homemade 3d scanner - the working principle setup:the basic setup consists of a line laser module, a pc cam and a stepper motor controller card connected to one stepper motor. the laser is mounted on top of the stepper motor axis. the camera is placed at a well defined position with respect to the laser (the maximum detail resolution of the digitized part is determined by the resolution of the stepper motor, its gearing and the resolution of the cam). the object is placed in front of the cam in such a way that as much as possible of it is visible to the cam. at the same time the laser should be able to sweep the entire part, generating a well visible line on the object. scanning procedure:1) turn on laser 2) get image from cam3) analyze image, find laser line 4) calc 3d position of line points5) move laser 6) loop 2 to 5 until done7) turn off laser 8) mesh points calculating the position of the points in space is actually pretty simple vector algebra: λ×c = d + η×l1 + μ×l2

About My3DScanner What's New in iOS: iOS 7.0 iOS 7 is a major update with compelling features for developers to incorporate into their apps. The user interface has been completely redesigned. In addition, iOS 7 introduces a new animation system for creating 2D and 2.5D games. Multitasking enhancements, peer-to-peer connectivity, and many other important features make iOS 7 the most significant release since the first iPhone SDK. This article summarizes the key developer-related features introduced in iOS 7. This version of the operating system runs on current iOS devices. For late-breaking news and information about known issues, see iOS 7.0 Release Notes. User Interface Changes iOS 7 includes many new features intended to help you create great user interfaces. UI Redesign The iOS 7 user interface has been completely redesigned. Apps compiled against the iOS 7 SDK automatically receive the new appearance for any standard system views when the app is run on iOS 7.

3D Scanning System The last couple of years have seen an explosion in home fabrication, with fantastic projects like RepRap and Fab@Home really helping to bring the open source community together. Unfortunately, 3D scanning — in many ways the flipside of the home fabrication coin — seems to have fallen by the wayside. I decided to start the 3D scanning ball rolling by creating the SplineScan computer-controlled turntable. The turntable uses a gearbox for precise positioning, and has fixings for lasers, lights, and cameras. The obvious use of the turntable is for 3D scanning, although it can be adapted very easily to rotate objects for accurate photography or interactive display. I’m currently using the turntable to archive and measure ancient artifacts as part of my Ph.D. studies ( and I have to say that I’m very happy with the results so far. The parts list might look a bit daunting, but the project is not difficult to make. Chassis This is the backbone of the scanner.

3d modelling software How to start out with 3d printing In the first of the Personal Factory 3d printing tutorial series we’re looking at popular software packages you can use to create your designs. Not all 3d software is created alike – some is intended for creating vast landscapes, others specialise in rendering and visualisation. We’re interested in software focused on both organic & primitive geometry modeling with support for stereo-lithography (.STL) files. Thanks to years of 3d software development there are now many methods to build a 3d models, below are some of the means you may come across… Polygon - The most common modellers available, however many include support for other types of modelling including NURBS, splines, sculpting & SubD. NURBS - Not as common as polygon modellers, NURBS allow a mathematical level of accuracy over polygons, so are very useful for 3d printing. Sculptural - The most well known is zBrush, although they are also found in many plug-ins or features within other packages.

Scanalyze: a system for aligning and merging range data Scanalyze is an interactive computer graphics application for viewing, editing, aligning, and merging range images to produce dense polygon meshes. It was the primary tool used in the Digital Michelangelo Project (1997-2004) to assemble 3D models of Michelangelo's statues from laser range data. It was also used heavily in the Digital Forma Urbis Romae Project (1999-2006). This software distribution contains the source code for Scanalyze, as well as binaries compiled for SGIs (running IRIX) and PCs (running Linux or Windows). Table of contents Overview of the Scanalyze system Scanalyze processes three kinds of files: triangle-mesh PLY files (extension .ply), range-grid PLY files (also with extension .ply), and SD files (extension .sd). Scanalyze is capable of displaying hundreds of PLY or SD files at once. Once these PLY or SD files have been loaded, they can be pairwise aligned using a variety of techniques - some manual (i.e. pointing and clicking) and some automatic. Citations Linux
