Issue Date: | 2003 | Journal: | Lecture Notes in Computer Science | Conference: | 9th International Workshop on Computer Aided Systems Theory | Abstract: | In this paper, we present a vascular tree model made with synthetic materials and which allows us to obtain images to make a 3D reconstruction.We have used PVC tubes of several diameters and lengths that will let us evaluate the accuracy of our 3D reconstruction. In order to calibrate the camera we have used a corner detector. Also we have used Optical Flow techniques to follow the points through the images going and going back. We describe two general techniques to extract a sequence of corresponding points from multiple views of an object. The resulting sequence of points will be used later to reconstruct a set of 3D points representing the object surfaces on the scene. We have made the 3D reconstruction choosing by chance a couple of images and we have calculated the projection error. After several repetitions, we have found the best 3D location for the point. | URI: | http://hdl.handle.net/10553/11766 | ISBN: | 3540202218 | ISSN: | 0302-9743 | DOI: | 10.1007/978-3-540-45210-2_56 | Source: | Moreno-Díaz R., Pichler F.
