[Discourse.ros.org] [Computer Vision / Perception] Cameras with 360 views in ros

Dirk Thomas via ros-users


Hi,

I noticed that more and more consmer-grade cameras with 360 FOV are available (Samnsung Gear 360, Nikon KeyMission, kodak pixpro 360, etc.)

Wonder if anyone successfully managed to do live streaming from these cameras in Ubuntu and to use them in robotic application.

Cheers

Davide

[Discourse.ros.org] [Computer Vision / Perception] Cameras with 360º FoV in ROS

Hi,

Disclaimer : self-promotion ^^.

A few years back I was playing with a 360 imaging using two uEye camera UI-3240CP  IDS-Imaging each mounted with 185 FoV fish-eye lens.
You can find short videos [here](https://www.youtube.com/watch?v=_zMrtydacsQ&list=PLNvEYwtozIQxCucfCjD_gbiH3vgZgUd4s).
Since then plenty of nice camera got to the market as you mentioned, unfortunately I didn't get to play with any of them.

Cheers.

I'm not sure about those cameras, but Econ Systems makes a rig for the TX1 that supports 6 cameras to provide 360FOV.

I can only talk about the Kodak PIXPRO SP360 (and 4K). They work as normal USB cameras. But connecting them via USB doesn't give them enough current to keep on forever (they drain more than they charge). Maybe fixable with some kind of powered USB cable?

My little work can be found here: https://github.com/uts-magic-lab/kodak_pixpro_sp360_ros

I have a short experience with SP360 (firmware version 1.0.5). I think it is important to highlight the differences of SP360 and SP360 4K since AFAIK only the SP360 4K version appears as V4L2 device.

The USB interface in SP360 serves only for storage access purposes. The only way I have found to stream the live image is setting the cam in WiFi mode and sniffing the MJPEG stream. Some instructions on that can be found [here](https://richard.milewski.us/blog/?page_id=47). Since this stream is actually meant for live preview on a mobile app, the quality and resolution is far from the cam is actually capable of. Although the cam has an HDMI output, it is only enabled in playback mode and does not provide live feed.

The SP360 4K has a webcam functionality and enables live stream to HDMI (now the external capture cards are also an option).
