Open Source Photogrammetry: Ditching 123D Catch – We Did Stuff

Open Source Photogrammetry: Ditching 123D Catch – We Did Stuff
This is part one in a series on open source photogrammetry. In part two, I’ll flesh out more VFX-centric application of this workflow. Before I start, big thanks to: Dan Short: for showing me his awesome 123d models that sparked this whole ideaHannah Davis: debugging + emotional support + snacks So a few weeks ago, Dan Short showed me 123D Catch. It was awesome. Until Dan showed me some models he generated from exhibts at the AMNH I didn’t really get the point of Catch…so what, you have a model of your water bottle…but what Dan showed me was that it worked incredible well on environments too: The Hall of African Mammals or even the penguin diarama from the infamous whale room! I remembered seeing something like this years ago: a product demo called Photosynth from Microsoft, which did this sort of reconstruction from thousands of tourist photos of the Notre Dame Cathedral. Photo limits: the iphone app seems to allow a maximum of 40 images. Here are the steps: Part 1: VisualSFM Caveats

SynthEyes Camera Tracker - Andersson Technologies LLC What is SynthEyes? SynthEyes is a Windows, Mac, or Linux software application for 3-D camera-tracking, also known as match-moving, which is widely used in film, television, commercial, and music video post-production. SynthEyes can look at the image sequence from your live-action shoot and determine how the real camera moved during the shoot, what the field of view (~focal length) was, and where various features were in 3-D, so that you can create computer-generated imagery that exactly fits into the shot. What can SynthEyes do for me? What are its features? Take a deep breath!

SFM Scanner by wstrinz Structure from motion is a class of algorithms that take information about point correspondences between images and use them to reconstruct 3D scenes. While some pretty serious math is involved, no specialist hardware is required aside from a camera. We've seen lots of structure from motion based 3D scanning solutions already this year, the best known being my3dscanner.com/, but all of them are closed source. This is hard to deal with when I see cool things like Qi Pan's ProFORMA software ( but can't use them or look at how they work. The Art of Photogrammetry: Introduction to Software and Hardware Our brains perceive depth by comparing the images that our eyes see. If you alternatively close each of your eyes, you will notice that the object you see will seem to shift left and right. An object that is closer, will seem to shift more than an object that is farther away. That's stereoscopic vision, and the core concept behind creating the illusion of three-dimensional objects and space from two 2D images. Your brain can use this information to subconsciously calculate and tell you how far away an object is supposed to be. In a similar way, photogrammetry is a photography technique using software to map and reconstruct the shape of an object, by comparing two or more photographs.

Deformers at play: Coiling Wires Hey guys, thanks for the feedback. Glad that this was helpful. There's more on the way. As you know, character animation and it's tools are very broad topics. Photogrammetric Modeling + GIS Spring 2012 Edition Better methods for working with mesh data By Rachel Opitz, University of Arkansas, and Jessica Nowlin, Brown University The method of bringing photogrammetric data into a GIS to create simple visualizations described in this article is being used in ongoing University of Michigan excavations at Gabii, Italy. This article as a PDF. Sensor Fusion We propose an automatic procedure for combining digital images and laser scanner data in order to have a full representation of a scene. In particular, this procedure will serve photogrammetric close range applications such as 3D digital preservation and documentation of cultural heritages by generating comprehensive virtual reality models. Our method is based on a bundle block adjustment for the orientation estimation of generated images from laser data and camera images by means of an optimized Structure-from-Motion reconstruction method. This results in having target-free registration of multiple laser scans and absolute image orientations. The developed procedure was applied to the dataset of the Lady Chapel of the Hirsau Abbey ruins, which was acquired using the Faro Focus3D with 9 scans; see figure 1 right.

How to make 3d scan with pictures and the PPT GUI More than ever before 3D models have become a "physical" part of our life, how we can see in the internet with 3D services of printing. After download and unzip you have to edit the ppt_gui_start file putting the right path of the program (in orange). Now, if you are in Linux is only run the script edited: $ . Sensors & Systems - 3D Laser Mapping Offers Innovative Visualisation Software Details Jan 15 2014 by 3D Laser Mapping 3D Laser Mapping has announced new software that makes it much easier to access and view laser scanned data. The innovative Arena 4D software provides a common reference frame for a wide variety of data sources including the billions of individual measurements captured by static laser scanners or mobile mapping systems – such as 3D Laser Mapping’s StreetMapper. This single ‘arena’ allows for the integration of multiple data types and formats, including all common LiDAR datasets, within an easy to use environment and without the need for, or expense of, specialist hardware.

Girl Portrait Modo 601 beta work. How it was made: Concept sculpt and Retopo Image sculpted details Body Scanning We scan a full body in ultra high resolution 15k colour using our 80 X DSLR photogrammetry system. If you are looking for a portable fast body scanning solution we can use our ultra compact Artec M scanning system. Using the Artec we can scan a full body in about 2 minutes and provide you with a model within the hour. Using the GoPro Hero 3 for 3D Photogrammetry Modeling and Measuring Using the GoPro Hero 3 for 3D Photogrammetry Modeling and Measuring Posted by Alan Walford on Mon, Sep 23, 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.

openMVG: "open Multiple View Geometry" "open Multiple View Geometry" is a library for computer-vision scientists and especially targeted to the Multiple View Geometry community. It is designed to provide an easy access to the classical problem solvers in Multiple View Geometry and solve them accurately. The openMVG credo is: "Keep it simple, keep it maintainable". OpenMVG targets readable code that is easy to use and modify by the community.

Neo-Geography Toolkit - Stereo Pipeline Examples The following HiRISE 3D surface models were built using the Stereo Pipeline. We provide them here as examples of the data products that can be generated using the software. For more information about these examples, refer to the "Data Processing Examples" Appendix in the Stereo Pipeline User's Guide. HiRISE Columbia Hills (Crop)
