Other mapping functions (for example Panomorph Lenses) are also possible for enhancing the off-axis resolution of fisheye lenses. With appropriate software, the curvilinear images produced by a fisheye lens can be remapped to a conventional rectilinear projection.
It supports telephoto, normal, wide angle and fisheye lens images into full 360*180 spherical panoramic image. [1] Panoweaver also supports exporting 360 panoramic images into Flash VR, QuickTime VR, Java-based VR tours and swf, and publish on Facebook.
The display is optimized to keep advantage of the improved performance in the zone of interest created by the panomorph lenses as opposed to algorithms for fisheye lenses which employ a linear mapping function to de-warp the image without any considerations for their departure from a perfect linear mapping (distortion).
DxO ViewPoint allows users to correct the horizon, keystoning, volume distortion (volume anamorphosis), and a number of lens distortions automatically or through sliders. Lens distortions include barrel, pincushion, and fisheye. DxO ViewPoint's corrections are based on DxO's data created through a large volume of images produced using different ...
The development of the source code of Panorama Tools was continued by some members of the original Panorama Tools mailing list. In December 2003 they initiated a free software project which is currently hosted by SourceForge. SourceForge requires that all hosted software is released under an open source license. For this reason Dersch's ...
Hemispherical photograph used to study microclimate of winter roosting habitat at the Monarch Butterfly Biosphere Reserve, Mexico.. Hemispherical photography, also known as canopy photography, is a technique to estimate solar radiation and characterize plant canopy geometry using photographs taken looking upward through an extreme wide-angle lens or a fisheye lens (Rich 1990).
This distortion can be reduced by using a swing-lens camera with a standard focal length lens. The FT-2 has a 50 mm while most other 35 mm swing lens cameras use a wide-angle lens, often 28 mm. [citation needed] Similar distortion is seen in panoramas shot with digital cameras using in-camera stitching.
Fisheye Visualization presented an interactive view of an album of photographs as an array of images where the sizes and positions were distorted as if a fisheye lens were following the cursor. This gave the user an overview of the entire album as small thumbnails while giving them a movable magnified view of some photographs.
