A New Expeditious Method for Buildings 3D Models Creation

In recent years buildings 3D models have known a great evolution, being used in a wide variety of domains such as industry, cultural heritage, architecture, etc. where high precision is needed and also a high level of detail. For many years, close-range photogrammetry has been dealing with the extraction of high accurate informations from images. But, in order to obtain this precision, we need to use a camera whose intrinsic parameters are determined with high accuracy and we also have to respect some conditions when images are acquired. Therefore, there are some domains and applications, were buildings 3D models can be created with low accuracy, such as GIS applications, but without any lost of detail. So, this paper presents a new method for buildings 3D models creation in an expeditious mode, based on digital images acquired with a digital non-metric camera. The advantage of this method is that the camera doesn't require calibration and we can obtain a very realistic 3D model with a high level of detail and meters accuracy
