Image Stitching for UAV remote sensing application

In this section are described basic methods for dealing with the stitching panoramic images.
The image stitching is a form of image mosaicing, than has become increasingly common, especially in the making of panoramic images.
The stitching is used in applications such as interactive panoramic viewing of images, architectural renderings, and other applications associated with the 3D modeling environment using images acquired from the real world.
A panorama is a picture that is made by combining a series of photos into one large picture. By combining a series of photos, it can provide a complete view of an area or location that cannot fit in a single shot.
The Panoramic Image Stitching is the process undertaken to create a panoramic image by overlapping a series of smaller images.
The first step for generating a panoramic image is to locate and capture images by deciding in advance what kind of image overview will be achieved. Depending on this can be taken one of many methods of acquisition.
After the images have been acquired, it may take some processing to be applied to images before stitching, because the distortions caused by the lens of a camera must also be corrected before the images are processed further.
Principally the process of stitching images is divided into two phases, the comparison and the blending of images .
During the first phase, the portions of adjacent images are compared to find the shifts necessary to align them.
Once the overlapping images have been compared, they must be joined together to form a single panoramic image. The process of image comparison is performed to make visually undetectable the transition between adjacent images. finally panoramic image is generated after the images were stitched. For the generation of panoramic images, the images can be acquired using a relatively inexpensive camera and the image viewing angle is determined by the user. The stitching image is greater resolution panoramic image captured from a panoramic camera.
