This is because I introduced a bit of parallax on accident as I rotated the phone downwards to capture the bottom set of image points. So it should be clear that in order to avoid parallax, it is important to take all images from the same viewpoint. Note: Notice how just above the rock at the bottom right there is a ghosted portion of the same rock. Unlike other artefacts like barrel distortion, correcting for parallax errors is impossible the best one can do is attempting to mask the misalignments by retouching the stitched panorama afterwards. You may have to do a light meter reading for the brightest and darkest parts of your. focal length setting Distortion introduced by imperfect lenses Parallax (camera not. To eliminate the possibility of parallax errors (things not lining up properly) when stitching. Expose for your scene manually and dont change the exposure between shots. The panoramic images used in this article were made by James Rigg. Here's an example taken using the circular panorama mode: Calibrating a Panoramic Head for Your Lens By Dave Watts. Now, if you really feel a need for trained experts to help you in eliminating all your panorama image stitching problems, we can surely offer you great support. This technique has given me perfect or near perfect results each time I've used it. Panorama image stitching is a hard job, and do not let an ineffective program make it even harder when there are other impressive, robust and scalable software are available. It's a little tricky, and takes some getting used to, but this will minimize parallax and allow the image processing algorithms to stitch the shots together as accurately as possible. To take a horizontal panorama, pivot on the Y axis, to take a vertical panorama, pivot on the X axis. Often what I do is place the phone down on a rail or some thing that allows me to keep the phone level, then pivot at the point of the lens. To do so, hold the phone in a way that allows you to rotate or pivot about the camera lens. You want to avoid introducing parallax when taking a panorama shot. If you use your smartphone or camera to make a panorama with everything in the distance, there will be no stitching errors. During image processing this would cause improper stitching and sometimes doubling or ghosting because suddenly the same object is in two different places, or objects are no longer where they were relative to other objects. If you shift your head back and forth, you'll see that your hands shift positions relative to each other, with the hand closer to your face appearing to be to the left or the right of the further hand depending on which way your head moves. You can demonstrate this to yourself by holding your hands out level to your eyes one hand out, but closer to your face, and the other further away from your face. ![]() If you shift your phone to the left or right, then objects in the scene are no longer in the same positions relative to each other. Taking panorama shots requires you to move the phone, and in doing so, you might introduce parallax. When you hold your camera in place and take a single photo, each object in the scene is stationary, in a certain position relative to everything else.
