Conditions and limitations of digital satellite image pre-processing for the further 3D modeling

Abstract

Abstract. Today, 3D models of complex urban buildings are one of the most popular applications of 3D modeling. 3D models of complex urban buildings provide high data interpretation that accurately transfers information about objects or area changes and allows one to solve a number of applied tasks. The quality of the 3D models depends on the quality of the initial images and the method of the object recognition. First of all, the 3D-model building requires identification and classification building borders, which requires determination of the building roof form. The article reviews the existing classification and recognition methods for the 3D further modeling.

Comparison of selected methods of characteristic point detection in satellite images

“…An alternative solution is the detection with two-dimensional hidden Markov models [13]. Currently, the above mentioned methods are used for 3D image analysis [14]. Nowadays there is much research conducted on human identification.…”
