Automatic Scene Reconstruction Algorithm for Planialtimetric Applications

The development of digital photogrammetry solutions applied to aerial images has gained interest in recent years due to its diverse areas of application, besides the decreasing production costs of high-resolution cameras and unmanned aerial vehicles. The implementation of an automatic scene reconstruction algorithm by using a pair of aerial images as input is proposed in this paper, as a first approach to the full reconstruction algorithm with multiple images. The current work can be used for educational purposes as it contains the general method of reconstruction, excepting for the densification process, which is tested in this paper. The reconstruction algorithm is tested with pairs of aerial pictures taken from a controlled scene, in order to analyze its viability and then with aerial pictures taken with a drone.
