Possibility of live streaming dual-fisheye images via USB

Is it possible to have THETA Z1 live stream dual-fisheye images via USB?

Unfortunately, there is no way to do this. The THETA S (old model) is the only model that could stream over the USB cable in dual-fisheye

If not, one of my colleague has ever developed an algorithm that converts fisheye images to perspective images, he thinks it is not that difficult to implement an equirectangular-to-perspective conversion as long as he knows the paramters that THETA built-in stitcher uses to perform the fisheye-to-equirectangular stitching. Has anybody in the forum ever done a similar job like this? Or does anybody know those parameters required to perform the conversion?

The stitching parameters of the lens are not disclosed. Other people are implementing the equirectangular to perspective without the lens distortion parameters and it appears to be good-enough in some cases.

If it is limited production, you can manually calibrate each camera and save the correction parameters to a settings file of your application.

Robotics Intelligence Laboratory using THETA S. However, they are also using the THETA V for some prototypes. You may want to contact the OP and ask what the current status is.
