摘要： Disclosed is a digital photogrammetric method and apparatus using the integrated modeling of different types of sensors. A unified triangulation method is provided for an overlapping area between an aerial image and a satellite image that are captured by a frame camera and a line camera equipped with different types of sensors. Ground control lines or ground control surfaces are used as ground control features used for the triangulation. A few ground control points may be used together with the ground control surface in order to further improve the three-dimensional position. The ground control line and the ground control surface may be extracted from LiDAR data. In addition, triangulation may be performed by bundle adjustment in the units of blocks each having several aerial images and satellite images. When an orthophoto is needed, it is possible to generate the orthophoto by appropriately using elevation models with various accuracies that are created by a LiDAR system, according to desired accuracy.
