以广西某地区新航摄遥感影像数据为例,利用已有1:10000 DOM 和 DEM,通过影像匹配获取并自动提取控制点,实现无需外业控制的空中三角测量。通过检测空三和 DOM 产品的平面和高程精度,表明该方法在保证精度可靠性的同时,极大提高了成图效率。
以廣西某地區新航攝遙感影像數據為例,利用已有1:10000 DOM 和 DEM,通過影像匹配穫取併自動提取控製點,實現無需外業控製的空中三角測量。通過檢測空三和 DOM 產品的平麵和高程精度,錶明該方法在保證精度可靠性的同時,極大提高瞭成圖效率。

Take new aerial remote sensing image data in somewhere of Guangxi as an example,using the existing 1 :10000 DOM and DEM,through image matching to obtain automatic control points,achieve the goal of aerial triangulation without filed surveying. By detectingthe plane and elevationprecisionof aerial triangulation and DOM,it show that the method greatly improve the efficiencyensuring the accuracy of reliability at the same time.
