Stereopanoramas with Samsung Gear 360
Some experiments with this camera using the depthmap
method outlined here
. The basic workflow comprises
- Two images are required with the camera mounted a few centimeters (3-10) vertically apart.
In the two cases shown below the camera is mounted on a tripod, and
to adjust for the second shot. One image is used for the main source panorama while the
second is required to calculate the depthmap.
- Both images are remapped and stitched to equirectangular panoramas.
- A depthmap is generated by analyzing the dense optical flow
between these two panoramic images.
The flow in vertical direction correlates with the depth of the scene.
The 2016-model of the camera (Samsung SMC 200) was used. The source images for the first
panorama are stitched by Samsung's Gear 360 app,
those for the second one with a customized version of my software PTStitcher. The nadir regions of both panoramas
and the seam in the second one are edited. The images are displayed in a new version of
PTViewer3d, which has been updated to handle more platforms including several browsers on smartphones.
This looks like a fast and simple way to create stereo-panoramas. With a synchronized two-camera-setup,
this might well be suited for stereoscopic panoramavideos.
