RESUMO

This dissertation presents an improvement of the Three-Dimensional Hybrid Imaging System (SITH) that is used to obtain a three dimensional surface relief of a particular region from the same two consecutive air frames it. Photogrammetry is the science and technology used to obtain reliable information from images acquired by sensors. Improving the automation of the SITH will consist of points obtained using the technique of Invariant Feature Transform Scale (SIFT - Scale Invariant Feature Transform) pair of stereoscopic images obtained by aerial metric cameras, and the use of means of cubic spline interpolation for smooth surfaces produced by the same three-dimensional, providing a clearer view of the details of the study area and aiding in effective prevention against landslides in hazardous locations from an urban planning appropriate. The computational results show that the incorporation of these methods to the program SITH had good results.
