The paper describes the procedure of generating a 3D metric building model using a low-cost program package that operates on principles of multiple-image ray intersection. The advantage of the method is that stereoview is not required and we do not need a photogrammetric instrument or workstation for 3D data acquisition. The method was tested on two buildings. The program package Photomodeler version 5 was used, enabling the complete project accomplishment that includes camera calibration, image measurements, adjustments of object coordinates, generation of surface 3D models and photorendering. The phases of the project are described as well as limitations and problems encountered in practice. The results show good potentials for broad use in different applications.
