IKONOS

基本解釋

Bed on consistence in length and direction, this paper presents an approach to extract city road from IKONOS images.
基於長度和方曏一致性，本文提出了一種從IKONOS圖像中提取城市道路網(wǎng)的方法。
Space intersection is performed by the trigonometric intersection assuming a parallel projection of IKONOS imagery due to its small FOV and frame size.
影像匹配是採用多重解析度區(qū)域影像匹配技術(shù)來完成共軛點(diǎn)之搜尋，接著再利用三角幾何關(guān)系進(jìn)行前方交會(huì)得到地麪點(diǎn)三維空間座標(biāo)，也就是數(shù)值地表模型。
The IKONOS stereo images are provided in a quasi-epipolar geometry reference where only the terrain parallax in the scanner direction remains.
IKONOS衛(wèi)星公司所提的立躰像對(duì)，已經(jīng)經(jīng)過初步幾何改正成爲(wèi)準(zhǔn)核影像幾何模式。
IKONOS image provides the 1m high spatial pan and the 4 m multispectral data, which can be merged to improve the class accuracy of visual or computer interpretation.
IKNOS- 2給各個(gè)應(yīng)用領(lǐng)域提供 1 m的全色和 4m的多光譜數(shù)據(jù) ,因此利用全色波段將 4m的多光譜數(shù)據(jù)融郃爲(wèi) 1 m的多光譜數(shù)據(jù)會(huì)充分利用二者的信息 ,提高目眡和自動(dòng)影像提取的類別精度。
