Openni Software Installation Application Notes for the Pandaboard ES Camden Smith ECE 480 Design Team 2 11/16/12 OpenNI Software Installation Application Notes for the Pandaboard ES Camden Smith ECE 480 Design Team 2 11/16/12 OpenNI Stands for Open Natural Interaction, it is not only software but an organization focused on creating and improving the software for human (or “natural”) user interfaces used for natural interaction devices. Natural Interaction Devices (NID) is a fairly new technology that can detect human or natural movement (such as the Microsoft Xbox Kinect or the ASUS Xtion), there are only a few different NID's that exist today but this tutorial will be explaining the software used to program one of these devices (specifically the ASUS Xtion). The hardware and software packages that will be used will be very specific to this tutorial but I will provide the links to the packages when necessary. However, in this tutorial I will only cover the steps to install the software for OpenNI. To overview what will be covered in the tutorial I've created steps Step 1 – Project Requirements The hardware and software used to test and write this tutorial is as follows, if I don't specify a version or specific hardware it shouldn't matter: -Computer with a Dual Core Processor (I'll cover OS requirements/details below) -Pandaboard ES -ASUS Xtion -Necessary power cords to power the devices respectively -OpenNI, Sensor and NITE Software -The Pandaboard program our group created for this project Step 2 – Software and Operating System, and Tips before OpenNI Installation: Part 1 - Software and Operating System: No matter what operating system you are running (Mac OSx, Linux, or Windows) the necessary files for OpenNI, the Sensor software, and NITE can be found at the following open source location. For our project we used Ubuntu 12.04 on our Pandaboard, but if you are using something else download the correct files here (keep in mind that the Pandaboard will only support certain OS's and software packages due to the ARM processor). Download the files and copy them to your Pandaboard: http://www.openni.org/Downloads/OpenNIModules.aspx Part 2 -Tips before installation: Before you start the installation make sure your Pandaboard has been installed with the correct version of Linux that has been specified in the files you downloaded (most likely Ubuntu 12.04). After the Pandaboard was installed with Ubuntu we made sure the system was up to date, the OS was configured and working properly. We then installed eclipse and any necessary libraries for C++ debugging and programming. Eclipse was a very important program to get our group’s software working with the OpenNI software so we want to be sure it is configured properly. But since we have not installed the OpenNI software yet, our program will not be able to compile in Eclipse. I will come back to this after I have covered the OpenNI installation. After we did finished our full installation and setup of Ubuntu on our Pandaboard, we created an image of the install just in case we needed to do a quick reload to start over (unfortunately we had to do this a couple of times). Also, you may want to install Eclipse before creating an image of the install or you will have to do it again. Now you’re ready to begin your OpenNI installation and you have a backup copy just in case something goes wrong! Step 3 - OpenNI/NITE/Sensor Software Setup and Installation Part 1 – Software and Packages Setup: In the directory you copied the files to extract the files here, open a terminal and navigate to this directory. In Ubuntu you will need the following packages before installing the software: mono- complete, libusb-1.0-0-dev, and freeglut3-dev. So run the following command to install the packages. $ sudo apt-get install freeglut3-dev mono-complete libusb-1.0-0-dev freeglut3-dev Part 2 – Installing OpenNI/NITE/Sensor Next, in your terminal navigate to the OpenNI folder you extracted in Step 2 and type: $ sudo ./install.sh Do the same thing for both Sensor and NITE. If everything has gone smoothly and you haven’t received any errors during the install, then you've now successfully installed the OpenNI, Sensor and NITE software! We now need to configure the software sources needed by the OpenNI software. Step 4 – Installing the software sources Create a directory in your home folder and call it “Xtion”. Navigate to this directory in your terminal window and run the following command: $ git clone https://github.com/OpenNI/OpenNI.git This will download the OpenNI repository into your directory. After this has completed navigate to this directory “~/Xtion/OpenNI/Platform/Linux/Build” and run the following command: $ make && sudo make install This will install the necessary sources needed by the OpenNI software. Next we need to input the license key for the primesense software which was provided via Primesense for open development. Step 5 – Primsense License Setup Open the following file “Xtion/OpenNI/Data/SamplesConfig.xml”, the third line (or node of the XML file) is commented out and should be in all blue text. It should be between these two line , first with the code <Licenses> and then </Licenses>. Replaced the code that is commented out with the following line: <License vendor="PrimeSense" key="0KOIk2JeIBYClPWVnMoRKn5cdY4"/> This should look like this: <OpenNI> <Licenses> <License vendor="PrimeSense" key="0KOIk2JeIBYClPWVnMoRKn5cdY4"/> </Licenses> After you save the file, you've successfully installed your Pandaboard with the software necessary to begin your human tracking using the ASUS Xtion! Step 6 – Eclipse Installation and Initial Setup: Part 1 – Installation: Eclipse is an open source programming management interface and debugger. You can download it in the software manager in Ubuntu or from the official Eclipse website to recieve the latest version. After the installation of Eclipse is complete, go ahead and open Eclipse. Depending on the method you installed eclipse you may have to launch it a different way. If you cannot find eclipse in your applications, open a terminal and type the following command: $ eclipse & Part 3 - Using our software with Open NI: Go ahead and open Eclipse, it will prompt you to choose a workspace. Navigate to the folder containing our group project (doesn’t matter if you’ve extracted the zip file yet) and select this folder as your workspace. After Eclipse has opened, go to “File->Import…”, then expand general and select “Import existing project into workspace”. If you have not extracted the project yet there is a selection in which you can choose to import the archive, otherwise go ahead and select the project folder and hit finish. The project should then appear in the left project navigator panel. Selected the project and go to “Project->Build All”, this should build your program. If you have received any errors during the project build, please refer to my “Common Bugs” documentation at the end of this tutorial. If you did not receive any errors, go to “Run->Run without Debugging”, and this will compile your program. If this completed successfully you should receive the following before connecting to your host. If this did complete successfully, please refer to further documentation on connecting to the Pandaboard using Network Protocols. [SYS] Application initialized. [NET] Starting TCP Server... [NET] TCP Server started on port 9999 [NET] Waiting for clients to connect... Examples and Testing I will provide a few ways to run a few of the programs that have been installed but unfortunately I will only provide minimal debugging for running these programs. For running the tracking software: Open a terminal, find the OpenNI folder you extracted in Step 2 and navigate to the following location “OpenNI/Samples/Bin”. To run one of the sample programs type the following command: $ ./Sample-NiUserTracker This will begin the user tracking software if everything is configured and hooked up correctly. To start the model software that plots the tracking software run the following command: $ ./NiViewer Figure 1 - http://luka.tnode.com/media/cache/ gallery/kinect2_display_image.jpg Figure 1 shows an example of what this software should look like. If there is a problem with your connections or the system receives some kind of invalid information that causes it to segmentation fault, you may receive the following followed by an empty re-prompt: “One or more of the following nodes could not be enumerated:” It should specify what is not being detected properly or what it is not able resolved, but further documentation for this and other methods of running the sample software can be found online. Common Bugs There was a few bugs we ran into during the installation, we were able to run the OpenNI software and the software we created on a previous version of Ubuntu (such as 11.10). But during one installation we were required to full update and upgrade the Ubuntu system to 12.04 before the project was able to compile in Eclipse. So I recommend not attempting to do this and just upgrade your system to 12.04 (or whatever the OpenNI packages you download specify) before you begin the installation. There are countless bugs in Eclipse and one of these bugs may cause some of the header files, in the eclipse project we created, to not detect the headers. Something that might fix this is checking the include destinations in your project settings. There are numerous tutorials on the bugs that are caused in eclipse online, if you are receiving a lot of errors or bugs caused by eclipse you may want to document some of these tutorials.

For applications in which high quality 3D is required, i.e., 3D building models of centimeter-level accuracy, accurate and reliable calibrations of these sensors are required. This paper presents a new model for calibrating the depth measurements of RGB-D sensors based on the structured light concept. Additionally, a new automatic method is proposed for the calibration of all RGB-D parameters, including internal calibration parameters for all cameras, the baseline between the infrared and RGB cameras, and the depth error model.

Frohman was charged with helping Intel establish a small chip design center in Haifa, which at the time, was Intel’s first outside the U.S. The rest, as the cliché goes, is history. In a little over a generation, the Israeli semiconductor industry has grown to now employ more than 20,000; annual revenues are about US $5 billion. Intel, for instance, now has about 9,900 employees in Israel and is planning to invest almost $6 billion in upgrading its Kiryat Gat fab facility. In fact, since 1974, Intel has invested about $10.8 billion in the Israeli semiconductor industry. “We’ve exported goods worth $35 billion most from our production centers in Kiryat Gat and Jerusalem,” said Intel VP and Intel Israel CEO Maxine Fassberg. Sol Gradman is editor of TapeOut, a publication covering the semiconductor industry, and also chairs ChipEx, the country’s largest annual semiconductor/microelectronics conference. Gradman said Israel’s semiconductor industry today comprises three types of companies – fabless, multinational design centers, and fabs.

  • Apple Strategy Teardown
    Apple Strategy Teardown The maverick of personal computing is looking for its next big thing in spaces like healthcare, AR, and autonomous cars, all while keeping its lead in consumer hardware. With an uphill battle in AI, slowing growth in smartphones, and its fingers in so many pies, can Apple reinvent itself for a third time? In many ways, Apple remains a company made in the image of Steve Jobs: iconoclastic and fiercely product focused. But today, Apple is at a crossroads. Under CEO Tim Cook, Apple’s ability to seize on emerging technology raises many new questions. Primarily, what’s next for Apple? Looking for the next wave, Apple is clearly expanding into augmented reality and wearables with the Apple Watch AirPods wireless headphones. Though delayed, Apple’s HomePod speaker system is poised to expand Siri’s footprint into the home and serve as a competitor to Amazon’s blockbuster Echo device and accompanying virtual assistant Alexa. But the next “big one” — a success and growth driver on the scale of the iPhone — has not yet been determined. Will it be augmented reality, healthcare, wearables? Or something else entirely? Apple is famously secretive, and a cloud of hearsay and gossip surrounds the company’s every move. Apple is believed to be working on augmented reality headsets, connected car software, transformative healthcare devices and apps, as well as smart home tech, and new machine learning applications. We dug through Apple’s trove of patents, acquisitions, earnings calls, recent product releases, and organizational structure for concrete hints at how the company will approach its next self-reinvention.

The iPhone has come a long way in ten years—so long, in fact, that the design has cycled back a bit, and this iPhone looks more like the original than we've seen in a long time. Except of course for that camera bump, and shiny stainless steel rim, and glass back, and Lightning connector... As was the case with the iPhone 8 earlier this year, Apple has banished the unsightly (and environmentally responsible) regulatory markings from the back of the iPhone X. Jony finally has the featureless smooth backplane you know he's always wanted. Hopefully these phones still make it to recyclers without the hint and don't get dumped in the trash. Before we dive in blindly, let's get some 10-ray X-ray recon from our friends at Creative Electron. Here's what we found: Not one, but two battery cells. That's a first in an iPhone!

THREE-DIMENSIONAL SCENE RECONSTRUCTION USING MULTIPLE MICROSOFT KINECTS THREE-DIMENSIONAL SCENE RECONSTRUCTION USING MULTIPLE MICROSOFT KINECTS A thesis submitted in partial fulfillment of the requirements for the degree of Master of Science in Computer Science By Matthew Thomas Miller University of Arkansas Bachelor of Science in Computer Science, 2009 May 2012 University of Arkansas ABSTRACT The Microsoft Kinect represents a leap forward in the form of cheap, consumer friendly, depth sensing cameras. Through the use of the depth information as well as the accompanying RGB camera image, it becomes possible to represent the scene, what the camera sees, as a three- dimensional geometric model. In this thesis, we explore how to obtain useful data from the Kinect, and how to use it for the creation of a three-dimensional geometric model of the scene. We develop and test multiple ways of improving the depth information received from the Kinect, in order to create smoother three-dimensional models.

  • Re-Identification with RGB-D Sensors
    Re-identification with RGB-D sensors Igor Barros Barbosa1;3, Marco Cristani1;2, Alessio Del Bue1, Loris Bazzani1, and Vittorio Murino1 1Pattern Analysis and Computer Vision (PAVIS) - Istituto Italiano di Tecnologia (IIT), Via Morego 30, 16163 Genova, Italy 2Dipartimento di Informatica, University of Verona, Strada Le Grazie 15, 37134 Verona, Italy 3Universit´ede Bourgogne, 720 Avenue de lEurope, 71200 Le Creusot, France Abstract. People re-identification is a fundamental operation for any multi-camera surveillance scenario. Until now, it has been performed by exploiting primarily appearance cues, hypothesizing that the individuals cannot change their clothes. In this paper, we relax this constraint by presenting a set of 3D soft-biometric cues, being insensitive to appearance variations, that are gathered using RGB-D technology. The joint use of these characteristics provides encouraging performances on a benchmark of 79 people, that have been captured in different days and with different clothing. This promotes a novel research direction for the re-identification community, supported also by the fact that a new brand of affordable RGB-D cameras have recently invaded the worldwide market. Keywords: Re-identification, RGB-D sensors, Kinect 1 Introduction The task of person re-identification (re-id) consists in recognizing an individual in different locations over a set of non-overlapping camera views. It represents a fundamental task for heterogeneous video surveillance applications, especially for modeling long-term activities inside large and structured environments, such as airports, museums, shopping malls, etc. In most of the cases, re-id approaches rely on appearance-based only techniques, in which it is assumed that individuals do not change their clothing within the observation period [1{3].
