Using Kinfu Large Scale to generate a textured mesh This tutorial demonstrates how to use KinFu Large Scale to produce a mesh (in meters) from a room, and apply texture information in post-processing for a more appealing visual result. The first part of this tutorial shows how to obtain the TSDF cloud from KinFu Large Scale. The second part shows how to convert the TSDF cloud into a uniform mesh. The third part shows how to texture the obtained mesh using the RGB images and poses we obtained from KinFu Large Scale. TSDF Cloud This section describes the TSDF Cloud, which is the expected output of KinFu Large Scale. You may be wondering: “What is the difference between a TSDF cloud and a normal point cloud?” Figure 1: The cube is subdivided into a set of Voxels. As you may already know, the way in which the TSDF volume is stored in GPU is a voxel grid. At the time of data extraction, the grid is traversed from front to back, and the TSDF values are checked for each voxel. Figure 2: A representation of the TSDF Volume grid in the GPU. $ . $ .
Boya.ca - Robótica de hardware abierto y software libre Hilbert Engine Multidimensional problems require a multidimensional solution Hilbert Technology Inc. holds seven issued US patents on its unique mathematical method for storing, organizing and analyzing data. The core of the Company’s software technology, the Hilbert Engine, uniquely transforms relational data into a multidimensional coordinate system (Hilbert space) which enables new capabilities and flexibilities in searching, sorting and querying data. Once data are migrated (transformed) into Hilbert’s multidimensional space, the data are immediately viewable for inclusion into any analysis without the costly and time-consuming normalization step. The Hilbert Engine provides business users with distinct competitive advantages for solving the most complex data mining, data matching, and entity extraction problems within large data sets.
functioning Nvidia Optimus in Mint13/14/15 To fix Nvidia Optimus problems install 'Bumblebee' and 'laptop-mode-tools'. These are working together to manage fan and cpu power-saving options. first: 1) sudo add-apt-repository ppa:bumblebee/stable This will add bumblebee to the repository. After initiating Code 1 , in terminal write: 2) sudo apt-get update 3) sudo apt-get install bumblebee bumblebee-nvidia virtualgl linux-headers-generic laptop-mode-tools When installing items finished, you need to alter some files as following: 4) sudo gedit /etc/bumblebee/bumblebee.conf Go to section starting with [bumblebeed] and add 'nvidia' to => Driver= should look like => Driver=nvidia Then search for this part: [driver-nvidia] and look around in the section to find two lines like the following, if not add it: KernelDriver=nvidia-current Module=nvidia Also read comments everytime, those are written for you to have a clue of what's going on. Now, save and close the document, you'll come back to terminal. 5) sudo gedit /etc/init/bumblebeed.conf start on
3D Scan 2.0 Scanning The only things you need are our framework, the Kinect and some AR markers. Therefor we constructed some Scan Tablets Point Cloud After scanning the object you get a colored point cloud. See more point clouds in our 3D Gallery ! Reconstruction Using a Poisson Surface Reconstruction algorithm you get a mesh which is then colored with our color mapping algorithm. Read more about the Poisson Surface Reconstruction. Quick Start » Get ready to scan: First step: Download our framwork Second step: Read the instructions to compile the framework. » Any Questions? Check the Documentation.
CODESYS – industrial IEC 61131-3 SPS-Programming Using Microsoft Solver Foundation to solve linear programming tasks - Gunnar Peipman's ASP.NET blog One of soon-to-starts projects uses linear programming for some optimizations. As it is not very familiar topic to me I started looking for examples and tools so I am prepared better when action starts. In this posting I will show you how to solve simple linear programming tasks using Microsoft Solver Foundation – free math package available by DevLabs. Linear programming is used in many real-life calculations: business, economy, transportation, energy, telecommunications, manufacturing etc. The goal is holy: to make optimal decisions and save resources like money, time and materials. Prerequisites What is linear programming? Linear programming is specific case of mathematical programming or optimization. We have function to be maximized: f(x,y) = c1x1 + c2x2. Based on this information we will find the maximum value. Example exercises I found some good linear programming exercises from Brunel University home page. A company makes two products (X and Y) using two machines (A and B).
How to get Nvidia's proprietary driver to work This is a simple tutorial to help you get the Nvidia proprietary driver to work on Linux Mint 9 (Isadora) using Grub2. Part I (Why) The open source community has decided to create their own open source video driver for Nvidia video cords, called Nouveau. Part II (How) I followed this guide to get mine working, written by ferro. Good luck. Tags: Nvidia, Driver, Nouveau Created: 6 years ago. Other tutorials from ron_o No other tutorials. 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.
Linear programming solution examples OR-Notes are a series of introductory notes on topics that fall under the broad heading of the field of operations research (OR). They were originally used by me in an introductory OR course I give at Imperial College. They are now available for use by any students and teachers interested in OR subject to the following conditions. A full list of the topics available in OR-Notes can be found here. Linear programming solution examples Linear programming example 1997 UG exam A company makes two products (X and Y) using two machines (A and B). At the start of the current week there are 30 units of X and 90 units of Y in stock. The demand for X in the current week is forecast to be 75 units and for Y is forecast to be 95 units. Formulate the problem of deciding how much of each product to make in the current week as a linear program. Solution Let x be the number of units of X produced in the current week y be the number of units of Y produced in the current week then the constraints are: maximise
Printer Driver For Fuji-Xerox DocuCentre-II C3300 | World Of Nubcraft This post was published 1 year 1 month 11 days ago which may make many or all of its content outdated. Please follow at your own risk. Today, I was trying to print something at work and found out that our old Brother MFC 8840D printer was now replaced with a Fuji-Xerox DocuCentre-II C3300. The printer comes up in the network and is successfully identified (full printer name), but the driver is not listed anywhere. The above requires the source code to be compiled. Or you can search for other tutorials on compiling from source on Ubuntu. The first link above has the source code link and other information. Just unpack the zipped file. Lastly, the ppd file, named fxlinuxprint.ppd, should be located at the following location: /usr/share/cups/model/FujiXerox/en. Related Posts: No Related Posts
