摘要: | 光學高解析度遙測影像獲得日趨容易且被廣泛運用,如科學研究、土地植被分析、天災防治、都市計劃更新、軍事監測、交通、海洋及學術等領域均運用頻繁,使遙測影像產量越來越大,影像資訊交換更日趨頻繁。遙測影像處理技術儼然成為當前熱門新知,世界各一流學術及國家級研究機構均積極研發,各國廠商亦競相參與,創造許多影像新技術,並帶動了無限的商機,但衛星影像經由衛星拍攝後,需要經過一連串的處理,如:幅射校正、地理校正、高低解析度影像融合、色差校正、材質分析、特徵擷取及目標物偵測等重要的步驟,才能讓影像產品得以廣泛應用。其中因衛星影像均有尺寸限制,每幅影像色彩可能因拍攝時間、地點、角度或不同衛星感測器…等均不相同,要使影像色彩一致,融合及色差校正技術十分重要。 本文主要運用不同高低解析度影像,以新的色差校正流程(Color Adjustment Flow)改善影像色差問題,結合多種不同衛星感測器所拍攝的影像,形成一張色彩一致的新影像,不但可增加遙測影像判釋能力及範圍,並可擴大衛星影像運用範疇。 Optics high to analyze degrees of telemetering measurement image win becoming easy and use extensively, if scientific research , land vegetation analysis , natural disaster are prevented and cured, such fields as the city plans upgrading , military affairs monitoring , traffic , ocean and academy are used frequently, making the telemetering measurement image greater and greater in output, image information exchanges more frequent day by day. The image treatment technology of telemetering measurement becomes present hot new knowledge solemnly, every world first-class academy and national-level research institution research and develop actively , the manufacturers of various countries also competitively participate in , create a lot of image new technologies , and has driven the limitless business opportunity, but the image of the satellite needs passing a succession of treatment via after the satellite shoots , for instance: One penetrates correcting , geography correcting , level and analyzes one degree of images and merges, the colour difference is corrected, material analysis , characteristic pick fetching and such important steps as the goal thing is detected and examined, could let the image products must use extensive application . Among them because the image of the satellite has size that is limited , each image color may shoot time , place , angle or not with the satellite detecting device ?­,etc. the the same,it want it make because image the unanimous in color, not merge and colour difference getting more important very to correct technology. |
