A high resolution source image may have over 3,000 multi-resolution tiles making up the scene.

The completed 2:1 equirectangular images are saved as 16bit TIFF files, these are then used to create the multi-resolution tiles that the web server sends to your device when viewing. Processing from start to finish takes around 45 minutes, a lot of work goes into ensuring the horizon is straight and there are no stitching errors. It takes a lot less time to shoot the images than it does to process them! The drone takes around a minute to take the 26 images from the sky, and it takes just a few seconds to shoot the eight images from the ground.

The two images are then colour matched and blended together in Adobe Photoshop to produce a full 360° by 180° image. The process is repeated with the eight sky images shot in raw from the ground, and resized to the same horizontal dimensions as the aerial image. At this point anything above 35° from the horizon is missing as the drone can't shoot straight up. The photos are then imported into an application that stitches them into a 360° x 180° 'equirectangular' image. The aerial images are all shot in raw format, and they are developed in Adobe Lightroom ensuring the same settings are used for all the images. Whilst the drone is shooting from the sky, we use a ultra-wide angle lens attached to a special mount to take eight pictures of the sky which will be stitched into a separate 360° x 180° image. It uses a programmed grid pattern to ensure the images have enough overlap to stitch together. In the air at 400' (120m) our drone shoots 26 images from 35° above the horizon to the ground. The minimum image size in the tour is 200MP (20,000 pixels x 10,000 pixels), however the more recent scenes are 392MP (28,000 pixels x 14,000 pixels). The images are created by stitching together a set of photos that are taken all around the central point in special software. The 360° scenes are actually equirectangular images with a ratio of exactly 2:1, providing a 360° horizontal field of view, and a 180° vertical field of view. Here you'll find some resources about the tour, how 360° images work, and the equipment and techniques we use to shoot the scenes.

Resources Stitched original from PTGui (after step 3):Īfter step 4 and step 5 with content-aware fill applied and some corrections at the seam of the image: Is there a better way to complete authentic-looking skies? The last step in particular, using the clone stamp in the 3D workspace, is not exactly fast, somewhat limiting how much detail and effort I can put in.

Enter the 3D workspace in photoshop and use the clone stamp tool to blend over the seams of the imagesĪs you can see from a recent example ( completed photo in Google Maps 360 photosphere) below whilst this works to a degree, I'm still left with a blotchy-looking sky which I'm not completely happy with.

I have been taking quite a few 360 photos with my Mavic 2 Pro recently, and by far the hardest part is completing an authentic sky.
