PTGui supports several of these cameras, including the Samsung Gear 360, Xiaomi Mijia Mi Sphere, Yi 360 VR and Ricoh Theta Z1. If an image from such a camera is loaded into PTGui, PTGui will actually add the same image to the project twice, with different cropping circles and masks, positioned at -90 and +90 degrees yaw. While this already results in a roughly stitched image, the images still need to be aligned for perfect stitching. This is due to small differences between individual cameras of the same type, resulting in different small offsets of the image circles. You only need to perform manual alignment once for each camera, the result can be stored in a template and re-used. It’s best to use a photo taken outside, with no objects close to the camera, to prevent parallax. PTGui will automatically load the same image twice. Go to the Control Points tab and add a few control points.Image 1 is the leftmost or topmost circular image Image 2 is the right hand or bottom one. Just click once on a point in image 1, then once on the same point in image 2. It can be helpful to use the Generate Control Points Here function: Shift+drag to create a rectangle, right-click in the rectangle and choose Generate Control Points here. Often this will find control points automatically. Optimize the project (menu Project -> Optimize).Īvoid placing control points on objects close to the camera since these will suffer from parallax.The result should be ‘good’ (otherwise you’ve probably misplaced a control point somewhere) Open the panorama editor (Control+E on Windows, Command+E on mac) and check the result.Do File | Save As Template and choose a suitable name.įor subsequent images the template can be used instead: Load a picture from the 360° camera, then do File | Apply Template and select the template created above.The template can also be used for batch conversion using the Batch Builder (PTGui Pro only): The images are aligned already and the panorama can be stitched by going straight to Create Panorama. Method: Multiple panoramas per folder with a fixed number of images. Source folder: (select the folder containing the unstitched images).Image file extension: leave empty, or enter ‘JPG’, ‘DNG’ (if applicable).Use template: (select the template you created above).Select ‘the batch stitcher will not run Align Images’.Finally, PTGui asks whether the projects should be sent to the Batch Stitcher.Press Yes and all your images will be converted. Keep in mind that all cameras with multiple lenses will produce images with parallax. Some stitching errors will be unavoidable, especially in small rooms or with objects close to the camera. Also see: Q4.PTGui is a program for creating panoramic images from several photos. With its help it is very easy to make panoramas of all kinds, from simple, glued from 2 frames of pictures, to interactive spherical gigapixel panoramas. The highest quality panoramas are achieved when shooting from a tripod with a special panoramic head. USING MASK TOOL IN PTGUI PRO SERIESīut, to get a good result, you can even take a series of photos for a panorama from the hands, just turning the camera around its axis and taking pictures. PTGui is able to automatically align images and achieve seamless gluing of the finished image. All you have to do is to make sure that the edge of each next photo slightly overlaps with the edge of the previous one when you take the picture.
