Free Tools Photosynth
Free Tools Photosynth Making a Photosynth Creating the best synth starts with the right photos. Here are some key tips: • Take overlapping panoramas from different locations • Have lots of overlap between shots to get good matching • Limit the angles between photos (no more than 25 degrees – at least 15 per full rotation) • Pick scenes or objects with lots of detail and texture • Don’t crop your images before synthing • Rotate your photos to be ‘up’ correctly before synthing Once you have signed in, click the Upload button (top right of page) or click on the Create your Synth icon on the home page. (scroll down). If you do not have the software you will be prompted to download it first. Once it is installed you will see the Create a Synth button. You will see a pop-up window with Start a new synth button. Give your synth a name, tags (descriptive words) and description. Click Add Photos, browse to your files add them. Then click on the Synth button at the bottom of the page. Photosynth will do the rest for you. Making a Panorama Many photosynths consist of photos shot from a single location. Our friends in Microsoft Research have developed a free, world class panoramic image stitcher called Microsoft Image Composite Editor (ICE for short.) ICE takes a set of overlapping photographs of a scene shot from a single camera location, and creates a single high-resolution image. Photosynth now has support for uploading, exploring and viewing ICE panoramas alongside normal synths. Here’s how to create a panorama in ICE and upload it to Photosynth: 1. -

Tele Vue APO refractors earn a high yield of happy owners. 35 years of hand-building scopes with care and dedication is why we see comments like: “Thanks to all at Tele Vue for such wonderful products.” The care that goes into building every Tele Vue telescope is evident from the first time you focus an image. What goes unseen are the hours of work that led to that moment. Hand-fitted rack & pinion focusers must withstand 10lb. deflection testing along their travel, yet operate buttery-smooth, without gear lash or image TV-60 shift. Optics are fitted, spaced, and aligned using proprietary techniques to form breathtaking low-power views, spectacular high-power planetary performance, or stunning wide-field images. When you purchase a TV-76 Tele Vue telescope you’re not so much buying a telescope as acquiring a lifetime observing companion.

Immersion in Early Architectural Design in the Age of Computing By
Immersion in Early Architectural Design in the Age of Computing By Kartikeya Anil Date A dissertation submitted in partial satisfaction of the requirements for the degree of Doctor of Philosophy in Architecture in the Graduate Division of the University of California, Berkeley Committee in charge: Professor Yehuda E. Kalay, Chair Professor Andrew Shanken Professor Whitney Davis Summer 2018 Abstract Immersion in Early Architectural Design in the Age of Computing by Kartikeya Anil Date Doctor of Philosophy in Architecture University of California, Berkeley Professor Yehuda E. Kalay, Chair This dissertation proposes a concept of immersion as an integral aspect of a general theory of the (early phase) architectural design act in the age of computing. Computing has influenced design in two major ways – as a metaphor shaping contemporary understanding of the design process, and as a machine used in the practice. The history of the relationship between these two modes of influence is traced to locate immersion in a model of the architectural design process. Early design is explored in this study by a comparative study of design across variously technologically mediated sketching environments. This process is considered as an individual process. Collaborative design is set aside. Computing has influenced design in two ways – as a metaphor for the process and as a machine used in the process. These two types of influences could also be understood to define two distinct tracks along which research in computer aided design has been developed. As a machine, computing has been studied in the fields like evaluation simulations in various domains such as acoustics, energy consumption, structural analysis, emergency evacuations, generative models, and representational models. -
A Statistical Examination of Image Stitching Software Packages for Use with Unmanned Aerial Systems
A Statistical Examination of Image Stitching Software Packages For Use With Unmanned Aerial Systems John W. Gross and Benjamin W. Heumann Abstract There is growing demand for the collection of ultra-high spatial orthomosaic. This issue is typically addressed using aerial resolution imagery, such as is collected using unmanned aerial photogrammetric techniques. systems (UAS). Traditional methods of aerial photogrammetry One of the more conventional ways to handle the creation are often difficult or time consuming to utilize due to the lack of orthomosaics in aerial photogrammetry is through the of sufficiently accurate ancillary information. The goal of this use of automatic aerial triangulation (AAT) and bundle block study was to compare geometric accuracy, visual quality, and adjustment (BBA). In this method, software is able to utilize price of three commonly available mosaicking software pack- interior orientation (IO) information provided by the camera, a ages which offer a highly automated alternative to traditional global positioning system (GPS), and an inertial measurement methods: Photoscan Pro, Pix4D Pro Mapper, and Microsoft Im- unit (IMU) to match individual images together then adjust age Composite Editor (ICE).

Cosmography of OB Stars in the Solar Neighbourhood⋆

Alves2 1 Centro de Astrobiología, INTA-CSIC, Depto Astrofísica, ESAC Campus, PO Box 78, 28691 Villanueva de la Cañada, Madrid, Spain e-mail: [email protected] 2 Department of Astrophysics, University of Vienna, Türkenschanzstrasse 17, 1180 Vienna, Austria Received 25 July 2015 / Accepted 6 October 2015 ABSTRACT We construct a 3D map of the spatial density of OB stars within 500 pc from the Sun using the Hipparcos catalogue and find three large-scale stream-like structures that allow a new view on the solar neighbourhood. The spatial coherence of these blue streams and the monotonic age sequence over hundreds of parsecs suggest that they are made of young stars, similar to the young streams that are conspicuous in nearby spiral galaxies. The three streams are 1) the Scorpius to Canis Majoris stream, covering 350 pc and 65 Myr of star formation history; 2) the Vela stream, encompassing at least 150 pc and 25 Myr of star formation history; and 3) the Orion stream, including not only the well-known Orion OB1abcd associations, but also a large previously unreported foreground stellar group lying only 200 pc from the Sun. The map also reveals a remarkable and previously unknown nearby OB association, between the Orion stream and the Taurus molecular clouds, which might be responsible for the observed structure and star formation activity in this cloud complex. This new association also appears to be the birthplace of Betelgeuse, as indicated by the proximity and velocity of the red giant. -
