Photo stitching

Photo stitching is the process of perspective warping of images, such that they can be aligned perfectly. PTGui is a photo stitching application for Windows.

Assembling panoramas by simply overlaying them in a graphics program will usually not give good results, because of the perspective transformations that occur when a camera is rotated.

Further, every real life lens has a certain amount of distortion (barrel distortion or pincussion which will worsen the stitching results even further.

Panorama Tools solves this by warping the images and correcting for lens distortion. The images are positioned in 3D space, so that they match as best as possible.
