Bundler - Toolkit V3DSfMToolkit ETH-V3D Structure-and-Motion software was created by Christopher Zach. The original source code with dataset is available at Christopher Zach Open-Source page (GPL license). I have created a windows port of V3DSfMToolkit with scripting wich is available as both binary (V3dSfMToolkit1.zip) and source (github). I’ve tested this toolkit with the dataset given by Christopher Zach (see above screenshot) the reconstruction looks good but I only managed to get partial reconstruction from my own dataset. MissStereo Quasi-Euclidean Epipolar Rectification: MissStereo created by Pascal Monasse, Neus Sabater, Zhongwei Tang. I’m interested by this method to estimate the fundamental matrix without prior focal length knowledge. PhotoSynthToolkit with XSI support With the help of Julien Carmagnac (3D Graphist and XSI advanced user), I’ve duplicated the 3DS Max texture projection rendering solution for Softimage XSI: SFMToolkit with sequence matching 3D-Arch’2011
Twixtor vs StereoTracer September 2012 I came back few weeks ago from the archaeological excavation of Çatalhöyük, Turkey where this year I tried new experiments in the use of 3D technology to document and visualize ongoing archaeological excavations. Last year I did tests on site using Image Based Modeling techniques to document the investigation of the building 89, in that occasion the team of the university of California Merced directed by Maurizio Forte, were running similar experiments using instead a phase shift laser scanner, they got interesting results and the use of both these techniques in the same excavation context gave us a very good feedback on how different technologies that produce similar results (resolute 3D model) obey to different work-flow of data capturing and post processing. After this tests we gain a good knowledge on how making these tools compatible with ongoing excavations and how to manage the data in a reasonable time frame. 3D model of the Building 77 realized using Photoscan AgiSoft
insight3d - opensource image based 3d modeling software DAVID 3D Scanner 2D to 3D Suite Overview | YUVsoft 2D to 3D Suite product includes a broad range of professional tools, enhancing and simplifying stereoscopic 3D conversion and postproduction for motion-picture and TV content. The product is designed for medium-size VFX and production studios, as well as large conversion studios. It contains both versions for After Effects and NUKE. 2D to 3D Suite offers the following benefits: Depth markup propagation from key frames — decreases number of frames requiring rotoscoping for all or several objectsHigh-quality stereo generation using background reconstruction — automatic stereo generation with an essential minimization of manual workAutomatic generation of plausible depth maps in many cases — rotoscoping may only be necessary for key foreground objects and objects with complex borders Watch the tutorials on Depth Propagation and Stereo Generator basic usage (a playlist of 2 videos). 2D to 3D Suite Tool List: Technical Requirements Licensing See also:
Is Origami the Future of Tech? In 1996 a young mathematician and computer scientist named Erik Demaine became fascinated by a magic trick that Harry Houdini used to do before he made his name as an escape artist. The magician would fold a piece of paper flat a few times, make one straight cut with a pair of scissors, and then unfold the paper to reveal a five-pointed star. Other magicians built on Houdini’s fold-and-cut method over the years, creating more intricate shapes: a single letter, for example, or a chain of stars. It’s an odd subject of study for a computer science professor, but Demaine had an unorthodox background. Photographs by Leonard Greco for Bloomberg BusinessweekCurved-crease origami at Erik and Martin Demaine's shared studio at MIT When Demaine was six, he and his father started a puzzle company. It was his father who brought the fold-and-cut problem to his attention when, still a teenager, Demaine was searching for a dissertation topic. At least in theory.
Insight 3D : la photogrammétrie gratuite et open-source - Actu. sur 3DVF Lukas Mach vient de lancer insight 3D, un programme gratuit et open source de modélisation basée sur photos destiné à l'architecture. Le créateur présentes ses ambitions de façon assez simple : Concrètement, donc, il s'agit de prendre des photos d'un bâtiment, avec des contraintes sur la prise de vue : chaque portion doit se trouvr sur trois photos au moins, l'angle entre chaque photo doit être idéalement de 15 à 25 degrés, et le logiciel préfèrera les modèles avec de nombreux détails, ce qui facilite la création du nuage de points. Un système de matching manuel est tout de même présent pour les cas pathologiques. Un tutoriel au format pdf, assez basique mais qui présente l'ensemble du workflow, est présent sur le site. --------------- Suggestion de news, interview, making of ?
Using the GoPro Hero 3 for 3D Photogrammetry Modeling and Measuring Posted on Monday, September 23rd, 2013 Introduction The GoPro Hero 3 is a small, lightweight, robust, low cost, and high definition video and still camera used primarily for capturing action. The GoPro Hero 3 Black is the highest resolution version of the GoPro lineup and the one best suited to photogrammetry – the science of measurement, modeling and scanning using photographs. Due to the GoPro’s small size, low weight, wifi, and good image quality it is an interesting platform to consider for photogrammetry. This article focuses on the use of the GoPro Hero 3 Black for photogrammetry with the PhotoModeler software, and how to overcome some of the camera’s deficiences. To perform accurate 3D measurement, modeling and scanning from images, using the techniques of photogrammetry, the camera should ideally have good image quality, high resolution images, stable optics, a fixed lens, focal length neither too short nor too long, and low lens distortion.

Twixtor and depth of field : RE:Vision Effects Hi, this is the first time I post on this forum so I introduce myself. My name is Giovanni and I'm and Software Engineer with passion for Photography. I use Twixtor Pro together with an array of cameras to produce 3D pictures to print on lenticular medium. This is my website where you can have a look at the result: Now I have a question. Of course this is a trick, not a real depth of field. To summarise I would like to blur a video uniformily along both x and y axis using the information of movement along the x axis. Any idea?
