I am a rookie in the direction of robot SLAM. I was recently researching panoramic cameras (ricoh theta s), and saw that your research on this camera on github is quite in-depth. So I would like to ask you, can this camera be triggered using ptp-ip control?
Best regards,

There is no support of Precision Time Protocol.
There is support for Media Transfer Protocol (MTP) over a USB cable.
Please provide more information on what you are trying to achieve.
There is no known way to achieve absolute synchronization of two THETA cameras.
Usually, in multicamera systems, you can have an external physical device, sometimes the camera itself to send an external physical signal to initiate a capture. This would ensure that the capture occurs at the same time instant. Even if I use a USB API, I believe absolute synchronization can only be guaranteed from a real-time operating system but not with normal Ubuntu distribution. Such synchronized data is a necessity for multi-view applications like for finding correspondence to estimate d…
If you are using the THETA S, this could be useful:
ROS package for Ricoh Theta S camera
This repository contains scripts for offline processing of raw data acquired from stereo spherical cameras (ex. Ricoh THETA) to obtain rgbd image sequences which can later be used for various SLAM functionalities.
For VSLAM, see this:
