  • 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.

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.

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.

The lens on a camera is a series of precision-shaped pieces of glass that, when placed together, can manipulate light and change the appearance of an image. Some cameras have removable lenses (interchangeable lenses) while other cameras have permanent lenses (fixed lenses). Fixed-lens cameras are limited in their versatility, but are generally much less expensive than a camera body with several potentially expensive lenses. (The cost for interchangeable lenses can range from $1-200 for standard lenses to $10,000 or more for high quality, professional lenses.) In addition, fixed-lens cameras are typically smaller and easier to pack around on sightseeing or recreational trips. Those who wish to become involved in fine art, fashion, portrait, landscape, or wildlife photography, would be wise to become familiar with the various types of lenses serious photographers use. The following discussion is mostly about interchangeable-lens cameras. However, understanding the concepts will help in understanding fixed-lens cameras as well. Figures 1 & 2. Figure 1 shows this camera at its minimum Lens Terms focal length of 4.7mm, while Figure 2 shows the110mm maximum focal length.

  • Precise Determination of Fisheye Lens Resolution
    PRECISE DETERMINATION OF FISHEYE LENS RESOLUTION M. Kedzierski Dept. of Remote Sensing and Geoinformation, Military University of Technology, Kaliskiego 2, Str. 00-908 Warsaw, Poland - [email protected] Theme Session C2 KEY WORDS: Close-Range, Resolution, Optical Systems, Accuracy, Camera, Non-Metric, Fisheye Lens ABSTRACT: Using fisheye lens in close range photogrammetry gives great possibilities in acquiring photogrammetric data of places, where access to the object is very difficult. But such lens have very specific optical and geometrical properties resulting from great value of radial distortion. In my approach before calibration, Siemens star test was used to determination of fisheye lens resolving power. I have proposed a resolution examination method that is founded on determination of Cassini ovals and computation of some coefficient. This coefficient modifies resolution calculations. Efficiency of my method was estimated by its comparison with classical way and statistical analysis. Proposed by me procedure of lens resolutions investigations can be used not only in case of fisheye lens, but also in case of another wide-angle lenses. What have to be mentioned is fact, that the smaller focal length of lens, the more accurate is the method. Paper presents brief description of method and results of investigations. 1.

  • Geometric Modelling and Calibration of Fisheye Lens Camera Systems
    GEOMETRIC MODELLING AND CALIBRATION OF FISHEYE LENS CAMERA SYSTEMS Ellen Schwalbe Institute of Photogrammetry and Remote Sensing Dresden University of Technology Helmholtzstr.10 D-01062 Dresden, Germany [email protected] Commission V, WG V/5 KEY WORDS: Fisheye lens, omni-directional vision, calibration ABSTRACT: The paper describes a geometric projection model for fisheye lenses and presents results of the calibration of fisheye lens camera systems based on it. For fisheye images the real projection model does not comply with the central perspective. In addition, the lenses are subject to considerable distortions. The fisheye lens projection follows an approximately linear relation between the inci- dence angle of an object point’s beam and the distance from the corresponding image point to the principle point. The developed projection model is extended by several distortion parameters. For the calibration of fisheye lens camera systems, a calibration room was created and equipped with number targets. They were arranged to have a good distribution all over the image. The reference object coordinates of the targets were determined with high precision. The calibration itself is done by spatial resection from a single image of the calibration room. The calibration parameters include interior orientation, exterior orientation and lens distortion. Be- sides the geometric model for fisheye lenses, the paper shows practical results from the calibration of a high quality fisheye lens on a 14 mega pixel camera as well as a consumer camera equipped with a fisheye lens. 1. INTRODUCTION For the purpose of deriving photosynthetic relevant radiation values from hemispherical images two tasks have to be solved.
