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. -

iPhone X Teardown Guide ID: 98975 - Draft: 2021-04-28 iPhone X Teardown Teardown of the iPhone X November 3, 2017 in Sydney. Written By: Sam Goldheart This document was generated on 2021-04-28 01:41:52 PM (MST). © iFixit — CC BY-NC-SA www.iFixit.com Page 1 of 26 iPhone X Teardown Guide ID: 98975 - Draft: 2021-04-28 INTRODUCTION Ten years ago, Apple introduced the very first iPhone, and changed the world. Today, we're taking apart Apple's 18th iteration—the iPhone X. With its rounded edges and edge-to-edge display, we're sure this is the iPhone Steve imagined all of those years ago—but now that his dream is realized, will it be as influential as the first? Time will tell, but for now we'll be doing our part to help you decide. Join us as we open Apple's crown jewel to see what makes it shine. A big thanks to Circuitwise for hosting our teardown down under, Creative Electron for X-ray imagery, and TechInsights for IC ID. It's serendipitous that we're in Sydney, because we've got an Australia store now. As we learn more, we'll be posting on Facebook, Instagram and Twitter. We've got a newsletter too if you're the email type.

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 X Is Here! Here's the Fillin' Inside That Glass Sandwich: A11
The iPhone X is here! Here's the fillin' inside that glass sandwich: A11 "Bionic" chip with neural engine and embedded M11 motion coprocessor 5.8 inch "all-screen" OLED multitouch Super Retina HD display with 2436 × 1125-pixel resolution (458 ppi) Dual 12 MP cameras (wide-angle and telephoto) with ƒ/1.8 and ƒ/2.4 apertures and OIS 7 MP TrueDepth camera with ƒ/2.2 aperture, 1080p HD video recording, and Face ID Support for fast-charge and Qi wireless charging Our A1865 global unit has broad cellular band support as well as 802.11a/b/g/n/ac Wi‑Fi w/MIMO + Bluetooth 5.0 + NFC. 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! A super-tiny logic board footprint. -

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. -

This thesis analyzes some of the impact that this new data may have on stock return models by comparing a model that uses the Index Price and Yesterday’s Stock Return to one that includes those two factors as well as average tweet Polarity and Subjectivity.
