皿內,為防止葉片枯萎,需要定期加水 保持濕潤,如此一來培養皿內的濕度偏高,會造成炭疽病的顏色變淡,影響拍 攝結果,因此接下來的實驗應在植物為活體的狀況進行拍攝,會更符合實際的 發病狀況。

4. 多光譜的應用可朝向其他觀測對象發展,不同特徵波段下的特徵值可以協助 我們辨識的更精準,手持式裝置經過開模加工製作則可以將體積與重量減至 最小,有助於使用者攜帶使用。

5. 葉片陰影與病徵的辨識方法,可以再進行更多不同面向的組合,未來可望建立 一個植被陰影指標。
