Video stitching is a technique used to produce large or high-resolution images. It takes multiple different overlapping images from separate points of view and ‘stitches’ them together to form one composite image. These images need to have an almost exact overlap with each other and be taken around the same time to maintain cohesiveness and avoid parallax, distortion, or light intensity issues. After taking all of these different images in, a program will then map each pixel from one image to another and align all of them into one coherent picture. This is an essential part of 180°, 360° and VR videos, as these require many different images from all angles and viewpoints to be stitched together to recreate every potential point of view in the entire area visible to the viewer.
