(See How are virtual tour photos taken?). And this type of shooting/stitching isn't particularly easy to master. The Gimp or Photoshop alone can't do this particular job. Typically, people who shoot these kinds of images do so with a fisheye lens on a dSLR, with a panorama head, and stitch with packages like PTGui or Hugin.

Shooting and stitching a high-quality 360ºx180º is both equipment and labor intensive, so within your limitations of a) only using an Android phone camera and b) not wanting to spend a large amount of time post-processing, the Google apps (Cardboard Camera, Street View) that do Photospheres are probably your only way to do this, and you won't be able to achieve high resolution/quality, because you can't control the stitch, and you won't have the best optics or control for the job, not to mention a way to control rotating around the camera's no-parallax point, if you're shooting in a smaller space. If you're not starting with equirectangulars. Open both equirectangulars in the Gimp, and make a square image with the left-eye equirectangular above the right-eye equirectangular (equirectangulars are always 2x1 aspect ratio). Set your output format and size, and click the Stitch! button to make your equirectangular. Make sure the Field of View is set to 360 x 180, and that the Equirectangular projection is selected. Make sure the Lens Type is Rectilinear, and if the EXIF didn't pull in focal length and crop factor, guesstimate your field of view.Ĭlick on the GL preview button it the toolbar. Select Interface → Advanced, because the default Simple interface won't let you stitch a single image.Ĭlick the Add Images. The steps in my 2014 OSX version of Hugin are: The simplest way would probably be to just load your image into Hugin, set your projection to be Equirectangular, and stitch/output the panorama. If you want to use only a single 60º-coverage image, you're going to have to fill out the rest of the 'space', somehow. But you have to have equirectangulars because most users of Cardboard are gonna want to turn their head to see what's to the sides and behind them. With a 60º圆0º image, you've only covered 1/18th of the 360ºx180º view, after all.Ĭardboard, being first and foremost a VR viewer, requires equirectangular input to represent the entire VR environment, so whether or not you are interested in creating 360ºx180º panoramas, that's what it's expecting: either a single equirectangular for mono view, or two stacked equirectangulars (left on top of right) for stereo view. You can't do it without leaving most of it black. How would you represent an image with a 60° span without just leaving Also, this question is not about 360 panoramas, so if the equirect-pano format is the way to go, how would you represent an image with a 60° span without just leaving most of it black? (FYI, even if compression culls out all those black pixels on disk, the same is not true when the app loads it into RAM, which could cause apps to crash attempting to load high resolution images.) Google's docs mention the 'equirect-pano' format, but I don't see any documentation on that at this time. What format is right for a stereoscopic image to be compatible? What metadata needs to be on an image for a viewer to recognize it as stereoscopic? What viewer app do you use? So probably, just creating a regular JPEG consisting of two images side-by-side isn't enough.

I should be able to open a viewer app and switch to Cardboard view, including scanning the QR code for the specific Cardboard viewer, and have the stereoscopic image render correctly for that viewer. Note that this question is specific to Google Cardboard. I use Gimp, and have a reasonably good 13MP camera on my phone. I need to be able to do it with one camera, and without having to spend more than a few minutes editing an image (not counting the learning curve). I welcome them all, and I'll upvote every answer I learn something from, but I personally need a solution that is fairly accessible.

This question is mostly how to edit two images into one that can be viewed with Cardboard, but if you have tips on equipment to use to take the stereoscopic images in the first place, those are very welcome as well.

If you have created stereoscopic (NOT panoramic) images for Google Cardboard that you're proud of, please outline your process. I just got some vr cups and tried out the Cardboard Camera app, but the quality is pretty poor, and it's really intended for panoramas.
