摘要

隨著自動化科技的進步，航測工業也自動化為主要發展方向。影像匹配技術用於自動化空中三角點之量測研究已有多年，但至今尚未用於實際立體測圖生產作業上。近年來雖有攝影測量工作站之出現，但尚難完全取代現廣泛使用的解析測圖儀。在可見的未來，航測製圖仍會以人工在解析測圖儀上作業，尚難完全自動化。雖然全自動化之空中三角測量尚無法實現，但是仍然可用部份由人工作業的半自動方式達到實用之目的。本文之目標即在發展一套可實用的半自動空中三角作業方法，以自動化影像匹配量取空中三角點以取代昂貴的轉點儀以及操作人員。同時著重在如何把人眼無法確認的空中三角點成果轉至解析製圖儀內，自動完成不需人工量測的絕對方位。以冀對整個航測自動化有所貢獻。

In recent years, automatic Photogrammetry becomes a major goal for everyone in the Photogrammetric industry. The technique of image processing has been used in aerial triangulation measurement for years, but it has not yet been put on production lines. Although digital photogrammetric workstations have been brought up to the market for some years, they still can not replace analytical plotters because of the limitations in there functions. Therefore mapping will still be done manually on the analytic plotters in the near future.Although fully automatic aerial triangulation measurement has not yet been realized, some kinds of semi-automatic solutions are still possible. In this paper we developed a method for semi-automatic aerial triangulation measurement. The major concern of this development is production, not sophisticated matching theories, i.e. to put the image matching technique actually on production lines to replace the expensive point transfer instruments and experienced operators so that it is not jmerely a research topic in the laboratory. We hope that the results of the semi-automatic aerial triangulation obtained here can contribute to the automation of Photogrammetry in the practice.
