Here's the same panorama with the stitching errors fixed through manual stitching:Įxample panorama fixed by manual stitching.įinally, if you've allowed plenty of overlap and your software is still giving you stitching problems, get rid of it! It's hard enough creating great panoramas without putting up with dud software. If you can master this trick, you'll soon be able to tackle even the most difficult panoramas with ease. Most panorama software has a feature that allows you to view and adjust the stitch points. Stitching problems caused by a lack of visible features, or by highly repetitive features, can usually be solved by manually adjusting the stitching points. But even an ordinary tripod may help, and if you have to shoot hand-held, make sure you follow the rules for hand-held shooting (stand with your feet apart, hold the camera firmly with two hands, keep the camera horizontal, etc). The best way to do this is using a tripod with a panoramic head attachment. If your stitching problems are caused by parallax error, you'll need to take more care when shooting to try and rotate your camera around its nodal point. This is because lenses distort the picture more around the very edges of the frame - especially wide angle lenses. This makes working out your overlaps easy.īy allowing plenty of overlap, you also reduce problems with distortion. Many cameras have a feature that allows you to overlay the viewfinder with a grid that divides the frame into three parts horizontally and vertically. If you're constantly having trouble with panorama stitching errors, the first thing you must do is to make sure you are allowing plenty of overlap between fames (an overlap of one third is good).

Sadly, some of them just aren't very good at this job. Automatic stitching of images is another area where there are big differences between different software packages. An example of this might be an empty football stadium, with row after row of seats forming repetitive patterns across large portions of the image.īad software. Sometimes, the panorama stitching software can become confused if your images contain a lot of almost identical features repeated throughout the image. If your subject has large areas without many obvious features (like a blank wall or clear blue sky), this can make it hard to stitch. To automatically stitch the frames together, the photo stitching software relies on being able to match up features in each pair of images. This is a problem where close objects seem to change position between frames because the camera has changed position, due to not being rotated around the 'no parallax point' of the lens (also variously referred to as the entry pupil or nodal point of the lens). Distortion can be caused by a poor quality lens, by using an extra wide angle lens, or by having very close objects in the overlap zone. If there's a lot of distortion in the original images, it can make the images much harder for the software to stitch together. If you don't allow enough overlap between frames when shooting, your software may not be able to stitch the frames together properly.ĭistortion. Here are the six most common causes of stitching errors. Panorama stitching errors caused by distortion and lack of overlap. After stitching your panorama you might see some places where objects have been distorted, misaligned or cut in half during the panorama stitching process, like in this example: Stitching errors are a common problem in panoramic photography, where the photo stitching software made a mistake in lining up the images when it stitched them together.
