摘要 為有效了解地表資訊,可視研究目的而利用各種遙測方法獲取地面影像,但不論目前常用之飛機、或是以衛星為載具之空中攝影測量等相關研究,在影像獲取方面,常面臨成本費用、機動性、比例尺需求、後續影像處理等問題。因此,本研究選定一小流域面積之河川作為實驗區,並設計以氣球為載具之航空攝影方式,裝載CCD攝影機以及數位攝影機,透過CCD攝影機,即時無線傳輸地面影像至置於地面之監視螢幕,依此調整氣球至預定之位置後,遙控啟動數位攝影機之快門裝置。由成果影像中檢核點之精度結果,以及套疊正射糾正並鑲嵌後之河道影像與地形圖之成果,證明氣球載具之數值航空攝影方式,確可有效應用於大比例尺製圖之研究;本研究又利用分類後比較法( Post-classification comparison method)以偵測出溪流實驗區三個不同時期之變遷情況。
Satellite images have been applied in detecting the changes of an overall drainage basin. However, the resolution of the image data is not high enough for studying a small flood area. This research is therefore, going to collect images by using the low altitude remote sensing approach. A balloon was used as the platform to acquire image data in this research. A video camera and a digital camera were fixed together and hanged by the balloon. Radio images were communicated and displayed on a LCD monitor arranged on the ground. Once monitor the area of interest shown on the LCD, images were taken remotely with the digital camera. The resultant images were rectified for comparison and analysis. This method can be an effective and convenient way for the relative research about large-scale mapping.
