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

It’s a video from file, not a live stream. When you save the video to the camera, it’s in dual-fisheye

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

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

[image] Jiasheng_Wang: It must have fisheye coordinate parameter of r. r is named radius. And it is a constant? What is it value? Are you looking for the precise lens parameter information, or a rough number?

this might be useful for you for the rough approximation. Ricoh does not release the specific lens parameter information… theta360developers/video-streaming-sample-app/blob/master/samples/common/thetaview.js /* global THREE */ 'use strict'; /** * Copyright (c) 2016 Ricoh Company, Ltd. All…

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

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…

THETA V 360 is Output Dual-Fisheye , not EquiRectangular

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?
