This is notes from installation multi-raspberry pi camera (3 or 5 raspberry pi, each with a camera). The camera images is then collected in one single camera server.
This configuration guide is for the raspberry pi cameras and for the single camera server.

Prerequisites
It is assumed that mobotware is compiled for (or on) raspberry, and installed to /usr/local/smr, e.g. from the mobotware directory like this:
cd mobotware make sudo make install
Make takes a long time (one hour or so).
The make install installs the needed files into /usr/local/smr.local and links to this from /usr/local/smr. But do not put anything into /etc/rc.local.
Files needed
In mobotware a configuration example is in mobotware/build/config/gogo and mobotware/build/config/gogo/picam.
ls mobotware/build/config/gogo picam rhdconfig.xml ucamserver.ini ls mobotware/build/config/gogo/picam aukeeper.ini connectrhd.rule keepcam.rule keeplaser.rule keepnav.rule rc.local startKeeper ucamserver.ini
In mobotware/build/config/gogo/picam is the configuration files for the raspberry pi camera, the mobotware/build/config/gogo/ucamserver.ini is the configuration file for the single image collecting camera server (mostly for image recording).
Raspberry pi camera
The raspberry pi cameras in this example is named rpi6, rpi7, ... rpi10 as their hostname (in /etc/hostname).
Keeper
The keeper is a server that starts the cameraserver when needed (and restarts it if it crashes or gets stuck in other ways).
The Keeper should be started at reboot using the /etc/rc.local, like this line almostat the end of rc.local:
# rc.local ... # start keeper su -c "/home/local/startKeeper" local # exit 0
This starts a script placed in /home/local named startKeeper as the user local. This is to run as much as possible without root privileges.
Copy the start script to /home/local (beeing the user local:
cd cp mobotware/build/config/gogo/picam/startKeeper . chmod +x startKeeper
Make a live directory where the configuration files for keeper and camera server resides, and copy the ini-files:
mkdir live cd live cp mobotware/build/config/gogo/picam/*.ini .
The keeper uses some rules to monitor and restart the cameraserver, these should be in /usr/local/smr/bin/aursconf
