IKONOS

基本解釋

Bed on consistence in length and direction, this paper presents an approach to extract city road from IKONOS images.
基于長(zhǎng)度和方向一致性，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.
影像匹配是采用多重解析度區(qū)域影像匹配技術(shù)來(lái)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)得到地面點(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)星公司所提的立體像對(duì)，已經(jīng)經(jīng)過(guò)初步幾何改正成為準(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)融合為 1 m的多光譜數(shù)據(jù)會(huì)充分利用二者的信息 ,提高目視和自動(dòng)影像提取的類別精度。
