A fisheye lens is an ultra wide-angle lens that produces strong visual distortion intended to create a wide panoramic or hemispherical image. [4][5]: 145 Fisheye lenses achieve extremely wide angles of view, well beyond any rectilinear lens. Instead of producing images with straight lines of perspective (rectilinear images), fisheye lenses use ...
In mathematics, a stereographic projection is a perspective projection of the sphere, through a specific point on the sphere (the pole or center of projection ), onto a plane (the projection plane) perpendicular to the diameter through the point. It is a smooth, bijective function from the entire sphere except the center of projection to the ...
Panomorph. A panomorph lens is a particular type of wide-angle lens specifically designed to improve optical performances in predefined zones of interest, or across the whole image, compared to traditional fisheye lenses. [1] [predatory publisher] Some examples of improved optical parameters include the number of pixels, the MTF or the relative ...
ptgui.com. PTGui is a panorama photo stitching program for Windows and macOS developed by New House Internet Services BV. PTGui was created as a GUI frontend to Helmut Dersch 's Panorama Tools. It features its own stitching and blending engine [2] along with compatibility to Panorama Tools.
Fisheye lenses, which take hemispherical views, utilize this type of distortion as a way to map an infinitely wide object plane into a finite image area. In a zoom lens, barrel distortion appears in the middle of the lens's focal length range and is worst at the wide-angle end of the range. [2]
Website. easypano .com. Panoweaver is an image stitching app. 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. [2]
DxO ViewPoint is image geometry and lens defect correction software developed by DxO. It is designed to automatically straighten distorted perspectives caused by the lens used and the position of the photographer. The software claims to be able to make precise corrections to lens flaws through its use of DxO's database of calibrations (called ...
