THETA V 360 is Output Dual-Fisheye , not EquiRectangular

#1

I have watch this video.
And How does it do that Output Dual-Fisheye?


#2

It’s a video from file, not a live stream.

When you save the video to the camera, it’s in dual-fisheye


#3

How can I get this file?
I get the file which is equirectangular format.
The file is from Android “Theta S” APP.


#4

plug your THETA V into your laptop or desktop computer with a USB cable, then open the camera as storage device.


#5

So…I have a question

The Equirectangular image transfer to dual-fisheye image.
It must have fisheye coordinate parameter of r.
r is named radius.
And it is a constant? What is it value?


#6

Are you looking for the precise lens parameter information, or a rough number?


#7

this might be useful for you for the rough approximation. Ricoh does not release the specific lens parameter information…


#8

Yes, it is the fisheye lens parameter of focal length.
I want this value number which is Ricoh define.


#9

When I get .mp4 file which is dual-fisheye format.
Which app can turn this .mp4 file to equirectangular format?
I will try to decompiler this app and find this value.
It sound so crazy…

The lens parameter information is not publicly available. If you are involved in a large project, you may be able to contact Ricoh directly and negotiate access to the information under NDA.

Is this a potentially large project?

This person used JPEXS Flash Decompiler to access XMP data. I don’t think he accessed the data you’re looking for. The desktop app is made with Adobe Air.
