第二節建議

本研究的建議如下：

1. LPS 需要以人工方式量測控制點與連結點，但因 Optio A40 屬於非量測型像機，且 MD4-200 所能提供的外方位資訊精度較差，因此在 LPS 自動匹配特徵點的過程中若參考外方位參數，將產生大量的錯誤匹配點。此外，因 MD4-200 的航高較低、影像涵蓋範圍小，致使影像數量相當多，無論是人工選點或以人為方式剔除錯誤點位，皆須耗費相當時間，若能搭配匹配成功率高的影像匹配技術，則以自率光束法提升UAV 航拍影像的空三平差精度應可大幅提升。

2. MD4-200 的體型較小，且屬於 UAV 分類中的迷你型機種，受風的干擾較大，建議可採用動力較強、穩定性相似的其他機種執行航拍任務，

以取得品質更佳的影像。

3. 本研究中的各次測試，是將平差過程中所有影像的內方位參數視為相同，但由非量測型像機的內方位條件較不穩定、且本研究中各次自率光束法平差（含預改正的自率光束法平差）後所得的內方位參數並不相同，未來應用 UAV 搭載非量測型像機航拍時，可考慮使用動態的內方位參數描述。

4. 本研究中尚未探討控制點數量對空三平差結果的影響，然控制點數量是否應依不同的率定結果而調整、控制點的多寡是否將影響自率光束法空三平差的結果，在本研究中皆難以一併探討。若未來能使用較少的控制點數獲得精度相同的空三平差成果，則可提高 UAV 系統搭載非量測型像機航拍的效率。
