AUTOMATIC MATCHING METHOD OF DIGITAL AERIAL IMAGES USING LIDAR DATA

摘要

PURPOSE: An automatic matching method of digital aerial Images using LIDAR data is provided to supply high accurate 3D spatial information by generating a DSM through an accurate ground point of a radiator and the ground point extracted from an image-matched aerial image. CONSTITUTION: An image point indicating a ground point is detected from a duplicated aerial image, and the accuracy of image matching is improved by using virtual LIDAR(Light Detection And Ranging). Through the extraction of vertical error of the ground point, the image matching is verified(S60). Through the matched aerial images and LIDAR data, a DSM(Digital Surface Model) is created(S30). The radiator is collected(S40), and the DSM is updated(S50).
