Optics – Panoramic Lens Applications Revisited
Panoramic Lens Applications Revisited Simon Thibault* M.Sc., Ph.D., Eng Director, Optics Division/Principal Optical Designer ImmerVision 2020 University, Montreal, Quebec, H3A 2A5 Canada ABSTRACT During the last few years, innovative optical design strategies to generate and control image mapping have been successful in producing high-resolution digital imagers and projectors. This new generation of panoramic lenses includes catadioptric panoramic lenses, panoramic annular lenses, visible/IR fisheye lenses, anamorphic wide-angle attachments, and visible/IR panomorph lenses. Given that a wide-angle lens images a large field of view on a limited number of pixels, a systematic pixel-to-angle mapping will help the efficient use of each pixel in the field of view. In this paper, we present several modern applications of these modern types of hemispheric lenses. Recently, surveillance and security applications have been proposed and published in Security and Defence symposium. However, modern hemispheric lens can be used in many other fields. A panoramic imaging sensor contributes most to the perception of the world. Panoramic lenses are now ready to be deployed in many optical solutions. Covered applications include, but are not limited to medical imaging (endoscope, rigiscope, fiberscope…), remote sensing (pipe inspection, crime scene investigation, archeology…), multimedia (hemispheric projector, panoramic image…). Modern panoramic technologies allow simple and efficient digital image processing and the use of standard image analysis features (motion estimation, segmentation, object tracking, pattern recognition) in the complete 360o hemispheric area. Keywords: medical imaging, image analysis, immersion, omnidirectional, panoramic, panomorph, multimedia, total situation awareness, remote sensing, wide-angle 1. INTRODUCTION Photography was invented by Daguerre in 1837, and at that time the main photographic objective was that the lens should cover a wide-angle field of view with a relatively high aperture1. -

Ava Max Could Always Envision Her Dream, She Actually Went out and Made It a Reality on Her Own
For dreams to manifest into reality, it requires more than a fairytale wish… Truthfully, it takes hustle, heart, and a whole lot of attitude. For as much as Ava Max could always envision her dream, she actually went out and made it a reality on her own. Gathering billions of streams, multiplatinum plaques, award nominations, and acclaim from The New York Times, Rolling Stone, and many more, the international phenomenon projects an unbelievable personal journey into a poignant and punchy pop opus on her full-length debut album, Heaven & Hell [APG/Atlantic Records]. “Manifesting is really important to me,” she explains. “I put positive energy into my music. I know what I want to write, and there’s a story behind each song. It’s all about working hard and putting your heart and soul into it.” She started doing so as a kid. Prior to her birth in Milwaukee, Wisconsin, Ava’s parents emigrated from Albania to the United States. Without speaking a word of English, mom and dad held down three jobs each. However, both parents retained a passion for music. Among her earliest memories, Ava recalls her mother—a classically trained vocalist—singing opera aloud. The family relocated to Virginia where they eventually settled in their first house. Along the way, Ava clung to music, listening to Whitney Houston, Mariah Carey, and Shania Twain, to name a few. “At a very young age, I watched my parents really struggle in America,” she admits. “It was tough, and it impacted me in many ways. However, both of them always told me if they could make it here with no language and no money, then I could make it.” While in Virginia, she dove headfirst into music with the family staunchly behind her. -
Hardware and Software for Panoramic Photography
ROVANIEMI UNIVERSITY OF APPLIED SCIENCES SCHOOL OF TECHNOLOGY Degree Programme in Information Technology Thesis HARDWARE AND SOFTWARE FOR PANORAMIC PHOTOGRAPHY Julia Benzar 2012 Supervisor: Veikko Keränen Approved _______2012__________ The thesis can be borrowed. School of Technology Abstract of Thesis Degree Programme in Information Technology _____________________________________________________________ Author Julia Benzar Year 2012 Subject of thesis Hardware and Software for Panoramic Photography Number of pages 48 In this thesis, panoramic photography was chosen as the topic of study. The primary goal of the investigation was to understand the phenomenon of pa- noramic photography and the secondary goal was to establish guidelines for its workflow. The aim was to reveal what hardware and what software is re- quired for panoramic photographs. The methodology was to explore the existing material on the topics of hard- ware and software that is implemented for producing panoramic images. La- ter, the best available hardware and different software was chosen to take the images and to test the process of stitching the images together. The ex- periment material was the result of the practical work, such the overall pro- cess and experience, gained from the process, the practical usage of hard- ware and software, as well as the images taken for stitching panorama. The main research material was the final result of stitching panoramas. The main results of the practical project work were conclusion statements of what is the best hardware and software among the options tested. The re- sults of the work can also suggest a workflow for creating panoramic images using the described hardware and software. The choice of hardware and software was limited, so there is place for further experiments. -

Panorama Photography by Andrew Mcdonald
Panorama Photography by Andrew McDonald Crater Lake - Andrew McDonald (10520 x 3736 - 39.3MP) What is a Panorama? A panorama is any wide-angle view or representation of a physical space, whether in painting, drawing, photography, film/video, or a three-dimensional model. Downtown Kansas City, MO – Andrew McDonald (16614 x 4195 - 69.6MP) How do I make a panorama? Cropping of normal image (4256 x 2832 - 12.0MP) Union Pacific 3985-Andrew McDonald (4256 x 1583 - 6.7MP) • Some Cameras have had this built in • APS Cameras had a setting that would indicate to the printer that the image should be printed as a panorama and would mask the screen off. Some 35mm P&S cameras would show a mask to help with composition. • Advantages • No special equipment or technique required • Best (only?) option for scenes with lots of movement • Disadvantages • Reduction in resolution since you are cutting away portions of the image • Depending on resolution may only be adequate for web or smaller prints How do I make a panorama? Multiple Image Stitching + + = • Digital cameras do this automatically or assist Snake River Overlook – Andrew McDonald (7086 x 2833 - 20.0MP) • Some newer cameras do this by “sweeping the camera” across the scene while holding the shutter button. Images are stitched in-camera. • Other cameras show the left or right edge of prior image to help with composition of next image. Stitching may be done in-camera or multiple images are created. • Advantages • Resolution can be very high by using telephoto lenses to take smaller slices of the scene -

Paper prepared in cooperation with the Pacific Northwest Region. Abstract Hall, Frederick C. 2001 Ground-based photographic monitoring. Gen. Tech. Rep. PNW-GTR-503. Portland, OR: U.S. Department of Agriculture, Forest Service, Pacific Northwest Research Station. 340 p. Land management professionals (foresters, wildlife biologists, range managers, and land managers such as ranchers and forest land owners) often have need to evaluate their management activities. Photographic monitoring is a fast, simple, and effective way to determine if changes made to an area have been successful. Ground-based photo monitoring means using photographs taken at a specific site to monitor conditions or change. It may be divided into two systems: (1) comparison photos, whereby a photograph is used to compare a known condition with field conditions to estimate some parameter of the field condition; and (2) repeat photo- graphs, whereby several pictures are taken of the same tract of ground over time to detect change. Comparison systems deal with fuel loading, herbage utilization, and public reaction to scenery. Repeat photography is discussed in relation to land- scape, remote, and site-specific systems. Critical attributes of repeat photography are (1) maps to find the sampling location and of the photo monitoring layout; (2) documentation of the monitoring system to include purpose, camera and film, w e a t h e r, season, sampling technique, and equipment; and (3) precise replication of photographs. -
