利用VirtuoZo和UCD快速制作正射影像的方法

Research on the Methods of Digital Orthophoto Map Production Using VirtuoZo NT. and UCD

提出了利用VirtuoZo系统并结合UCD相机的特点在立体环境下快速制作正射影像的方法。在研究区范围内,首先,利用无人机搭载UCD相机进行影像的获取,然后将获取的影像利用UCD相机参数和控制点参数等信息进行影像的粗纠正,接着在VirtuoZo系统中进行精纠正等处理,之后进行DEM的生成,最后可快速地进行DOM的制作。通过试验表明,该方法可快速获取精度较高的正射影像。

Research on the Methods of Digital Orthophoto Map Production using VirtuoZo NT. in a continuous block area is put for- ward. The principle and implementation of the photogrammetry theory and Remote Sensing are presented. In the study, the images are acquired by UAV, which are rectified and product the DEM. In such environment, the DOM can be done under the interface of the DPW. Additionally, the DOM can be acquired in this way. The ease study and quickly acquisition the accuracy of DOM are given at last.
