Mapillary/OpenSfM. Orthogonal / Nadir « FLIGHT RIOT. It seems that it is now possible and relatively easy to modify a digital camera to capture wavelengths necessary for producing Vegetation Indexes such as Normalized Differential Vegetation Index (NDVI).
Recently, I tested some of the work being done by folks at publiclab.org along with others and some amazing results are coming to fruition. I’ve been communicating with Chris Fastie and Ned Horning over the past month or two regarding methods for generating NDVI and other Vegetation Indexes (VI) from a single digital camera. If you look at the Infragram project on kick starter or on publiclab you can read about their current project, which is intended to result in a low cost single camera solution for NDVI and other VI production. I simply jumped the gun and made my own modified camera. The main reason I proceeded this way is that I rely on Canon cameras for UAV mapping because of the CHDK option. Okay, so here is what you need to DIY. Open Source Photogrammetry. Software for structure from motion. A few people who I have spoken with recently expressed an interest in accessing freely available structure from motion (SFM) software.
This note provides a brief introduction to SFM with information about a set of open source software for processing SFM data sets on a desktop computer. This is quite terse but hopefully useful or at least enough to pique some interest in working with SFM. SFM is a process of building 3-dimensional models using images of a feature that were acquired from different locations around the feature. My personal interest is in imaging landscapes using small aerial platforms like kites/balloons/UAS but many outdoor SFM examples focus on urban features such as buildings and statues. 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: $ . Home. 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: 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.

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. All the features and modules are unit tested. This test driven development ensures that the code works as it should and enables more consistent repeatability.
Structure from motion. Structure from motion (SfM) is a range imaging technique; it refers to the process of estimating three-dimensional structures from two-dimensional image sequences which may be coupled with local motion signals.
It is studied in the fields of computer vision and visual perception. In biological vision, SfM refers to the phenomenon by which humans (and other living creatures) can recover 3D structure from the projected 2D (retinal) motion field of a moving object or scene. Ppt_check_database_en [DADP]
