123D Scanner - Home made 3D Scanner Hey - have a look at my new project HERE In this project I built a 3D Scanner, that enables generating 3D models of physical objects. The files can later be viewed in 3D software (GLC Player, Sketchup, Rhino, or sites such as and even manipulated into .STL file and 3D printed. The software for this project is completely free, I am using Autodesk's 123D catch, Link:123D catch The 123D Catch is a great software, it requires taking many photos of an object all around it, and uploading it into the software, and it returns a 3D file. Since I really liked the solution but did not wanted to take the photos myself - I built an instrument that does that - description hence. Please note that this document does not intend to explain how to use 123D catch (this can be found here)

3D Printed Photograph All of these 3D models were generated algorithmically from Processing using the ModelBuilder library by Marius Watz. This library allows you to save 3D geometries in the STL file format, STL files that form a watertight mesh can be printed by a 3D printer. To get started using this code yourself, download the latest version of the ModelBuilder library, unzip the file, and copy the folder into Processing's "libraries" folder. If you have installed the predecessor to the ModelBuilder library (called the Unlekker library), you will need to delete it. Once this is done restart Processing. Download the latest version of the Processing sketch from GitHub (download as a zip by clicking on the cloud button). To run the sketch, replace the part in quotes in following line: String name = "your_file_name_here"; with the name of your greyscale image.

3D Scanner KinectFusion - Real-time 3D Reconstruction and Interaction Using a Moving Depth Camera [28C3] by CCCen 21,171 views KinectFusion Real-time 3D Reconstruction and Interaction Using a Moving Depth Camera This project investigates techniques to track the 6DOF position of handheld depth sensing cameras, such as Kinect, as they move through space and perform high quality 3D surface reconstructions for interaction. While depth cameras are not conceptually new, Kinect has made such sensors accessible to all.

Automate your Meshlab workflow with MLX filter scripts Meshlab is a great program for loading and editing XYZ point cloud data and creating polygon meshes. It also does a good job as a 3D file format converter. After you start using Meshlab for awhile you will typically use the same filter settings over and over again for every project. Meshlab allows you to automate your workflow by creating your own Meshlab .MLX filter scripts. These filter scripts are in XML format and can be run from the Meshlab GUI or from the command line version of Meshlab called meshlabserver. If you run into trouble using Meshlab there is a SourceForge discussion forum that is quite helpful. I discovered Meshlab when I started processing aerial images with Bundler / PMVS and needed an opensource program to edit Stanford Triangle Format .PLY files . This blog post is probably one of the most hyperniche topics I have written about. Creating a Meshlab MLX Filter Script You can edit a Meshlab filter by selecting the Show Current Filter Script menu item. Example command:

Rendering results with Meshlab | hackengineer Posted: 26th February 2012 by hackengineer in Computer Vision Tags: 3D , meshlab , point cloud Meshlab is pretty great for 3D point clouds and its free! Here are a few steps that help really make the point clouds look good. Open Meshlab and open the .xyz file from the 3D camera Delete any points that look like they dont belong ( if you only see a small group of points you are probably zoomed out really far dude to a rogue point; delete it and zoom in) Orient the pointcloud so that it represents the original scene (looking straight at it). Lets add some color to the depth to make it stand out (darker as depth increases). We should have a good looking pointcloud at this point. And there you have it! <–Previous Project Home Be Sociable, Share!

SLAMDemo - rtabmap - Demo of 6DoF RGBD SLAM using RTAB-Map - RTAB-Map : Real-Time Appearance-Based Mapping In this example, we use a hand-held Kinect sensor: we assemble incrementally the map depending on the 6D visual odometry, then when a loop closure is detected using RTAB-Map, TORO is used to optimize the map with the new constraint. We did two loops in the IntRoLab robotic laboratory of the 3IT . The first image below is the final map without optimizations. The second image is the final map with TORO optimizations with RTAB-Map detected constraints. The ROS bag for the demo is here : kinect_720.bag . This only works with ROS, tested under Ubuntu 12.04 / ROS Fuerte (edit: work also on Groovy). $ svn checkout http : //utilite.googlecode.com/svn/trunk/ros-pkg utilite $ svn checkout http : //rtabmap.googlecode.com/svn/tags/6dSLAMdemo/ros-pkg rtabmap $ svn checkout http : //rtabmap.googlecode.com/svn/tags/6dSLAMdemo/visual_slam visual_slam $ rosdep update $ rosdep install visual_slam $ rosmake visual_slam To try the demo, type: $ rosbag play -- clock kinect_720 . bag ( visual_slam_demo.launch )

ReconstructMe and Realistic 3D Scans | 3D Printing at UMW May 10, 2012 in Scanning by Tim Owens I’ve been playing recently with a great new piece of software called ReconstructMe which is free for now and Windows only. It uses the Xbox Kinect (an incredibly worthwhile investment for 3D scanning) to create 3D models. The greatest thing about this software is it stitches together scans in realtime so 360 degree scanning is easier than it has ever been before and the results are stunning. For this print I sat in a rolling chair with the Kinect mounted on a tripod faced at an angle and slowly turned 360 degrees to build it. In many ways it feels like the advances being made in this field are so incredibly fast moving that it’s hard to keep up. Building your own 3D scanner out of off-the-shelf parts So you have an animation and simulation project, and want to scan people to get their high-resolution 3D meshes. At that point you have wide variety of different options based on different capture technologies, big bulky machines, hand-held devices and scanners that can take quite a while to obtain a scan. So what do you do when you don’t necessarily have a lot of permanent space, when you ideally want to obtain a scan in a single shot, and you want to do all that on a budget? Well, you build your own solution of course. You visit your local camera vendor, and empty their basket of 64 Canon Powershot A1400 cameras, which should suffice to build 8 portable 3D scanning poles. Throw in a significant amount of USB cables, add some USB hubs, grab some wood and hardware from your local DIY store, add some bright LED strip for lighting, and you have all the ingredients necessary to build your own scanner. The construction: And there you have it. The first results:
