Panoramic Imaging: Sensor-Line Cameras and Laser by Fay Huang

By Fay Huang

Panoramic imaging is a innovative program and examine zone. This expertise has functions in electronic images, robotics, movie productions for panoramic monitors, structure, environmental reviews, distant sensing and GIS know-how. functions call for various degrees of accuracy for 3D documentation or visualizations.

This publication describes smooth applied sciences for shooting high-accuracy panoramic photographs and variety facts, particularly using sensor-line cameras and laser range-finders. It offers mathematically exact descriptions of the geometry of those sensing applied sciences and the mandatory details required to use them to 3D scene visualization or 3D illustration. The publication is split into 3 parts: 

  • Part One features a complete advent to panoramic cameras and laser range-finders, together with a dialogue of calibration to help coaching of kit prepared for use.
  • Part explains the concept that of stereo panoramic imaging, taking a look at epipolar geometry, spatial sampling, photo qc and digicam research and design.
  • Part 3 seems to be at floor modelling and rendering in keeping with panoramic enter facts, beginning with the fundamentals and taking the reader via to extra complicated concepts similar to the optimization of floor meshes and information fusion.
  • There can also be an accompanying web site containing high-resolution visible samples and animations, illustrating options mentioned within the text.

Panoramic Imaging is basically geared toward researchers and scholars in engineering or computing device technological know-how interested in utilizing imaging applied sciences for 3D visualization or 3D scene reconstruction. it's also of vital use as a sophisticated handbook to working towards engineers in panoramic imaging. briefly, the e-book is of price to all these drawn to present advancements in multimedia imaging technology

Sample text

All three rays project from 3D scene space, through the optical system, then towards the image, and are finally assumed to continue to infinity. The first ray L1 is assumed to be parallel to the optical axis; it passes through focal point F . The second ray L2 is assumed to be incident with focal point F; it refracts such that it leaves the optical system parallel to the optical axis. The ray L3 passes through the principal point H+ and continues from principal point H+ ; it leaves the optical system “parallel to itself’’, and can be assumed to follow the optical axis between H+ and H+ .

A 3D point (X, Y, Z) is mapped into a 2D point (x, y, z0 ), where z0 defines the position of the image plane. In the case of an optical system, formed by a single thin lens only, both principal planes can be assumed to be identical, forming the principal plane H , with a uniquely defined principal point H+ . 6. The focal length f or f is the distance between F and H+ , or between F and H+ , respectively. We now apply the above notions to identify three characteristic rays of Gaussian optics. All three rays project from 3D scene space, through the optical system, then towards the image, and are finally assumed to continue to infinity.

The book explains in a few chapters the operations involved in obtaining results like this. 1. What kind of data are available when using a laser range-finder which scans 3D scenes incrementally (rotating horizontally around its axis, and scanning at each of these positions also vertically within a constant range of angles)? 2. [Possible lab project] Implement a program which enables anaglyph images to be generated. , green and blue) channels of the right image for creating the anaglyph RGB image, also allow the R channel to be shifted relative to the GB channel during 3D viewing for optimum 3D perception.
