數位空載製圖相機

以大面積地形圖測製之目的而言，「空載製圖相機」是一種重要工具。無論是以航空攝影測量為製圖方法，或是運用空載光達獲得地形資料，在實際作業中，影像總是因能提供豐富資訊，而常常列入合約交付項目。近代攝影已脫離底片，大量使用光電感測器，因而完全進入數位時代。此外，隨同科技之演進與製圖標的內涵的逐步擴展，傾斜攝影亦逐步成為一種例行性之航空攝影作業方式。這些現象，均反映在「空載製圖相機」之發展。本文回顧目前市場上已發行而且目前可購置之「空載製圖相機」，計十家廠牌，二十四種機型，比較其主要指標如像元數、像移補償等，並分別描述其設計理念。 Aerial mapping camera is an important mapping tool. For large area topographic mapping, ortho-image is frequently included as one of the contract item, no matter whether the surveying isconducted with photogrammetry or airborne lidar. The reason of this is evident from the rich contentof image. After the application of film for several decades, digital sensors based on photoelectriceffect have replaced film. Besides, due to the expansion of mapping content, photograph with obliqueview is gradually becoming popular. All these are reflected in the development of aerial mappingcamera. This paper reviews aerial mapping cameras currently in the market, including 24 modelsfrom 10 manufacturers. The characteristic items such as pixel numbers, motion compensation, etc., are summarized, and also the design principle of the camera.
