Abstract:
In this paper we describe the development of a Computer Platform, whose goal is to recover the three-dimensional (3D) structure of a scene or the shape of an object, using Structure From Motion (SFM) techniques. SFM is an Active Computer Vision technique, which doesn’t need contact or energy projection. The main objective of this project is to recover the 3D shape of an object or scene using the camera(s)’s or object’s movement, without imposing any kind of restrictions to it. Starting with an uncalibrated sequence of images, the referred movement is extracted, as well as the camera(s) parameters, and finally, the 3D geometry of the object or scene is inferred. Shortly, in the first section of this paper the goals are defined; in the second, the computer platform is presented, as well as some experimental results; in the third and last section, the conclusions relative to the study and work done are drawn and, finally, some perspectives of future work are given.
