摘要：The territorial data acquisition technologies vary second of the final product scale use. So it can be passed that the classical topographical survey or terrestrial laser scanners survey for engineering works, up to the satellite images multispectral analysis for regional scale and over.The classical aerial photogrammetry and LiDAR have a territory nadir (straight-down) vision, however, in many cases, the possibility to have a scene oblique vision can reveal very interesting. The Pictometry technology of images taking comes really meeting to this demand of a different vision of the environment. The system is composed of 5 cameras: one takes picture the territory in nadir way, the others four simultaneously take pictures the territory with oblique frames in 90°directions staggered. This allows to collect a series of pictures with a different point of view from the typical nadir sight. Widening the photogrammetric use of this data type, it is possible to think about exploiting the contained information in the oblique images for the three-dimensional object extraction and the 3-D models construction also in the urban zones where, a lot of times, the purely nadir images doesn't succeed in furnishing all the necessary information to such purpose. In this paper we will present the first result of a work which has the aim to find a way to use the oblique aerial images taken from pictometry system in order to improve 3D LiDAR model for a relatively small areas
