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. -

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 -
Shooting Sharp Images: Gear and Techniques You Need
SHOOTING SHARP IMAGES: GEAR AND TECHNIQUES YOU NEED Steps you can take to ensure you’re shooting sharp images every time. “For with slight efforts how should we obtain great results? It is foolish even to desire it.” – EURIPIDES An image that looks perfectly sharp on the camera’s preview screen or your laptop display may print undesirably soft. This blog entry reviews ways to capture an image with as much sharpness as possible. You can always soften a print later, but putting sharpness in later is much trickier. Shoot It Right, Don’t Try to Make It Right It’s tempting to think you can fix sharpness problems later, in the computer. Don’t fall into this trap! Software sharpening has limits, and it’s always more efficient to do something correctly rather than have to try to fix it later on. What are the elements of shooting sharp images? BUY THE RIGHT TRIPOD Use sturdy support, adequate to your particular camera’s needs. Many people make uninformed decisions when buying tripods, and are often disappointed with the lack of improvement in sharpness. Here are some pointers on tripod shopping. A full blog entry on selecting the best tripod and head combination is on tap for a future post. Meanwhile, start here. Know the weight of the items the tripod needs to support. Tripods are rated for different amounts of supported weights, and a tripod designed to support 10 lbs (4.54 kg) will not do much good when supporting 40 lbs (18.14kg) of long lens, heavy camera, brackets, strobe and tripod head. -
Ground-Based Photographic Monitoring

Hall Author Frederick C. Hall is senior plant ecologist, U.S. Department of Agriculture, Forest Service, Pacific Northwest Region, Natural Resources, P.O. Box 3623, Portland, Oregon 97208-3623. 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. -

Identification of specific products does not imply recommendation of or endorsement by the Angelina and Neches River Authority, nor does it imply that the products so identified are necessarily the best available for the purpose. All information presented regarding equipment and software, including specifications and photographs, were acquired from publicly-available sources. Background • As part of our routine monitoring activities, standard practice has been to take photographs of the areas upstream and downstream of the monitoring station. • Beginning in the second quarter of FY 2011, we began creating panoramic images at our monitoring stations. • The panoramic images have a 360o field of view and can be viewed interactively in a web browser. • Initially these panoramas were captured using a smartphone. • Currently we’re using a digital SLR camera, fisheye lens, specialized rotating tripod mount, and a professional software suite to create and publish the panoramas. Basic Terminology • Field of View (FOV), Zenith, Nadir – When we talk about panoramas, we use the term Field of View to describe how much of the scene we can capture. – FOV is described as two numbers; a Horizontal FOV and a Vertical FOV. – To help visualize what the numbers represent, imagine standing directly in the center of a sphere, looking at the inside surface. • We recognize 180 degrees of surface from the highest point (the Zenith) to the lowest point (the Nadir). 180 degrees is the Maximum Vertical FOV. -

Bokeh has been defined as "the way the lens renders out-of-focus points of light".[6] However, differences in lens aberrations and aperture shape cause some lens designs to blur the image in a way that is pleasing to the eye, while others produce blurring that is unpleasant or distracting—"good" and "bad" bokeh, respectively.[2] Bokeh occurs for parts of the scene that lie outside the Coarse bokeh on a photo shot with an 85 mm lens and 70 mm entrance pupil diameter, which depth of field. Photographers sometimes deliberately use a shallow corresponds to f/1.2 focus technique to create images with prominent out-of-focus regions. Bokeh is often most visible around small background highlights, such as specular reflections and light sources, which is why it is often associated with such areas.[2] However, bokeh is not limited to highlights; blur occurs in all out-of-focus regions of the image. -
A Practical Guide to Panoramic Multispectral Imaging
A PRACTICAL GUIDE TO PANORAMIC MULTISPECTRAL IMAGING By Antonino Cosentino 66 PANORAMIC MULTISPECTRAL IMAGING Panoramic Multispectral Imaging is a fast and mobile methodology to perform high resolution imaging (up to about 25 pixel/mm) with budget equipment and it is targeted to institutions or private professionals that cannot invest in costly dedicated equipment and/or need a mobile and lightweight setup. This method is based on panoramic photography that uses a panoramic head to precisely rotate a camera and shoot a sequence of images around the entrance pupil of the lens, eliminating parallax error. The proposed system is made of consumer level panoramic photography tools and can accommodate any imaging device, such as a modified digital camera, an InGaAs camera for infrared reflectography and a thermal camera for examination of historical architecture.
