Making QuickTimeVR Panorama


Step1
I am using custom VR camera like above.
Camera is <CANON EOS Kiss>, Lens is <SIGMA 8mm>.

Step2
Take 7 shots.
Only 10 to 20 seconds to take it for a point.

Step3

No.1

No.2

No.3

No.4

No.5

No.6

No.7
The shots becomes like above.
Since I used circular fish-eye lens, the picture is much distorted. Picture format is JPEG large (3072*2048pixel).

Step4
Crop original pictures to 1800*1800 pixel square in the Photoshop.
It is for faster process at later part, and done by batch commands.

Step5
Load the cropped pictures into the CINEMA 4D.
When opening the template scene file, the view is already VR panorama.
If there are problems like <distortion>, <seam>, <brightness>, <color>, <gamma>, <saturation>,
I can correct them here with 32bit/channel accuracy.
However in almost case, the settings are same (or very near) among shots which are taken in a day.

The 7 pictures are mapped on distorted 6 squares, and the squares make a cube. See the picture.
The picture above is a view from center of the cube. Here the view is drawn by OpenGL, so very fast.
The way is very same as "CubicNavigator".

After correcting parameters, render the cube faces to 6 VR pictures.
At the rendering, the CINEMA 4D blends connected pictures near edges, and apply filters (like sharp)
CINEMA 4D can render 6 VR pictures in 2 or 3 minuts, also Network rendering is available.

If you want to know how do I do it, you can get demo version of CINEMA 4D from MAXON computer.
and scene file from here.

---

New scene file for the OdaibaVR is here. This may be the latest one for 8mm lens and 6 shots way.

Step6
The rendered pictures becoms like above.
Here I used a trick for "bottom view (right most)", to remove "side pole" automatically.
Originally the bottom view (No.6) is like this, and you can see poles at top and bottom in the picture.
Then I have took "one more bottom view (No.7)" with rotating horizontal axis (90 degree).
As a result, compositing the No.6 and No.7 with mask at side areas makes "pole-less" clear bottom view.

Step7
This is final VR panorama from the rendered pictures above. I used CubicConverter to make it.

Except Step1 to 3 (taking photograph), all conversion processes can be done automatically,
so I can make over 50 VRs in a day, as this quality.


Step8
This VR camera was my first try in last year. I will try to make better one in this year.
