Seeing the impressive images of the Elphel-Eyesis 4pi camera I thought it’s time to tell you about the HomeSide 720°. Like the Eyesis its purpose is to capture panorama frames with a framerate of 5fps. The major difference is that the HomeSide 720° is mounted on a helmet. To have an acceptable weight it consists of only two instead of eight Elphel 353 delivering one forth of the resolution the 4pi does. Thus the camera is able to record 30MPix frames before stitching. Additionally it’s reconfigureable to enable HDR panorama frames.
More interesting probably is the purpose it was built for. We created the assembly for indoor virtual tours. After several drawbacks we finally have an approach which works very well. We do auto leveling, auto stabilization and path extraction by image analysis only. Furthermore we recognize crossing points where the user can decide where to go when the tour is shown in the player.
This is not so easy since we neither have GPS nor IMU data. Nevertheless its possible.
All this information goes into our new webplayer which reassembles the images to a virtual tour.
Have a look at the HomeSide 720° Virtual Tour
Click into the player and use the cursor keys to navigate. You may also click and drag to change the point of view. This tour was recorded with 10MPix i.e. one Elphel 353 with two sensors.
Important: The pi symbols shows a rendered tour, not recorded by the camera
At the moment we are improving the image quality. We are also looking for a partner to drive the development even faster to create stunning indoor virtual tours.
