Disclosed herein is an apparatus for providing spatial contents service which includes a spatial contents insertion unit, a spatial contents generation unit, a topological relationship generation unit, and a spatial contents composition unit. The spatial contents insertion unit extracts spatial objects included in an image. The spatial contents generation unit generates primary spatial contents corresponding to the image. The topological relationship generation unit compares spatial location information of the primary spatial contents with spatial location information of one or more pieces of secondary spatial contents, and defines a spatial topological relationship between the primary spatial contents and the secondary spatial contents. The spatial contents composition unit couples or links the secondary spatial contents, which has a spatial topological relationship with the primary spatial contents, to the primary spatial contents.

A system for generating spatial information using an unmanned aerial vehicle may collect area information of an area where the unmanned aerial vehicle is located, obtain image information of the area where the unmanned aerial vehicle is located, and integrate a time code into the image information. Next, the system for generating spatial information may map integrated information in which the time code is integrated into the image information and the area information, and generate three-dimensional (3D) spatial information including a true orthophoto generated by performing a true ortho-correction for a mapping result.

Provided is a method and apparatus for classifying geological materials using image processing techniques. The method and apparatus classify geological materials including stones, rock samples, and rock surfaces according to type and state by sequentially applying image processing techniques, such as a color space analysis, a granulometry analysis, texture parameter extraction and texture statistics extraction, to digital images of the geological materials. Since the method and apparatus extract quantitative figures that represent an entire image region by applying various image processing techniques, such as the color space analysis, the granulometry, the texture parameter extraction and the texture statistics extraction, to the digital images of the geological materials, the geological materials can be classified, which is not possible using a conventional image processing technique.

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.
