Multicamera configuration

Introduction

Mapping and navigating with 3 cameras is way faster than with only 1 camera, beaucause the field of view is greater. However, it requires to synchronize the data coming from the 3 cameras in order to perform SLAM, and to get decent results.

Enable hardware synchronization

Simply use the hw_sync.launch script to enable hardware sync on cameras plug in. If, for any reason, this script fails, follow the following tutorial by Intel for manually enable it: https://youtu.be/DSm7NYG5bZE

Tune cameras parameters

The easiest way is to set the desired parameters thanks to the realsense-viewer software. See the References section for more information about it.
