Realtime 3D Face Scanning. 3D Printering: Scanning 3D models. 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. 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. ReconstructMe and Realistic 3D Scans. 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. Testing ReconstructMe - how to use Kinect to capture 3D models in real-time. 3D Scanning Made Easy. Demonstration of RGB Demo0.7 on UBuntu12.04 - 3d reconstruction using kinect. Installing Libfreenect Installing Open-NI, Sensor kinect, Avin2Sensor patch and NITE ( Note : only 1.5xx versions work with RGB demo source not the github) Installing PCL-1.6 Installing OpenCV-2.3.1 Installing RGB demo Installing QT Note: PCL-1.6, OpenCV2.3.1 and QT libraries should be downloaded from Ubuntu repositories, otherwise there will be a conflict Getting started with OpenKinect (Libfreenect) Here are the list of Ubuntu Kinect Installation commands.
DSLR + DEPTH Filmmaking. 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 third and fourth images are closer examples of before and after map optimizations.
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).

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).
We will now compute the normals for each point. 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. SCENECT 5.1 Tutorial MeshLab Create a mesh for 3D printing. 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) VirtuZoom Microscope 3D-Scanner by virtumake. Www.diy3dscan.com. Mesh.brown.edu/dlanman/research/3DIM07/lanman-SurroundLighting.pdf. Update: Realtime 3D for you too! 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"; Guest blog Deepak Mehta: (123D)Catch it if you can! Recently Autodesk released 123D Catch for the iPhone.
But how useful is the app from a 3D printing perspective? Deepak Mehta, a technology evangelist for 3D printing, takes it to the test and tells about his experiences. Let me start with a short introduction of the functionality of 123D Catch for the iPhone. This is basically a front-end interface to the cloud service by Autodesk, which is also used by the Windows and the iPad version. The idea is that, through a combination of a good camera and the data from the location and gyro sensors in the iPhone, you can easily locate the angle at which the photo of the object was taken.
For good results you need to take care of several things:
